Open-source · self-hostable
Let your users bring their own domain — automatically.
Connect Domain detects the DNS provider, writes the records, verifies ownership, issues HTTPS, and serves the traffic. A day of support tickets becomes about thirty seconds.
The open-source alternative to Entri — from $0, not $249/mo.
How it works
Enter a domain
Your customer types theirbrand.com. We detect their DNS provider on the spot — with a logo.
Connect it
One click to authorize, or we write the records with a provider key, or hand over exact copy-paste records.
Go live
We verify ownership, watch propagation, issue HTTPS, and start serving — automatically.
Everything you need to offer custom domains
Nine building blocks. One clean flow.
Automatic DNS setup
Writes records across 19 providers — or a signed one-click Domain Connect.
Live provider detection
Show which DNS host a domain uses, with a logo, as the customer types.
Automatic HTTPS
Certificates issued and renewed at the edge (Let's Encrypt).
Reverse-proxy edge
Terminate TLS for the connected domain and route to your app.
Ownership verification
A domain goes live only once control is proven — value-checked.
Dashboard and API
A clean console for humans and a REST API for machines.
Webhooks
Know when a domain is added, verified, goes live, or drifts.
Multi-tenant
Every account isolated; per-tenant API keys sealed at rest.
Self-host or hosted
Run it on your own box, or use the hosted service.
19 providers auto-configured + Domain Connect
