Post Description

Hey HN!

I'm Aditya, and today I'm excited to share Razix.

Razix lets you configure custom domains for multi-tenant platforms. It also provides an API so you can integrate it and let your B2B users add their custom domains.

It's special to me because this is my first SaaS whose core feature is written in Rust.

While building Razix, I:

- Created my first reverse proxy server - Learned to issue Let's Encrypt certificates using instant-acme - Learned how TLS and SSL work - And much more

All with minimal use of AI.
