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 moreAll with minimal use of AI.
