Certbot

Certbot — EFFs free tool to automatically obtain and renew Lets Encrypt TLS certificates.

-

Our Verdict

The default way to automate Let's Encrypt on a single host; less ideal once you're juggling dozens.

Pros

  • Free TLS certs via Let's Encrypt automation
  • Auto-renewal with cron or systemd timers
  • Wide plugin support: Nginx, Apache, DNS
  • Battle-tested on millions of servers

Cons

  • CLI-centric, awkward for large fleets
  • 90-day certs require reliable renewal jobs
  • Rate limits hurt during misconfigured retries
  • No built-in cert inventory or dashboard
Best for: Admins running a handful of Linux servers needing free, renewable TLS. Not for: Enterprises needing centralized cert lifecycle management across thousands of endpoints.

When to Use Certbot

Good fit if you need

  • Auto-renewal of Let's Encrypt TLS certs via cron
  • Wildcard certificate issuance with DNS-01 ACME challenge
  • HTTPS enforcement for self-hosted web applications
