FeedbackFlow – Open-source feature voting integrated in iOS apps

Summary: FeedbackFlow is a self-hosted, open-source system that enables iOS app users to submit ideas, vote on features, and comment directly within the app. Built in pure Swift with zero dependencies and hosted on Supabase, it provides a privacy-focused, customizable solution for managing feature requests without third-party limitations.

What it does

FeedbackFlow collects user feature requests, allows voting and commenting, and presents an admin panel as a single HTML file. It uses device-based identity without requiring user accounts and communicates via URLSession without external SDKs.

Who it's for

It is designed for iOS developers seeking a free, self-hosted alternative to third-party feature voting tools with full control and privacy.

Why it matters

It solves the problem of limited or costly third-party feature request services by offering a lightweight, customizable, and privacy-first system that developers can host themselves.
