FeltnerAI

Overview

FeltnerAI is a private, self-hosted chat server for OpenAI-compatible providers. It is made of three parts that share one codebase:

  • A standalone Rust server that stores your data and talks to your provider.
  • A shared React web application served directly by the server.
  • A cross-platform desktop Portal (built with Tauri v2) for connecting to one or more servers from your machine.

You host the server, point it at an OpenAI-compatible provider, create user accounts, and connect from the web app or a native client.
