Flux - Team chat with an extension marketplace and desktop app.
by•
Flux is a minimal team chat with channels, DMs, and an extension marketplace. Add AI, tasks, polls, GitHub or anything you want via extensions—no bloat. Native desktop app, OAuth, and a public SDK so teams can build their own extensions. For startups that want one fast workspace instead of a dozen tools.

We built Flux because we were frustrated with the current options.
Most chat tools feel like two extremes: either huge, heavy platforms full of features we never use, or very minimal tools where you can’t extend anything.
Flux tries to sit in the middle.
It starts simple — channels, DMs, fast UI — and then you add functionality through extensions. If you need tasks, polls, GitHub notifications, or an AI assistant, you install them. If you don’t, the workspace stays clean.
We’re launching with a first set of extensions (AI assistant, tasks, polls, GitHub, standup bot), and we’re opening a public SDK + marketplace so developers can build their own.
The desktop app is built with Tauri 2, so it stays lightweight and fast even as the workspace grows.
We’re a small team and this is our first public launch, so feedback means a lot.
Curious to hear — what extensions would you want to see in a team chat tool?
The way you’ve separated channels and extensions is smart - it keeps the core clean while allowing flexibility.
Are voice or video calls planned as part of the core experience?
@ntksh hi, first of all - thank for your feedback. Yes video and audio calls are in progress right now, and will be avaliable for use very soon!
