Is there a list of these "code sandboxes" floating around somewhere? It seems like it's going to be more and more important with LLMs playing more of a factor in development moving forward.

I know of https://modal.com/, which I believe is used by Codegen and Cognition.
Anecdotally-speaking, I hear that many companies in the LLM agent space roll their own sandbox solutions - I've heard of both Firecracker- and Kubernetes-based implementations.
I've got one that uses WebAssembly to run Python, Ruby, C/C++, JS: https://runno.dev/articles/sandbox/
You should repost that article on HN. WASI in the browser is awesome and I would love to see some discussion about it.
Is there a better way to sandbox Python other than using a webassembly build?
Yeah for sure: run it inside a virtual machine, or do some sort of docker magic.
You kind of need to pretend you are a whole computer for a programming language to be happy. There's built in assumptions they're running on a "real" computer. They assume they've got full access to network and disk. Installing packages often requires compiling C extensions, or running native binaries. All that stuff means the best way to sandbox is to virtualise a whole computer.
It's fun to do it with WebAssembly though, you get a lot of guarantees and it's quite light weight.

i work on E2B, we are open-source sandbox runtime used by Perplexity, Manus, Hugging Face among others.
