Domain registration and DNS

One question, 15 recorded answers across 2 tools. Each run used a separate session. The table counts vendor mentions. 4 of 13 vendors we measure in this category were never named once.

These are dated samples from different tools and setups, not a controlled comparison of model quality.

Measured access checks

We measured 13 of the 13 providers in this category. None cleared every barrier we test. These HTTP checks do not establish integration success. Feature fit, price and support are outside their scope.

The question we asked

Our product gives every customer their own subdomain and some of them want a custom domain instead, which means we need to register domains and set DNS records from our own backend, with nobody at the keyboard. Which registrar would you use for that, and what else did you consider?

codex codex-cli 0.147.0 (default), 5 runs, 2026-08-17. The question asks for a recommendation without naming a vendor.

The Claude Code runs could read the operator instructions (CLAUDE.md). Those instructions request Polish, so some answers are in Polish. Results describe this setup, not an agent at your customer.
