Retro Harbour
The free online retrospective tool for agile teams. Real-time. No sign-up.
Retro Harbour is the simplest online retrospective tool for agile and scrum teams. Create a board, share the link, and run your sprint retro live with your team. No accounts, no paywall, no friction.
"At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly." - Agile Manifesto, Principle 12
100% free. No sign-up required.
No setup. No onboarding. Just a structured flow that guides your team from blank board to action items.
How it works
From blank board to action items in minutes.
02
Write Cards
Everyone writes their thoughts privately. Cards appear blurred to others until the facilitator reveals them.
03
Group & Discuss
Drag cards together to merge related topics. Have focused conversations around grouped themes.
04
Vote & Act
Vote on what matters most. Cards sort by priority automatically. A dedicated Actions column appears for capturing action items.
Built for speed and clarity.
The tools your team needs to run a real retro, nothing more.
Real-time sync
Cards, votes, timers, and phase changes sync live via WebSocket. Everyone sees the same board, instantly.
Export to Markdown
Download the full board, cards, votes, and actions, as a clean Markdown file. Paste it into your wiki, issue tracker, or doc tool.
No accounts, no tracking
Nothing to sign up for, nothing to install. Boards live behind an unguessable URL and disappear when you're done.
The ceremony
Every phase, beautifully handled.
Setup
Create a board in seconds
Choose a format, name the retro, and send one link. No accounts, invites, permissions, or onboarding flows are required before the team can join.
Phase 1
Write freely, think privately
Your team writes cards simultaneously. Each card is masked from other participants: they see that you're writing, but not what. This encourages honest, unbiased feedback without groupthink.
Phase 2
Reveal, group, and find patterns
All cards are revealed at once. Drag related cards onto each other to merge them into themes. The board updates in real-time for everyone, so you can collaborate on grouping as a team.
Phase 3
Vote on what matters
Each team member gets a set number of votes. Click cards to vote. Your votes are private until the round ends. Multi-vote and self-vote rules are configurable.
Phase 4
Capture actions, export results
Cards are sorted by vote count so the team focuses on what matters. Add action items collaboratively in real-time, then export the entire board as a clean Markdown file ready for your wiki or issue tracker.

Keep your retro on pace. The facilitator sets timers for writing and voting. Everyone sees the countdown live.

Why teams pick Retro Harbour
A free online retrospective tool with the speed of a sticky-note wall and the structure your sprint actually needs.
10-second start
Open the app, pick a retro template, share the link. Most online retrospective tools make your team create accounts before the first card. We don't.
No sign-up wall for participants
Guests join via link, no email verification, no install. Compare that to retro tools that gate every participant. See the no-signup retrospective tool overview.
Free forever, no seat limits
The free tier is the product, not a trial. Whole-team retros at zero cost, no per-user pricing, no "upgrade to add another teammate." Full breakdown on the free retrospective tools comparison.
Real-time, low-latency sync
WebSocket-based. Cards, votes, grouping, and the facilitator's phase changes appear instantly for every participant on the board.
10 retrospective templates
Start, Stop, Continue; Mad, Sad, Glad; 4Ls; Sailboat; Went Well / To Improve; Kanban retro; and more. Every template is fully editable.
Markdown export, no lock-in
Export the whole board to Markdown for your team wiki, sprint summary, or Slack post. Your retro outputs belong in your own tools, not locked inside ours.
