Live check · web & api
Recon Node runs around 30 checks against the page — status codes, TLS, security headers, broken links, meta tags, error handling — and reports what it finds. Run it twice and repeat findings collapse instead of piling up.
Standard: status, TLS, headers, links, meta. Runs in a few seconds.

We check each site every 15 minutes and email you if it goes down, comes back, or if its security headers or third-party scripts change.
