Overview

Quick TLS certificate info and monitoring via TLSentinel.

TLSentinel brings your self-hosted TLS certificate monitoring directly into Chrome. When you visit any HTTPS site, the extension queries your TLSentinel instance in real-time to fetch the live certificate and tell you exactly when it expires — no cached data, no guessing. The badge on the extension icon gives you an at-a-glance status for every page you visit. Features: - Live certificate lookup for any HTTPS site - Color-coded badge: green (valid), amber (expiring soon), red (critical / expired) - See common name, issuer, and expiry date at a glance - Know instantly whether a site is already being monitored - Add unmonitored sites to TLSentinel with one click - Jump directly to the endpoint detail page in your TLSentinel dashboard Requirements: TLSentinel is a self-hosted TLS certificate monitoring platform. You will need a running TLSentinel instance and an API key to use this extension.
