0cloud and BrowserCode

Both run coding agents in a browser tab. BrowserCode runs them on BrowserPod, a WebAssembly kernel; 0cloud runs a real arm64 Linux machine with apt, SSH and every native binary.

Other programs Emulated arm64, hot code compiled to WebAssembly Only builds made for their WebAssembly target

Where 0cloud is the better fit

When the agent needs more than Node.js: native binaries, apt packages, Python with pip, SSH to your servers.

  • apt install anything from Debian
  • git push over SSH
  • Every port, not an allowlist
  • Four agents, including opencode and Antigravity

Where BrowserCode is the better fit

When the agent only needs Node.js and speed matters more than compatibility.

  • JavaScript on the browser engine
  • A paid plan with hosted features

Is 0cloud free?

Yes. The machine runs on your computer, so there is nothing to rent.

Can I run native Linux programs?

Yes, any program built for arm64 Linux runs as it is.

Which is faster?

For Node.js both use the browser’s own JavaScript engine. For everything else, 0cloud emulates an arm64 processor with our own engine, so every Linux program runs, at emulator speed.
