Migration guide

Switching from Oh Dear?

DomainCare runs the same per-site, all-features-included pricing model that makes Oh Dear easy to reason about. The differences: deeper email deliverability (full SPF + DKIM + DMARC + BIMI parsing, not just presence checks), security-headers grading, daily dangerous-port scanning, passive CMS fingerprinting, and a real 30-day free trial without a payment method.

Honest take

Oh Dear is a good product — the cleanest UI in this space after Better Stack, an EU-hosted GDPR-friendly stance, and a per-site pricing model that doesn't penalize you for adding checks. We borrowed the per-site model from them. The places where DomainCare wins are specifically (a) email deliverability depth, (b) the vulnerability surface (security headers, port scanning, CMS detection), and (c) a free trial that doesn't require a credit card. If you don't care about those, Oh Dear is fine.
