TokenTimer is an open-source certificate lifecycle automation and expiration management platform for DevOps, SRE, platform engineering, security and IT teams.

It centralizes TLS certificates, API keys, secrets, licenses, subscriptions and other expiring infrastructure assets with ownership, proactive alerts, integrations and audit history.

TokenTimer CertOps automates certificate renewal, deployment, service reload and verification through customer-controlled infrastructure. Private keys remain outside the TokenTimer control plane.

TokenTimer Core is AGPL-3.0 and supports self-hosted deployments with Docker Compose and Kubernetes/Helm.
