Canny
Replaceable in one session with an AI coding agent.
A public feedback board: users post ideas, vote on each other's, and follow a roadmap showing what is planned, in progress and shipped.
Build me a public feedback board. STACK - Astro with a Node adapter, SQLite POSTS - Title, body, author, status: open, planned, in progress, shipped, declined - Status changes append to a history table; nothing is overwritten VOTING - One vote per account per post, no un-vote — a vote is an event - Store an optional account weight so paying customers can be counted separately, and show both numbers DUPLICATES - On submit, search existing posts by trigram similarity and show the closest three before allowing a new one - Merging moves votes and marks the loser as merged into the winner, keeping its URL alive THE ROADMAP - Three columns from status, ordered by weighted votes TELLING PEOPLE - When a post ships, email everyone who voted, once - Unsubscribe honoured per post and globally Include the schema, the similarity search and the merge routine.
What you lose
- Votes weighted by account value, so the loudest customer is not automatically the most important one
- Deduplication of near-identical requests, which is most of the work on a busy board
- Automatic notification of everyone who voted when a request ships
If you would rather not build
- GitHub Discussions, which is free and already there

our own opinion · changed only by a person
76/100
Verdict yes at 76. The board is easy; deduplication and the merge that keeps old URLs alive are what make it survive a year of use.
