vs Mozilla Observatory
SafeToShip vs Mozilla Observatory: full security vs HTTP headers
Observatory for an A+ on headers. SafeToShip for everything beyond headers.
Mozilla Observatory is the gold standard for HTTP header analysis. It is free, fast, accurate, and well-explained — we recommend everyone run it. The catch: it only checks HTTP response headers. SafeToShip starts where Observatory stops: bundle secrets, Supabase RLS, Firebase rules, CORS misconfig, cookie flags, exposed files, and email DNS.
