TLS Monitor

Monitor TLS certificate expiry for HTTPS endpoints from SuperPlane — add hostnames, check certificates on a schedule, and see status at a glance in the console.

Built with SuperPlane.

How it works

1. Add endpoint — register a hostname in memory (pending)
2. Check TLS — connect on port 443, read the certificate, and classify expiry (healthy, warning, outdated, or invalid)
3. Update results — store status, last_check, and expires_in_days in the tlsEndpoints memory namespace
4. Schedule — re-check every monitored endpoint every hour
5. Console — endpoint table with per-row check and delete actions, plus bulk Run checks now
