OpenHive: Open-source Slack alternative you can self-host in minutes

Hey everyone! 👋 I built OpenHive because I was frustrated with the lack of truly open-source, self-hostable team messaging platforms. Slack is great but expensive, and most alternatives are either too complex to set up or missing key features. OpenHive is built with Next.js, Supabase, and LiveKit. You can clone the repo, run `npm run dev`, and the setup wizard auto-provisions your entire database (23+ tables with RLS). No vendor lock-in, no per-seat pricing. ✨ Features: real-time channels, DMs, threaded replies, video/audio calls, @mentions, reactions, file uploads, and more. 🔗 Try the live demo: https://www.openhivedemo.com We're MIT licensed and actively looking for contributors — whether it's code, design, docs, or feedback. Every contribution helps! Would love to hear your thoughts and what features you'd like to see next. 🐝
