WHAT IS IT?
Quackback is an open source platform for collecting and managing user feedback, designed as a self-hosted alternative to Canny, UserVoice and Productboard. Users vote and comment on requests through public boards, the team triages and prioritises from an admin inbox, and both the roadmap and changelog are published from the same interface.
WHY IS IT INTERESTING?
- Self-hosted, AGPL: You host, you control. No surprise quotas or per-seat pricing that explodes as the product grows.
- AI duplicate detection: New requests are automatically matched against existing ones and summarised, keeping boards clean as volume scales.
- Embeddable widget + mobile SDKs: Drop it into a web, iOS or Android app without redirecting users to an external page.
- 24 native integrations: Slack, Linear, Jira, GitHub, Intercom, Zendesk. Feedback lands where the team already works.
- REST API, webhooks and MCP server: Automation usable both from scripts and AI agents, which is still uncommon in this category.
- Modern TypeScript stack: TanStack Start, Drizzle ORM, Better Auth, Tailwind v4 / shadcn, Bun. Readable if you want to contribute or patch.
USE CASES
- Collect and prioritise feature requests for a SaaS without paying for Canny
- Centralise beta tester feedback on a public or private board
- Publish a product changelog tied to requests actually shipped
- Wire feedback into Linear or Jira to close the loop between support and roadmap
