Confluence's free plan is real — up to 10 users, unlimited pages and spaces, no time limit. What it doesn't include is a project board. If you're searching for a free Confluence alternative, the actual problem most teams have isn't the wiki — it's that the wiki and the board live in two different apps, and one of them costs extra once you grow past ten people. Comuna gives you a native wiki and notes next to a real Kanban, Table, Calendar and Gantt board, in the same free workspace, plus an AI coworker Confluence doesn't have.
Here's the honest breakdown — what Confluence's free plan actually includes, where Confluence still wins, and where a free Confluence alternative like Comuna fits better.
What does Confluence's free plan actually include?
More than people assume, to Atlassian's credit: up to 10 users, unlimited pages and spaces, 2GB of file storage, basic page templates, page versioning and history, roughly three whiteboards per user, and 10 automation rule runs a month. No trial countdown — it stays free as long as you're under 10 users.
What it doesn't include is the reason people search for a free Confluence alternative in the first place: advanced permissions, guest access, and any analytics are missing entirely, and Rovo — Atlassian's AI search and chat layer — isn't on the free plan at all. Cross the 10-user mark and Atlassian auto-upgrades you into a 7-day free trial of the Standard plan, which is a friendly way of saying you're about to start paying. And Confluence itself is a documentation tool — there's no Kanban board, no Gantt chart, no calendar. Most teams pair it with Jira for that, which is a second product with its own learning curve and its own bill.
Where does Confluence still win?
Genuinely, in a few places. Confluence's structure — Spaces, Pages, nested sub-pages, macros — is built for large, formal documentation: architecture decision records, onboarding wikis with dozens of departments, content that needs a real information hierarchy and page-level permission granularity. If your organization is already deep in the Atlassian ecosystem — Jira for tickets, Confluence for docs, cross-linking between the two — that integration is mature and not something a newer tool replicates overnight.
Confluence is also the more established name for IT and procurement review: the security paperwork, SSO options, and years-long deployment track record that a large enterprise buyer checks before signing off. Comuna is a younger product and hasn't built that history yet.
What do other "free Confluence alternatives" actually give you free?
Most of what ranks for this term falls into two buckets, and both leave a gap. The first is wiki-only tools — Slite, GitBook, Nuclino — built to replace Confluence's docs half well. Slite's free and paid tiers focus on fast page creation and an AI agent that flags when internal docs go stale; Nuclino leans into a lightweight editor with list, board, table and graph views for organizing pages. Both are genuinely good at documentation. Neither gives you a real project board — Nuclino's "board" view is a way to arrange wiki cards, not a Kanban with dates, checklists, and dependencies, and there's no Gantt or calendar in either.
The second bucket is project tools that bolt docs onto a board, like monday.com's workdocs, which can embed boards and widgets inside a document. That's a genuinely useful bridge — but monday's free plan caps out at two seats, three boards and 200 items total, with no Gantt, Timeline or Calendar view and no automations until you pay. You're trading Confluence's paywall for a different one.
Comuna doesn't split the difference — wiki and notes are native, next to a full board, not a plugin on either side. Kanban, Table, Calendar, Gantt, chat, notes and wiki are all included at the free tier, with no seat cap and no feature gate.
What does Comuna add that a feature checklist doesn't?
The AI coworker. Connect Claude or ChatGPT once — OAuth, no API key, about a minute — and your existing subscription becomes a member of the workspace, not a search box bolted onto the wiki. It can write and update notes and wiki pages, and it can also create and move cards, comment, and propose new work on the board — the same identity acting across both, every action signed with its own name in the activity feed.
That's a different thing from what the wiki-only tools offer. Slite's Agent flags when a doc is stale and drafts an update; Nuclino's AI helps you search. Useful, but neither one works a project card. Comuna's AI has a badge, a history of what it owns, and standing instructions you leave it — closer to what an AI coworker actually is than a smarter search bar. Worth being precise about the mechanism: it's pull, not push — the AI acts when you or a scheduled prompt trigger it, not something running unattended around the clock watching your docs.
Is Comuna a strictly better free Confluence alternative?
No, and it's worth saying plainly. If your organization needs deep page-level permission hierarchies, guest access for external reviewers, or a mature Jira integration for a large engineering org, Confluence (paired with Jira) does more than Comuna today, and paying for that is the right call once you're past 10 people. Comuna's macro and template library is also much smaller — if your docs rely on Confluence's structured macros (expand blocks, status badges, page trees), that's real rebuilding work, not a clean import.
The clearer fit: a small or mid-size team that wants docs and the project board in the same place instead of two tools, doesn't need enterprise-grade permission granularity yet, and is already paying for Claude or ChatGPT and wants that subscription doing real work — on cards, not just answering questions about a doc. See the full feature list for specifics, or read free forever for exactly what "no paywall" means here.
Migrating isn't instant. Confluence exports pages to XML or PDF; text content and images carry over cleanly into Comuna's notes and wiki, but page-tree permissions and macros need to be rebuilt by hand — that structure is exactly the depth Comuna doesn't try to match yet.
How do the free plans actually compare?
- Users — Confluence: up to 10 on free, then a forced trial. Comuna: unlimited, no cap.
- Wiki & docs — Confluence: unlimited pages/spaces, templates, versioning. Comuna: notes and wiki included, simpler structure, no macros yet.
- Project board — Confluence: none (pairs with Jira). Comuna: Kanban, Table, Calendar, Gantt and Diagrams, all on free.
- Chat — Confluence: none built in. Comuna: project-linked channels and DMs included.
- AI — Confluence: Rovo, not on the free plan. Comuna: connect your own Claude or ChatGPT subscription, no extra charge, as a real workspace member.
- Permissions — Confluence: page-level, granular, but paid-tier only. Comuna: workspace and board roles, simpler, included free.
Also worth reading: free Kanban with built-in chat, notes and an AI coworker if you're consolidating a whole tool stack, not just a wiki.
Is Confluence's free plan actually usable long-term?
Yes, for a team under 10 people — unlimited pages and spaces stay free indefinitely, with no trial countdown. The ceiling is the user count and the missing analytics, guest access and AI features, not the docs themselves disappearing.
Is there a free Confluence alternative with a project board built in?
Yes — Comuna includes Kanban, Table, Calendar and Gantt alongside notes and wiki, all at the free tier. Confluence has no native board; most teams pair it with Jira for that.
Does Comuna's AI actually write wiki pages, or just search them?
Both, and it also works the board. Connected via MCP, Claude or ChatGPT can draft and update notes and wiki pages and create, move and comment on cards, all under its own signed identity.
Can I keep using Confluence for docs and add Comuna just for the board?
You can, but most teams that switch do it because keeping two synced tools was the actual friction — not the docs or the board individually. If Confluence's permission depth matters for your org, it's fine to keep it and use Comuna's board with a link back to the relevant page.
Comuna is free forever — no credit card, bring your own AI. Spin up a workspace and try it.
