FeedbackFlow - Open-source feature voting for iOS apps. For free

Hey everyone! 👋 I'm an iOS developer, and for a while I was happily using a third-party service to collect feature requests and let users vote on what to build next. It worked great — until one day they quietly slashed their free tier limits. That was the moment I thought: why am I paying for something this simple? I just need a way for users to submit ideas, vote, and for me to see what matters most. So I built FeedbackFlow — a completely self-hosted, open-source feature request and voting system for iOS apps. Here's what makes it different: 🔹 Pure Swift, zero dependencies — no Supabase SDK, just URLSession 🔹 Self-hosted on Supabase (free tier is more than enough) 🔹 Admin panel is a single HTML file — no build step, no framework 🔹 Privacy-first — device-based identity, no user accounts needed 🔹 Optional email notifications via Resend 🔹 Fully customizable theming to match your app 🔹 Agent-friendly docs — you can feed the repo to an AI coding assistant and it'll set everything up It took me a weekend to build and it's been running in production in my apps since. I figured other indie devs might find it useful too. Would love to hear your thoughts and feedback! 🚀
