Is the ZeroSSL Worth It?

Best free option with a dashboard. ZeroSSL is the pick when you want free certificates but also want to see them all in one place and be told before they expire. Beyond three certificates it starts costing real money.

ZeroSSL Pros & Cons

Pros
  • Free certificates with a real management dashboard and expiry alerts
  • ACME-compatible, so existing Certbot setups can point at it
  • One-year certificates on paid plans — fewer renewals to manage
  • Simple browser-based issuance for people without shell access
Cons
  • Free tier is capped at three certificates
  • Wildcards need the $50 Premium plan
  • DV only; no organisation validation
