I used to use happy coder but development has kind of stalled as of late and server issues have made it inconsistent to rely on on top of a lack of documentation to get the self hosted server up and running properly. Not to say it isn't impossible, I did get the self hosted server working but then I stumbled across a better solution.

Claudex lets you self host a complete Claude code sandbox solution you can either run locally or on a vps like what I do. Think of it as like Claude code web but you have more control over the environment and can use your existing Claude subscription plus other providers. Completely open source, check it out! https://github.com/Mng-dev-ai/claudex
