What it does

OpenHive is a fully open-source team messaging platform — think Slack, but self-hosted and free. Built with Next.js, Supabase and LiveKit. Real-time channels, DMs, threaded replies, video/audio calls with screen sharing, file uploads, @mentions, slash commands, webhooks, bots, and a fully responsive UI. Clone, run npm run dev, and the setup wizard auto-provisions your database (23+ tables with RLS). No vendor lock-in. Try it: openhivedemo.com — MIT licensed, contributors welcome!

    The official Slack AI product looks great, but with limited access and add-on pricing, I decided to open-source the version I built. Especially for all the communities on Slack that would have to convert to paid and buy the upgrade to access the official SlackAI product/add-on which is not going to be financially viable in most cases. There's no plan to sell anything, just something I built as a way to learn some new tools that I thought others might get use out of.

It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
