Certbot
Pros
- + Free, Apache 2.0, EFF-maintained — no paid tier or usage caps
- + Automates issuance, installation, and renewal for Apache, Nginx, HAProxy, Plesk, standalone, webroot
- + Wildcard certificates via DNS-01 with many first-party DNS provider plugins
- + Works with any ACME CA, not just Let's Encrypt
- + Interactive instruction generator makes correct setup reachable for non-specialists
Cons
- - Assumes root access on a traditional server; poor fit for containers and serverless
- - Renewal failures are silent unless you add monitoring and alerting
- - Config-parsing plugins can refuse complex setups, falling back to manual work
- - Certificates-only scope: no inventory, policy, or contractual support
Let's Encrypt

- + Huge client ecosystem (Certbot, acme.sh, Caddy, Traefik, control panels)
Cons
- - Domain validation only — no OV or EV certificates
- - 90-day lifetimes (64 days from February 2027) make automation mandatory
- - No support SLA or contractual recourse; community forum only
