Open Rock – An open-source AI chat interface

Open Rock is an open-source chat app that runs as a website or Tauri desktop app and connects to every AWS Bedrock chat model in your region plus your own Gemma servers over HTTPS. It offers per-model settings, file uploads, a usage page with estimated costs, and keeps Bedrock API keys and Gemma tokens in the server process rather than the browser. Setup requires Node 20 or newer, with Docker and desktop build options documented.
