AGPL-3.0 Licensed
Open source feedback tool
Collect feature requests, run voting, share a public roadmap, and publish changelogs. Self-host on your own infrastructure with no per-user limits. Free under AGPL-3.0.
Your users trust you with their ideas
You should own the infrastructure that stores them.
You own your data
Self-host on your infrastructure. Feedback never leaves your network. No third-party data processing agreements needed.
No vendor lock-in
Inspect the source, fork it, extend it. Export everything at any time. If you leave, your data leaves with you.
Free to self-host
Most feedback tools bill by tracked users and add seat fees, so the monthly cost climbs as you grow. Quackback is free to self-host, with unlimited users, boards, and feedback.
Built for teams that value transparency
Startups skip the SaaS bill. Regulated teams keep data on their own infrastructure. Developer-led teams extend the API and contribute upstream.

Frequently asked questions
Is Quackback really free?
Yes. Quackback is licensed under AGPL-3.0. You can self-host it on your own infrastructure with no per-user limits, no feature gates, and no monthly fees. The full platform — feedback boards, voting, roadmap, changelog, AI triage, and API — is included.
What is an open source feedback tool?
An open source feedback tool is a software platform whose source code is publicly available. You can inspect it, modify it, and host it yourself. This gives you full control over your data, eliminates vendor lock-in, and lets you extend the tool to fit your workflow.
How does Quackback compare to Canny?
Canny is a closed-source SaaS product. Its entry paid plan, Core, starts at $19/month (billed annually) and scales with tracked users. Quackback is open source with no usage limits. Both offer feedback boards, voting, and roadmaps, but Quackback adds a built-in MCP server for AI agents, self-hosted deployment, and no vendor lock-in.
Can I contribute to Quackback?
Yes. Quackback is developed in the open on GitHub. Contributions are welcome — from bug fixes and feature additions to documentation improvements. Check the contributing guide in the repository to get started.
What tech stack does Quackback use?
Quackback is built with TypeScript, React, and Node.js. The backend uses PostgreSQL for data storage. It deploys as a single Docker container or directly on platforms like Railway, Render, and Fly.io.
