This is an interesting project, congrats. I have a similar project and goals (free, light, fast portable os-like-dev environment) at http://shiro.computer, http://shiro.computer/about ( https://github.com/williamsharkey/shiro ).

You may find bits of Shiro's code useful as it has massive shimming work to get Claude Code, npm/node, git, various grep tools and isomorphic git and git diffs to work, and some weird features like virtual servers that create virtual ports to communicate to frames.

All the unix tools that Claude code are supported as well. It is also a typescript project and has similar architecture, and MIT license so there may be parts you can just straight import without much hassle.

Probably the hardest part to keep architecturally clean is the shimming required in js eval environment to make Claude Code and non-browser-native packages to run. But it is very nice once you have an agent able to work inside your browser os.

Great job and thanks for sharing Lifo. I am certain this will catch on once the implementations become more solid.

Hey, I was looking for something like this. Main purpose was to run openclaw. Is there a way to use browser as well?
