// OPEN SOURCE VS HOSTED
SSL certificate monitoring: open source vs hosted
Rolling your own with openssl, cron and a notifier works — until it silently breaks. CertFleet gives you the same checks without the maintenance.
DIY scripts (openssl s_client + cron + a Slack curl) are a great weekend project and a fragile production dependency.
CertFleet runs the probe + Certificate Transparency loop for you, with staged alerts, history and a dashboard.
You keep the developer ergonomics — REST API, signed webhooks — without owning the cron host or the alerting glue.
Free for 5 certificates, so you can replace your script today.
