Monitor SSL certificates across your whole fleet
Add your domains and CertFleet keeps watch — re-probing the live certificate on a schedule and alerting you well before expiry.
CertFleet is single-purpose: SSL/TLS certificate monitoring is the whole job, so it's simpler and cheaper than bolting cert checks onto an observability platform.
Each domain is probed for its real served certificate and cross-referenced against Certificate Transparency logs for new issuance.
Alerts fire on email, Slack and webhooks at staged thresholds. The REST API and webhooks are available from the entry tier.
5 certificates are free forever — the most generous free tier in the category.
CertFleet probes the live certificate, watches Certificate Transparency, and alerts you 30/14/7/1 days before expiry. Free for 5 certificates, no card.
