Quackback is an open-source feedback platform. It gives you voting boards where users submit and upvote feature requests, a public roadmap, and a changelog that notifies voters when their requested features ship.
It integrates with Slack, Linear, Jira, and GitHub, and exposes a full REST API. It also ships with an MCP server, so AI agents in Claude, Cursor, or Windsurf can search, triage, and respond to feedback on your behalf.
AGPL-3.0 licensed. Self-host with Docker or use the managed cloud. No user limits, no per-seat pricing.
