certchime.com·Infrastructure & Backend

certchime provides real-time monitoring of SSL/TLS certificates for websites, focusing on instant feedback and expiry reminders. Users can check the status of a website's certificate simply by typing a domain, with results appearing immediately and indicating whether the certificate is safe, expiring soon, or at risk. This approach eliminates the need for sign-up, forms, or waiting, streamlining the process of certificate health checks.

The service performs direct TCP/TLS handshakes with each domain, ensuring that data is live and not cached. It does not require any installation, agents, or DNS changes, and operates entirely through the browser and certchime's servers. For those who prefer automation, certchime offers a curl-based API, allowing users to subscribe for expiry reminders by sending a simple command with their domain and email address.

Subscribers receive email notifications at 30, 14, 7, and 1 day before a certificate's expiry, with one email per stage to avoid unnecessary messages. The platform emphasizes privacy, ensuring that users' domains remain confidential and that checks are performed through direct connections without intermediaries.

certchime is available as a free service, and is designed for anyone needing to monitor website SSL/TLS certificates and avoid unexpected expirations.
