Unlimited boards and participants
Run as many retros as you want, with as many teammates as you want. There are no seat counts, no board caps, and no per-user pricing to track.
Retro Harbour
A free retro board. For agile teams, not board games.
Retro Harbour is a free online retrospective board for software and agile teams. Create a board, share the link, and run your sprint retro. The free tier has no sign-up and doesn't quietly expire after a two-week trial.
What you actually get
A real-time retrospective board built for software teams.
What "free forever" actually means
Everything is in the free tier. There is no paid tier behind the next click.
No sign-up, no login
Create a board, share the link, your team joins. There's no email verification step, no SSO to configure, and no admin permissions to hand out.
Real-time collaboration
Cards, votes, timers, and participants all sync live via WebSocket. Everyone sees the same board at the same time.
10 built-in templates
4Ls; Mad, Sad, Glad; Start, Stop, Continue; KALM; Went Well / To Improve; Sailboat; Starfish; Rose, Thorn, Bud; Lean Coffee; DAKI. All free, all customisable.
Markdown export
One click downloads the entire retro (participants, cards, votes, and actions) as a clean .md file ready for your wiki or issue tracker.
No "upgrade to unlock"
The trial doesn't expire. The premium tier doesn't exist. Nothing is locked behind a "this requires the Pro plan" prompt. You get the whole tool.
From blank board to action items
Start a free retro in under a minute.
01
Open the board
Click "Start a Free Retro," pick a template (or start blank), and name the retro. The board exists the moment you click create. No account required.
02
Share one link
Copy the board URL into Slack, Teams, or your sprint invite. Anyone with the link joins instantly. There are no invites to send or permissions to grant.
03
Write, group, vote
Your team writes cards privately, reveals them together, groups themes, and votes on what matters most. The board sorts by votes automatically.
04
Export and act
Capture action items in the dedicated Actions column. Export the whole board as Markdown for your wiki, ticket tracker, or sprint notes.
Quick disambiguation
Looking for a "retro board"? Here's what this one is.
This is a retrospective board
A digital whiteboard for the agile/scrum ceremony where a team reflects on the last sprint: what went well, what didn't, and what to change. Sometimes called a "retro," "sprint retrospective," or "agile retro."
It's not a board game
If you came here looking for retro-styled tabletop or arcade hardware, you're in the wrong harbour. This is software for software teams.
And it really is free
There is no paid tier and no "Pro" upgrade hiding behind a button. The whole product is what you get the moment you create a board.
FAQ
The honest questions about a free retro tool.
Is it actually free?
Yes. Unlimited boards, unlimited participants, and no credit card or trial period. There is no paid tier to upgrade to.
Do I need to sign up?
No. You create a board and share the link. That's it. There are no accounts to set up and no SSO to configure.
What is the catch?
There isn't one. Retro Harbour is open source (github.com/TamasNo1/retro). The hosted version is run by the maintainer for free because the running cost is small and a tool that needs procurement isn't a tool most teams will try.
How does this compare to paid retro tools?
For running a 60-minute sprint retro with a remote team, the core flow is the same: write privately, reveal, group, vote, capture actions, export. Paid tools add things like Jira/Confluence integrations and enterprise SSO. If you don't need those, this is the faster and cheaper option. See also our free retrospective tools overview.
Can I use it without registration?
Yes. That's the default. There's no registration option at all; the share link is the identity.
