Atlassian finally put a date on it. Jira Data Center — the last self-hosted Jira you could actually buy — goes read-only on March 28, 2029, and the door to new data center subscriptions already shut for new customers on March 30, 2026.
That one announcement reshaped this whole category. For years, "Jira alternatives" meant "something less annoying than Jira." Now it also means "something we're allowed to keep running on our own servers."
So this guide splits the field in two. First, project management tools for cross functional teams who were never the target audience for issue tracking software in the first place. Then self-hosted Jira alternatives for engineering teams who need the code and the data to stay on their own infrastructure. Every price below was checked against the vendor's own pricing page in August 2026, and several have moved since last year.
Why teams are looking for Jira alternatives in 2026
Jira isn't bad software. It's the most configurable issue tracking product ever built, and for a 200-person engineering org running formal sprint planning, it still earns its keep. It's also still the category leader by a distance — Stack Overflow's 2025 Developer Survey had 46% of developers using it, second only to GitHub. But the same survey recorded something telling: GitHub displaced Jira as the collaboration tool developers most want to work with.
The problem is what it costs to get there — in money, in admin resources, and in the goodwill of everyone who didn't ask for it.
Jira Data Center and Jira Server are both going away
Atlassian killed Jira Server back in February 2024 (end of support is long past), pushing everyone toward either Atlassian Cloud or Data Center. Then in September 2025 they came for Data Center too. The Register called it exactly what it was: a cloud-only mandate.
The timeline that matters:
- March 30, 2026 — no new data center subscriptions or marketplace apps for new customers.
- March 30, 2028 — last day existing customers can buy new licences, apps, or expansions.
- March 28, 2029 — every Data Center instance goes read-only. Licences expire. Security patches stop.
Atlassian's own FAQ is blunt about the money, too: the per user cost of cloud is higher than Data Center. So if you're a bank, a defence contractor, a hospital group, or anyone running air gapped environments, you're not just being asked to migrate. You're being asked to migrate to a deployment model your compliance team may have already rejected, at a higher price.
The timing is awkward for another reason. Atlassian is pushing everyone into the cloud at precisely the moment the rest of enterprise IT is walking the other way: Barclays' CIO survey has repeatedly put the share of organizations planning to move at least some workloads back to private or on-premises infrastructure above 80%, and IDC's numbers point the same direction. Channelnomics has a useful sceptical read on how far those figures should be pushed — the honest version is selective repatriation rather than a mass exodus. Either way, "everything belongs in someone else's data centre" is no longer the default assumption it was in 2019.
So the surge of interest in self hosting isn't nostalgia. Self hosting is a hard requirement for a lot of organizations, and Atlassian no longer sells it.
Admin resources nobody budgets for
Ask anyone who has run a large Jira instance what their week looks like. Workflow configuration requests. Permission schemes. Custom fields that multiplied until search results got weird and page loads slowed significantly.
Jira gives you full control over process. The bill for that control is a person — sometimes a team — whose actual job is Jira. Smaller organizations rarely have those resources, so the configuration drifts, and eight months later nobody trusts the reporting. Add the Confluence documentation nobody updated and you get two systems telling different stories.
Cost management at scale
Jira Cloud is free up to 10 users. User number 11 moves you onto a paid plan, and the paid tiers start around $9.05 per user per month for Standard, roughly double that for Premium.
That's not expensive on paper. What gets expensive is everything bolted on: Confluence billed separately, Jira Service Management billed separately, and a stack of marketplace apps filling gaps in time tracking, reporting, and cost management. The self-managed side moved sharply too — Data Center list prices rose roughly 15% on 17 February 2026, taking the 500-user tier from about $51,000 to $59,000 a year. Plenty of teams end up paying two to three times the licence line once the plugin ecosystem is accounted for.
And this doesn't happen in isolation. Okta's Businesses at Work research put the average company at 101 deployed applications, rising to 131 at organizations above 5,000 staff. Jira's large ecosystem is a genuine strength right up until you're renewing eleven add-ons you can't name, inside a stack nobody has audited in two years.
It was never built for non technical teams
Cross functional teams generally want fewer concepts, not more. That's the whole reason the Monday alternatives and Notion alternatives categories exist at all — different teams need different amounts of structure, and one product rarely serves both ends well.
How to choose the right project management tool to replace Jira
Before the list, six questions worth settling. Most of these tools solve the same project management problem in different ways, so the differences that matter are structural rather than cosmetic. These six will cut your shortlist in half faster than any features table.Do you actually need self hosting?
Be honest here, because self hosting is the single most expensive requirement on this page.
Real reasons: regulated data that can't leave your infrastructure, air gapped networks, national data residency rules, source code you're contractually forbidden from putting in someone else's cloud.
Not real reasons: "we've always run our own servers." If that's the only argument left, SaaS will cost you less over three years than the sysadmin resources, hardware, backups, and upgrade weekends that self hosting quietly consumes.
What does your migration path look like?
This is where projects die. Jira exports issues to CSV and JSON reasonably well. Comments, attachments, workflow history, and automation rules usually don't survive the trip.
Check whether the target tool ships a native Jira importer, and read its migration documentation before you commit — Plane, YouTrack, and OpenProject all publish theirs. Accept upfront that you'll rebuild the two or three automations people actually notice, and archive the rest.
How much issue tracking depth do you need?
There's a real gap between "we need a task list with deadlines" and "we need custom workflows with conditional transitions, per-project custom fields, and a data model our QA process depends on."
Teams doing backlog management with story points and sprint planning need agile boards and estimates natively. Teams running client work need time tracker features and billable hours far more than they need a burndown chart. Testing teams need somewhere to record test runs, which several of these tools simply don't do.
Reporting, or the illusion of it?
A dashboard that looks busy isn't reporting. What you want is a report you can hand to a client or a finance lead without editing it first: hours by person, planned versus actual cost, project progress against deadline.
Some tools bury this behind paid tiers. Some require custom integrations with a BI product. Check before you commit, not after.
What do your enterprise requirements look like?
For enterprise buyers, three features decide the shortlist before anything else: single sign-on, audit logs and granular permissions. Almost every tool here parks those features behind an enterprise tier, and a couple of the open source tools don't ship them at all.
Scale is the other question, and it costs engineering resources to get wrong. Ask what support you get when it goes sideways, too — several tools here ship community forums and nothing else. Jira handles millions of issues without complaint. Some of these tools slow down well before that, so if you're moving 400,000 records, ask for a reference customer your size — and ask what happened to their reporting once workflows and dashboards were rebuilt.
Who maintains your open source stack in year two?
Open source is free the way a puppy is free. Redmine costs nothing to licence and plenty to keep patched. Most teams start shopping for Redmine alternatives not because the software failed, but because the one person who understood the Rails stack left the company.
Same logic applies to any self hosted version of anything — and to plenty of other tools that look free on the pricing page. Budget the maintenance resources, or don't self-host.
Best Jira alternatives for cross functional and non technical teams
These are cloud tools. No servers, no upgrade windows, no DBA. If your reason for leaving Jira is complexity rather than hosting, start here.
Worksection
The key features that matter here: Gantt charts with resource planning, Kanban boards, a built-in timer with hourly rates, and cost reports comparing planned against actual spend at project level. For an agency tracking hours across fifteen client projects, that combination is the entire project management stack. Auto-import from Basecamp, Asana and Trello ships on every plan, including free.
The honest caveat: Worksection is SaaS, not self-hosted. Premium adds on-premise backups, external file storage over S3 or FTP, IP restrictions, enforced 2FA, and a custom domain — solid security features, but they don't put the application on your own servers. If self hosting is a hard requirement, skip to the next section. If it isn't, it's the best fit here for teams of roughly 10–100 people, and it's why Worksection vs Jira keeps coming up for agencies, marketing departments, and product development groups. The Worksection overview walks through the interface if you want the tour before the trial.
On price, Business at $7.50 per user per month billed annually is roughly Jira Standard money, except Gantt, time tracking, and reporting are included rather than purchased separately.
Price: Free up to 5 seats · Basic $5/user/month · Business $10 · Premium $15 (25% off annually)
ClickUp
ClickUp is the everything tool. Docs, whiteboards, goals, twenty-odd view types, automation without code, and integrations with roughly a thousand other systems. Features per dollar, nothing beats it.
Two things the headline price hides. The free plan gives you unlimited members but only 60 MB of storage, and the $7 figure is the annual rate — month-to-month is $10. AI is also a separate line, with Brain at $9 a seat per month and Everything AI at $28, on top of your plan.
The trade-off is real, though. New team members regularly describe the first week as overwhelming, and admin-heavy setups can feel sluggish. If you're leaving Jira because it was too much software, be careful you're not buying more of the same problem in a friendlier colour scheme.
Good fit for product companies that want one workspace. Bad fit for small teams who need a shared to-do list and nothing else.
Price: Free · Unlimited $7/user/month billed annually ($10 monthly) · Business $12 ($19 monthly)
Asana
Clean, fast, and very good at cross-team workflows — campaign launches, onboarding programmes, quarterly planning. The timeline view handles dependencies without the ceremony of a full Gantt product.
Check the free plan before you get attached to it. Asana's Personal tier is capped at two users — not ten, as a lot of comparison posts still claim. Basic time tracking exists, but only from Advanced at $24.99, and timesheets, hourly rates and project budgets are a $5.99 per-seat add-on on top. For a five-person agency billing by the hour, that stacks up fast.
One more thing worth knowing if hosting matters to you: Asana states outright that it has no plans to offer an internally hosted version.
Price: Free for 2 users · Starter $10.99/user/month annually ($13.49 monthly) · Advanced $24.99 ($30.49 monthly)
Monday.com
Colour-coded boards, a no-code automation builder, and dashboards that non technical teams genuinely enjoy using. Monday sells itself on being pleasant, and it delivers.
The seat maths bites, though. Every paid plan starts at three seats and then climbs in blocks of five, so a two-person team still pays for three. Timeline and Gantt views don't appear until Standard, and time tracking waits until Pro at $24.
Where the core product struggles: proper agile workflows. No story points, no sprint burndown, no real backlog management on the work platform — monday sells a separate monday dev product for that. Dev teams will fight the standard boards. Marketing and operations teams love them. For a wider view of that middle ground, the Workzone alternatives breakdown covers similar territory.
Price: Free for 2 seats · Basic $12 · Standard $14 · Pro $24 per seat/month billed annually, minimum 3 seats
Trello
Still the fastest way to get kanban boards in front of people. Cards, lists, labels, deadlines, done. Power-Ups patch in what's missing.
The free plan is unusually generous on people — unlimited members — and stingy on structure: ten boards per workspace, and that ceiling is what pushes most teams to Standard. Timeline, calendar and dashboard views only arrive on Premium at $10.
Trello isn't planning software and doesn't pretend to be — dependency management and real reporting aren't there at any tier. Fine for small teams with one workflow; painful for anything portfolio-shaped. Worth reading the Trello alternatives rundown if you've already hit that ceiling, or the Kanban PM tools comparison if boards are all you need.
Price: Free (10 boards per workspace) · Standard $5/user/month annually ($6 monthly) · Premium $10 ($12.50 monthly) · Enterprise from $17.50 with a 50-seat minimum
Wrike
Wrike is the enterprise option in this group: request forms, approval workflows, proofing, cross-project resource management, and reporting that holds up under scrutiny. Agencies with formal client intake tend to land here.
Read the packaging before you read the price, though. Wrike rebuilt its plans on 21 January 2026, and the old Enterprise tier is now end-of-sale for new customers. Team caps at 15 users, so any agency past that size is really pricing Business at $25. Budgets and billable rates sit higher again, on Pinnacle. Seats are sold in blocks of five, ten or twenty-five, Business and above are annual-only, and Wrike Whiteboard is a $15 per-seat add-on.
It's also the most complex product in this half of the list. Compare carefully against the Wrike alternatives before signing. And if hosting is your reason for leaving Jira, note that Wrike's own FAQ says it's entirely cloud-based.
Price: Free · Team $10/user/month (2–15 users) · Business $25/user/month (5–200 users) · Pinnacle and Apex by quote
Zoho Projects
Cheap, capable, and hard to beat if your business already runs on Zoho CRM, Books and Desk. Gantt charts, blueprints that standardise repeatable workflows, issue tracking and time logs are all there.
Two caveats. The free tier's user cap is quoted as three on some of Zoho's regional pages and five on others, so check yours before you plan around it. And Zoho adds local VAT or GST on top of every listed price, which the plan cards don't show.
The interface feels dated next to other tools like Monday or Worksection, and the agile tooling is shallow. But at $4 per user, the value is difficult to argue with.
Price: Free for a very small team · Premium $4/user/month annually ($5 monthly) · Enterprise $9 ($10) · Ultimate $14 ($15)
TeamGantt
A specialist. If your project management problem is fundamentally a scheduling problem — construction, events, production — TeamGantt does timelines better than general tools do. Per-manager pricing with unlimited collaborators works out cheaply for teams with few planners and many doers. Similar logic to the GanttPro alternatives crowd.
Don't mistake the free plan for a team plan, though: it's one manager, two collaborators, one project and a 60-task ceiling. It's a demo, not a tier.
It is not an issue tracker. Don't ask it to be one.
Price: Free (1 manager, 2 collaborators, 1 project, 60 tasks) · Pro from $49/manager/month
Best self hosted Jira alternatives for engineering teams and devops teams
Now the other half. Every tool below runs on your own infrastructure — your own servers, your own cloud account, or air gapped environments with no outbound network access at all. This is where Data Center refugees should be looking.
One warning first: self hosting means you own uptime, backups, TLS certificates, database maintenance and upgrades. Every one of these tools has a free licence and a real operating cost.
Plane
If you want a modern interface and a short migration, Plane is probably the strongest option for replacing self hosted Jira today. The Community Edition is open source under AGPL-3.0, ships unlimited projects and work items, five layouts including board and Gantt, plus cycles, modules and intake — and it installs from a Docker Compose file or a Helm chart in well under an hour on 2 vCPUs and 4 GB of RAM. Modest server resources, in other words.
Two things make it unusually well suited to replacing Jira specifically. First, a native Jira importer, alongside importers for Linear, Asana and ClickUp. Second, a dedicated air-gapped edition with signed offline bundles for organizations that can't make outbound calls at all.
SSO/SAML, audit logs, approvals and governance workflows sit in the commercial edition. Watch which "free" you're reading about: Plane's open-source page says the self-hosted Community Edition has no user limits, while the hosted free tier stops at 12 seats. The free edition is genuinely usable either way, which isn't true of every open-core product — and because the source is public, you keep full control of the upgrade path.
Price: Community Edition free (AGPL-3.0) · Pro $6/seat/month · Business $13 · air-gapped edition quoted
OpenProject
The Community edition is free forever with no user limit — a meaningful advantage over Plane's free tier if you have 200 people to onboard. Installation runs through DEB/RPM packages or Docker, and the documentation is thorough, though it assumes Linux competence.
Behind the Enterprise licence: single sign-on, portfolio management, SharePoint and OneDrive integrations, and reporting extras. Check the plan comparison against your must-haves, because the gap between free and paid is wider than the marketing suggests.
Best for engineering-adjacent organizations doing waterfall and hybrid delivery — government, construction, R&D — rather than pure scrum shops.
Price: Free and self managed · Enterprise on-premises from around €7.25/user/month
Redmine
The original. Redmine has been running quietly on internal servers since 2006 and still ships releases. Out of the box: multi-project issue tracking, per-project roles, configurable statuses and workflow transitions, a Gantt chart, time tracking, wikis, forums, and a repository browser for Git, SVN and Mercurial.
What you don't get out of the box are kanban boards. That's a plugin, and the well-known agile plugin is a paid add-on. Workflows are configurable per role and tracker, as are the fields on every issue type, which is more than several paid tools manage, and the community resources around it are still active twenty years in. Which is Redmine's whole character — small core, large plugin ecosystem, and assembling it is your job. So is re-testing every plugin at each upgrade.
Pick Redmine if the licence line has to be zero and you already employ someone comfortable with Ruby on Rails. There's no vendor and no support contract — the project ships releases and the rest is yours. Otherwise the maintenance will find you.
Price: Free, GPL v2
Taiga
Taiga is opinionated agile software: scrum and kanban, backlogs, sprints, story points, burndown. For a startup that wants clean agile boards without Jira's configuration surface, it's lovely.
Self hosting it takes more work than Plane — separate frontend and backend services, PostgreSQL, RabbitMQ, coordinated upgrades. And the opinions are baked in. If your process doesn't look like textbook scrum, you'll be fighting the tool.
Support is community-run unless you buy a hosted plan, and it's worth checking the changelog before you build a process on Taiga: the hosted service moved to a different operator in 2024, and the release cadence isn't what it was during the project's busiest years.
Price: Free to self-host (MPL-2.0, no user limit) · hosted plans priced per instance, not per seat
YouTrack
The commercial vendor that never abandoned self hosting. JetBrains still ships a YouTrack Server edition that you install yourself, free for the first ten users on either deployment.
The key features cover Jira's ground closely: per-project custom fields, scriptable custom workflows, agile boards, built-in time tracking, a knowledge base, and a query language power users get fast at. The import wizard pulls from Jira, GitHub, GitLab, monday.com, and Zendesk, with continuous sync if you're migrating in stages.
Pricing above ten users works differently depending on where you run it. Cloud is per seat and slides down as the team grows; the Server licence is sold in fixed user packs with a one-year term rather than per seat, which is more predictable for a stable headcount and more annoying if you hire in ones and twos.
The interface divides people — some find it clunky, and large projects can load slowly. But for a team that wants Jira's depth, keeps the self hosting requirement, and doesn't want to maintain an open source stack, it's the obvious answer. The youtrack alternatives comparison shows how it stacks up against Linear and GitLab.
Price: Free up to 10 users on cloud and server · cloud from about $4.50/user/month annually ($5.40 monthly) · Server sold in fixed user packs
GitLab
If your developers already live in GitLab, you may not need a separate tracker at all. Issues, agile boards, milestones, epics on higher tiers, and CI/CD features in one product. Installing it on your own hardware has been a first-class deployment option since day one.
Be careful with the word free here. On GitLab.com the free tier caps at five users per top-level namespace; self-managed has no equivalent cap. And Premium at $29 a seat is the most expensive per-user price on this page by some distance — roughly four times Jira Standard. GitLab is a consolidation bet, and it only pays off if you're retiring other licences.
Where it falls short: anything non-engineering. GitLab issues are fine for developers and hopeless for the finance team. This is a consolidation play for pure software organizations, not a work management platform.
Price: Free tier includes issues and boards · Premium $29/user/month · Ultimate by quote
Azure DevOps
Azure DevOps is the most underrated Jira alternative for Microsoft shops. Azure Boards handles work item tracking, backlogs and sprints with Agile, Scrum and CMMI process templates. Repos, Pipelines, Artifacts and Test Plans cover the rest of the delivery chain, including testing. And unlike almost every other commercial vendor, Microsoft still sells a self hosted version: Azure DevOps Server, installed on your own infrastructure.
For an organization already on Entra ID, Visual Studio and Azure, the integration story is unmatched and the price is low. Stakeholder licences are free, so product owners and execs don't consume paid seats.
The catch: the interface feels its age next to Linear or Plane, and migrating away from Azure DevOps later is genuinely painful. Work item history and board configuration don't export cleanly anywhere. If Azure DevOps is where your team already tracks work, the linear alternatives piece is a useful counterweight on developer experience.

Planning the migration off Jira
A rough sequence that holds up:
- Audit first. Export every project, all your workflows, and every custom field. You'll find 60% of them haven't been touched in a year. Don't migrate dead weight into a new system.
- Budget the resources honestly. A mid-size migration eats one engineer for a month. Pretending otherwise is how these projects slip two quarters.
- Pick your cut-off. Move active work; archive everything else as CSV or JSON you can search later. Nobody has ever needed the full comment history of a 2021 bug inside a live tool.
- Run both in parallel for two weeks. Annoying, but cheaper than a rollback — and it doubles as testing on real data rather than a sample project.
- Rebuild automations by observation. Whatever people complain about missing in week one is your real automation list.
- Write the documentation as you go. Ten pages of "how we do things here" saves your support inbox in month two — and gives the next project lead something to inherit.
One practical note on data: whatever project management tool you pick, verify the export format before you migrate in. Portability is one of those features you only care about in five years, when the next vendor decides self hosting is no longer strategic.
So which is the right tool for your team?
Short answers, because the long ones are above.
You need self hosting and modern UX. Plane. Free to run, imports from Jira directly, least painful deployment on this list.
You need self hosting, unlimited free users and classical project planning. OpenProject.
You need self hosting and you're already a Microsoft organization. Azure DevOps Server.
You want Jira's depth without maintaining open source. YouTrack — free to ten users, on your server or theirs.
You're an agency or service business tracking hours against budgets. Worksection. Gantt charts, time tracking,cost reports and client access in one place, for less than you're paying Atlassian now — and support will help with the import.
Your problem is that Jira scared the marketing department. Monday.com or Asana. Both are pleasant, neither will run proper sprints.
You want everything in one workspace and you'll invest in setup. ClickUp.
And if none of that fits, the honest answer might be that Jira is still your best option — just on cloud, with a quarter of the custom fields and half the workflows you have today. Not every team needs to replace Jira. Plenty just need to stop over-configuring it, which is roughly the argument the Backlog alternatives piece makes about lightweight trackers generally.
Whatever you land on, run a two-week pilot on one real project before signing anything. Every project management tool on this page looks good in a demo. Comparison tables — including the one above — only tell you what tools can do. They can't tell you whether your team will actually open it on a Tuesday morning. If agile ceremonies are the sticking point, pilot a full sprint, not a week.
The bottom line
Three years is less runway than it sounds. Data Center goes read-only in March 2029, add-on sales stop a year before that, and enterprise procurement will eat a chunk of whatever's left. Pilot in 2026, migrate in 2027, and you'll never feel rushed.
Sort yourself into one of two piles. If self hosting is a genuine compliance requirement, your shortlist is Plane, OpenProject, YouTrack Server or Azure DevOps Server, and the real cost is maintenance rather than licences. If it isn't — and for most teams it honestly isn't — optimise for the thing that actually went wrong with Jira, which is usually that half the company found it unusable. That's where Worksection tends to land: Gantt charts, kanban boards, a timer with hourly rates, and cost reports comparing planned against actual spend, at roughly Jira Standard money.
Want to see whether it fits your projects? Book a demo and someone will walk through your setup with you, or start on the free plan and import from Basecamp, Asana or Trello in an afternoon.
Frequently asked questions
Is Jira going away?
No. The cloud edition is Atlassian's future and it isn't going anywhere. What's ending is the self-hosted line: Jira Server ended support in February 2024, and Jira Data Center reaches end of life on March 28, 2029, at which point instances become read-only.
What is the best free Jira alternative?
For engineering teams, Plane or OpenProject — both free, both self-hosted, no per-seat cost. For everyone else, YouTrack and Jira itself are free to 10 users, and Worksection is free up to 5 seats.
Can I still buy Jira Data Center?
Only as an existing customer. New customers lost access on March 30, 2026. Current subscribers can purchase new subscriptions and expansions until March 30, 2028, and renew through to the 2029 end-of-life date.
Which Jira alternative has the easiest migration?
Plane and YouTrack both ship native Jira importers, which makes them the shortest path. Expect issues, assignees, and basic fields to transfer cleanly, and automations, permissions, and attachments to need manual work regardless of the tool.
