Fider

What is Fider?

Fider is an open source product feedback tool that gives your customers a single public board to submit ideas, upvote requests, and discuss them in comments. Built with Go and React and released under the AGPL-3.0 license, it has been collecting feature requests for teams since 2017. Run it as managed Fider Cloud or self-host it with Docker.

What is Fider best for?

Product managers, SaaS teams, and startups that want a simple, brandable voting board to gather and prioritize feature requests in public — without paying for Canny or UserVoice per tracked user, or handing customer feedback to a third-party cloud. It fits best when you need a clean idea board, not a full roadmap-and-changelog suite.

What can Fider do?

• Public feedback board where users post ideas, upvote, and discuss in comments
• Organize posts with tags, custom statuses, and admin filters
• Passwordless sign-in via email magic links, plus OAuth (Google, GitHub, Azure AD, and custom OpenID Connect providers)
• Customize branding, the welcome message, and privacy (public or private board)
• Multi-language UI through community translations
• Push new posts and votes to Slack, Discord, or Microsoft Teams via webhooks
• Self-host with Docker and PostgreSQL, or use the managed Fider Cloud

Where does Fider fall short?

• No built-in roadmap view or changelog. Canny and UserVoice bundle both; Fider is a voting board only, so you announce shipped work elsewhere.
• No native two-way integrations with issue trackers. It can push to Slack, Discord, and Teams webhooks, but there is no direct Jira, Linear, or GitHub sync and no AI triage.
• SMTP is mandatory, not optional. Sign-in uses email magic links, so without a working mail provider (Mailgun, Amazon SES, Postmark, and similar) nobody — including you — can log in.

Is Fider free?

Yes — Fider is free and open source (AGPL-3.0) to self-host, and you only pay for your own server. Fider Cloud is the managed option: a free plan covers unlimited voters and members but caps at 250 feedback posts under fair use, and the Pro plan is $49/month and adds features like search-engine indexing.

What does Fider replace?

Fider is a self-hosted alternative to Canny and UserVoice — the paid feedback portals SaaS teams use to collect and rank feature requests. It covers the core submit-vote-discuss loop those tools charge for, while deliberately skipping their roadmap, changelog, and AI features.

FAQ

Is Fider open source? Yes. Fider is licensed under AGPL-3.0, and the full Go and React codebase is public on GitHub. You can self-host it for free.

Can I self-host Fider for free? Yes. Self-hosting is free — you only pay for the server. You will need Docker, a PostgreSQL database, and an SMTP mail provider for magic-link sign-in.

Is Fider a good Canny alternative? For a straightforward public voting board, yes — and it is free and open source. If you need roadmaps, changelogs, AI triage, or two-way Jira and Linear sync, Canny covers more ground.

What do I need to run Fider? A small server (about 1 GB RAM is plenty — the Go binary uses roughly 20–40 MB), Docker, PostgreSQL 16+, and an SMTP provider for passwordless email login.
