Connect a domain by DNS provider
Step by step guides to connect a custom domain from each supported DNS provider, with the exact records and how each provider's setup works.
CustomDomain supports 63 DNS and registrar providers. How a domain connects depends on what the provider offers: some support one click sign in, some take a scoped API token, and the rest use a guided flow where the app shows the exact records and verifies them for you.
How providers break down
Every provider is routed to the best setup it supports:
- 6 one-click (OAuth): you sign in to the provider and approve; no records to copy.
- 2 one-click (Domain Connect): you approve the change at the provider itself.
- 17 automatic (API token): you paste a scoped token once and the app writes the records.
- 38 guided manual: the app shows the exact records to add and verifies them automatically.
Whichever path applies, the app issues and renews TLS automatically and monitors for drift after the domain goes live.
Provider guides
These providers have a full walkthrough:
Nine of the 63 have a page. The other 54 do not need one to work: the connect flow shows you the exact records for your provider and verifies them either way, and Connect a custom domain covers the generic path end to end. A per-provider page exists where the provider's own dashboard is unusual enough that screenshots-in-prose save real time, so the queue is ordered by how often a provider actually turns up in support threads, not by market share. If yours is missing and its dashboard is the reason you are stuck, open an issue on CUSTOM-DOMAIN-APP/docs naming the provider, and say where the flow lost you.
The full catalog, including each provider's mode and dashboard URL, is served live at GET https://api.customdomain.ai/v1/providers/census. That endpoint is the source of truth for every count on this page.
