The System Design Behind My New SaaS
SMRTR summary
Katabench is a live coding platform for .NET developers where users write real C# code in the browser and run it against actual databases, getting back genuine performance data. It runs on three private Hetzner servers — an API server, a code execution worker, and a platform management server — connected through a self-hosted VPN. Untrusted code runs inside isolated, throwaway sandboxes with no network access, while auth and payments are handled externally through Clerk and Paddle.
