Update 10/12/2026

Found a couple really cheap sandbox providers

If you need remote sandboxes for tasks or continuously running agents. They look interesting although I have not tried these yet:

Update 10/1/2026

The link to the sandbox field guide below was done by AI, and I keep running across more interesting sandbox projects that it did not find (seems like the default deep research in many of the mainstream AI agent/apps aren't very good!). I'm going to occasionally update this when I find some unique things that look interesting - i'll note if i tried them or not.

Wasm VMs, emulators, sandboxing

I haven't really dug into this stuff yet, but there are several projects related to running Linux VMs in a browser for isolation or just to run it in a browser.

This looks like a nice way to make a bunch of fast sandboxes for many AI agents, without having to use VMs, MicroVMs, WSL etc. There is an example on there you can try to run Pi agent in the browser.
