The Open-Source Alternative to Entri
Diego Alvarez

Entri turned custom-domain onboarding into a closed, per-domain SaaS starting at $249/month. Connect Domain does the same job and is open source and self-hostable — no per-domain fees, no vendor lock-in, and your customers’ DNS credentials never leave infrastructure you control.

Parity, honestly

We auto-configure 19 DNS providers today (Entri ~77), ship automatic HTTPS at the edge, a reverse-proxy plane, webhooks, and a REST API. See our live gap analysis for exactly where we match and where we’re closing in.
