The original title is: "Catch expiring TLS certs and weak security headers in CI — with one small CLI"

Short summary

Secably is a lightweight, dependency-light CLI that checks TLS certificate expiration, HTTP security header grades, DNS posture, and subdomains from the terminal or CI pipelines. A ready-made GitHub Action fails builds when certs near expiry or header grades drop below a configurable threshold, running entirely on your runner with no third-party data transmission. The core checks are open source and require no account, while a hosted side offers continuous monitoring with alerts.

• •CLI checks TLS cert expiry, security headers, DNS posture, and subdomains locally with zero core dependencies
• •GitHub Action fails CI on cert expiry within N days or header grade below threshold
• •Open source CLI and Action; hosted monitoring available as a paid complement
