Adopt now+2.8k this week★ 150,055 · 21,900 forks

A polished self-hosted chat interface over your own models or API keys, with document upload and user accounts built in.

Mature enough to put in production this quarter.

Who it's for

Teams that want a private ChatGPT for staff — including the documents they should not paste into a public tool.

What it replaces

Per-seat subscriptions on a hosted chat product.

The catch

The licence now restricts removing its branding above a user threshold, so read it before white-labelling. You also own the hosting.

Your first hour

Run it against your existing API key, upload your internal handbook, and let one team use it for a week.

Licence check

Custom / check the LICENSE file. GitHub could not identify a standard licence for this repository, which usually means a custom or source-available one. Read the LICENSE file before you build on it.
