Fider

Fider is an open-source product feedback platform where customers submit ideas and feature requests, vote on priorities, and discuss them on a shared board. It centralizes feedback that would otherwise be scattered across emails and comments, giving teams a single place to see what users want and decide what to build next. Boards can be used for external customers or internally by a team.

Core capabilities include idea submission, voting, discussion threads, branding customization, multiple language support, and integration options. Boards are shared via a link that can be distributed by email, social media, or in-app notification. Fider has been open source since 2016 and can be self-hosted by those with the technical skill.

It is aimed at product managers, customer success teams, and startups, with particular mention of SaaS businesses, mobile app companies, and game developers. Packaging includes a free plan with a fair-use limit on feedback items, unlimited members and voting, and a paid Pro plan billed month-to-month that adds content moderation, unlimited feedback items, and SEO indexing. There is no long-term commitment, and cancellation is available at any time.
