Chatbox is recommended by @0xSero (2026-06-14) as the top mobile client for self-hosted ML: users enter their host URL and API key, the app fetches all models from lmstudio/vllm, provides feature parity with the ChatGPT mobile app, and is distributed free and open-source.
@0xSero recommended Chatbox on 2026-06-14 as the #1 mobile app for anyone who self-hosts models.
If you self host anything the #1 mobile app I would recommend is Chatbox.
It just works, plugin on your url and api key, it’ll fetch all models on your lmstudio/vllm
It comes with all the same features in the ChatGPT mobile app, it’s free and open source.
Thank you Chatbox
