Reflect together, without the overhead.
Create a board, share the link, add cards to Went well / To improve / Action items, reveal together — synced live between everyone on the board. No accounts, no subscriptions, nothing to install.
How a retro goes
Three requests, one shared board. Every participant sees the same state at the same time — reveal shows everyone's cards across all three columns at once.

Create or join
Pick a name, create a board with the creator key, and share the link — or drop in a board code someone sent you. Nothing to sign up for.

Add your cards
Everyone writes into Went well, To improve, and Action items. Cards show up live — what they say stays hidden until the board reveals. The header shows the live connection.

Reveal & discuss
One click flips every card at once, in every column. See what everyone wrote, and talk it through.
Own your cards
Anyone can reveal the board, but only a card's author can delete it. The one other exception: only the creator can close the board early.
Actually live
Cards, joins, and reveals push to every open tab instantly over a WebSocket — with Server-Sent Events as the fallback on networks that block them.
Hidden until revealed
Everyone writes in private; card text stays hidden from other participants until the board reveals.
Cleans up after itself
A board closes 2 hours after it was created, whatever is happening in it, with a warning near the end and a countdown at the finish. Need longer? Start a new one.
A port, not a copy
This is the Cloudflare port of proto-retro, rebuilt from the original Vercel app's code. Boards, the HTTP API, and the frontend carry over unchanged; underneath, each board is a single Durable Object that owns its state, serializes every write, and pushes changes to its own connections — no database, no pub/sub, no retry loops. Where the platform allowed better, the design changes on purpose: hibernatable WebSockets instead of SSE alone, so an idle board costs nothing, and boards that close themselves instead of waiting out a 4-hour TTL.
