Overview
A certificate authority that provides free TLS certificates.
Definition
A certificate authority that provides free TLS certificates.
Real-world example
Let's Encrypt issues a free 90-day certificate for your domain; Caddy renews it automatically before expiry.
Common mistake
Hitting rate limits by deleting and re-adding the same domain dozens of times in one day during testing.
Better-PaaS in practice
Certificates are managed through Caddy. Check DNS, ports 80/443, and app health if issuance fails.
FAQ
Is Let's Encrypt only relevant to Better-PaaS?
No. Let's Encrypt appears across Docker, cloud platforms, and self-hosted tooling. Better-PaaS exposes the concept in deploy logs, dashboard fields, or docs when it affects your app.
