# Razix – Custom Domain Management for Multi-Tenant SaaS

Razix – Custom Domain Management for Multi-Tenant SaaS is a product idea in the devtools category at difficulty 4/5, with strong market demand and an estimated revenue potential of $5k-20k/mo.

## Summary

SaaS platforms struggle to let customers use their own custom domains. Razix is an API-first service that handles custom domain configuration, DNS routing, and SSL certificate management for multi-tenant applications. B2B SaaS founders can focus on their product while Razix handles the infrastructure complexity.

## Why this is interesting

Multi-tenant SaaS adoption is accelerating and custom domain support has become a table-stakes feature — Vercel's wildcard domain infrastructure and the rise of white-label SaaS have made this pain point highly visible to developers who didn't previously encounter it. The closest competitor is Cloudflare for Teams' domain routing, though it's not purpose-built for this use case, and services like SSL-for-SaaS (Cloudflare's actual closest product) exist but require meaningful configuration work to wire into an application. The $5k–$20k/mo revenue band is plausible but tight — this is a low-frequency setup task rather than a high-volume transaction, so it lives or dies on seat count and tiered pricing tied to active custom domains, not usage spikes. The biggest risk is that Cloudflare's SSL-for-SaaS product, already widely trusted and priced aggressively, is good enough that developers won't pay for a wrapper around a problem they can solve in an afternoon with existing primitives.
