Built for apps on Replit, Lovable and other AI app builders. Enter your domain and we check it and its www twin, the way a visitor's browser reaches them.
The A, AAAA and CNAME records for both names, and whether www points anywhere at all.
Whether there is one, whether it covers the name, who issued it, and how many days it has left.
www not linked, a certificate still pending, the two names pointing at different hosts, a Cloudflare proxy in the way, and missing verification records.
The checker only looks at the domain you enter and its www twin. It opens one secure connection to each name to read its certificate, and only when it cannot read one that way does it send a single HEAD request to the home page. Nothing you enter is stored. Behind Cloudflare's proxy it can only see Cloudflare's certificate, and it says so. Stuck on a broken launch? See fixing a Replit app or fixing a Lovable app.
