This project started off as a side-project on secure code execution because I wanted to figure out Repl.it and HackerRank worked. I tried experiments with different technologies like Firecracker [1], AWS Lambda [2] and gVisor [3]. They are all great technologies but I ended up with a solution using a combination of VMs and Docker containers to execute user generated code.

VMs + Containers is what Chromebooks use too to give a secure Linux environment. Checkout "crostini".

I guess great minds think alike! It's gratifying to see the smart engineers @ Google use a similar solution to solve the security problem. Unfortunately, it seems Crostini is tied heavily to ChromeOS.

Firecracker actually forked the technology pinning Crostini.

Looks like you have some great ideas here, I’ve been interested in code execution systems similar to this and would love to read your source code.

Actually I'm planning on releasing the system as a standalone API CodeRun [1].
