Collect feature requests, run voting, share a public roadmap, and publish changelogs. Self-host on your own infrastructure with no per-user limits. Free forever.
Your users trust you with their ideas. You should own the infrastructure that stores them.
Self-host on your infrastructure. Feedback never leaves your network. No third-party data processing agreements needed.
Inspect the source, fork it, extend it. Export everything at any time. If you leave, your data leaves with you.
Most feedback tools charge $79-$400/month and limit users. Quackback is free with unlimited users, boards, and feedback.
Open source feedback tools work for teams of every size. Here is who benefits most.
