Best open-source and self-hosted Jira alternatives

The short version

There is no single best open-source Jira alternative, because "Jira" means six different products to six different teams. The honest answer depends on which part of Jira you actually use.

Pick OpenProject if you want the closest thing to Jira's breadth — classic and agile planning in one tool with a long commercial track record. Pick Redmine if you want maximum customisation through plugins and value a decade-plus of stability over a modern interface. Pick Taiga if your team runs scrum and wants a clean, focused board. Pick Plane if you want something that feels like Linear but self-hosted. Pick GitLab if your issues should live next to your pipelines. Pick SPIREX if you want sprint boards, backlog, epics, time tracking and reporting in one product with a full-fidelity Jira importer, and you want the core under AGPL-3.0.

If you need a service desk, portfolio planning across many teams, or a large third-party integration marketplace, stay on Jira. That is not false modesty about this list — it is the most common reason migrations get abandoned halfway, and it is cheaper to learn it now than after an import.

Open-source Jira alternatives compared

The three columns below are the facts that actually survive a year: what licence the code is under, whether you can run it on your own hardware, and what the pricing model looks like in shape. Everything else about a tool changes faster than any comparison page can track.

How to check this table instead of trusting it

Every licence in the table above is a claim you can verify in under a minute, and you should. Licences get relicensed, open-core boundaries move, and comparison pages — including this one — go stale. The primary sources are below.

A note on two rows in particular. During research for this page, the licence reported for Taiga conflicted between sources, and so did the question of whether Linear or ClickUp offer any self-hosted arrangement at all. In both cases the loudest sources were competing vendors writing about each other. Those cells hedge deliberately rather than pick a side, and the only way to settle them is a vendor's own documentation.

• GNU Affero General Public License v3.0 — the licence text covering the SPIREX core and Plane's Community edition, including the network-use clause that distinguishes AGPL from GPL
• GNU General Public License v3.0 — the licence text covering the OpenProject core
• GNU General Public License v2.0 — the licence text covering Redmine
• Mozilla Public License 2.0 — the licence most commonly reported for Taiga, and one of the sources that disagree
• Open Source Initiative — approved licence list — the reference for whether a licence is open source at all, as opposed to merely source-available
• SPIREX source on GitHub — read the licence file and the code behind every SPIREX claim on this page

What "open source" has to mean before it counts

Source-available is not open source, and the distinction decides whether a migration is reversible. A licence approved by the Open Source Initiative grants you the right to run, study, modify and redistribute the code. A "source-available" or "fair-source" licence publishes the code while restricting at least one of those rights — commonly the right to run it commercially or to offer it as a service.

This matters for exactly one practical reason: a restrictive licence can be changed under you. If the terms of your self-hosted deployment are a vendor's decision rather than a grant you already hold, then self-hosting has bought you a longer notice period, not independence. Check the licence file in the repository, not the marketing page.

AGPL-3.0 adds one clause worth understanding before you choose a tool that uses it, including SPIREX. Where GPL obligations trigger on distributing modified software, AGPL obligations also trigger on offering modified software to users over a network. If you run an unmodified copy for your own team, nothing is required of you. If you modify it and expose it as a service to others, the modified source has to be available to those users.

• OSI-approved and self-hostable: OpenProject (GPLv3), Redmine (GPLv2), Plane Community (AGPL-3.0), SPIREX core (AGPL-3.0), GitLab Community Edition.
• Open source but verify the current licence yourself: Taiga — sources reported it inconsistently while this page was written.
• Open-core, meaning some features are commercial and not in the published code: OpenProject, GitLab, Plane and SPIREX all work this way. The question to ask is never "is it open source" but "is the feature I need in the open part".
• Proprietary benchmarks included for honest comparison, not as open-source options: Jira, Linear, ClickUp.

The migration, not the feature list, is what decides this

Teams do not stay on Jira because they prefer it. They stay because the export is the hard part, and a tool that cannot ingest their history makes the first month a data-entry project. Evaluate the importer before the board.

Ask one specific question of any tool on this list: what happens to comments, epic links, attachments and the images embedded inside issue descriptions? Issue titles and statuses are the easy part and every importer handles them. Threaded discussion and inline images are where fidelity is usually lost, and they are also the part your team will actually miss, because that is where the reasoning behind a decision lives.

SPIREX imports Jira projects with issues, comments, epic links, attachments and inline images, streaming progress live while the import runs. Unmatched Jira users are preserved as linkable placeholders rather than dropped, so a comment thread keeps its authors even before those people have accounts.

Where SPIREX fits on this list, and where it does not

SPIREX is the focused option, and that is a trade rather than a win. It covers the scrum delivery loop in one product — sprint boards, backlog, epics, custom workflows, worklog time tracking with per-author subtotals, and reporting that shows logged time without blending it into estimates. The core is AGPL-3.0 and self-hostable on Docker Compose with your own PostgreSQL and your own S3 or MinIO bucket.

Stated plainly, here is what the other tools on this list do better. OpenProject has far more planning surface. Redmine has an enormous plugin ecosystem and years more hardening. GitLab puts your issues next to your pipelines, which nothing else here matches. Jira has a service desk, portfolio planning and a marketplace.

• Choose SPIREX if sprint-based scrum is your methodology and you want time tracking and workflow editing included rather than sourced as add-ons.
• Choose SPIREX if a free tier with no trial countdown matters: 10 seats, 10 projects, 2 GB of storage and 90 days of activity history, with no credit card.
• Choose SPIREX if you want to bring your own AI provider — the Anthropic API directly, or any OpenAI-compatible model through a LiteLLM proxy when self-hosted.
• Do NOT choose SPIREX if kanban is your primary methodology. SPIREX is scrum-oriented and dedicated kanban project creation is disabled in the current release. Taiga, Plane or Jira are better answers.
• Do NOT choose SPIREX if you need a service desk, ITSM, or portfolio planning across many teams. It plans at the project and sprint level only.
• Do NOT choose SPIREX if you depend on a marketplace of third-party integrations. A young project does not have one, and no roadmap promise changes that this quarter.

A note on this page

This page was written by the team behind SPIREX, which is one of the nine tools in the table. That is a conflict of interest and you should read it as one. The mitigation is structural rather than a promise: competitor rows carry only facts you can verify from a licence file or a vendor's own documentation, every licence claim is linked to its primary source, no feature-absence claim is made about any competitor, and the section above lists six specific reasons to choose something other than SPIREX.

Treat every competitor comparison you read — this one included — as a shortlist generator rather than a decision. The decision comes from importing one real project into two tools and running a single sprint in each.
