What it really isZeroSSL — SSL/TLS certificate authority with free and paid certificate management.
Our takeZeroSSL is a full certificate authority offering free 90-day TLS certificates via ACME or a web dashboard, plus paid plans with annual certs, wildcards, and priority support.
It has a permanent free tier requiring no credit card. It competes directly with Let's Encrypt but adds a visual dashboard that lowers the barrier for non-CLI users.
Why we rate itZeroSSL democratises TLS by offering a genuinely free, no-card-required certificate tier with a clean dashboard — a meaningful UX improvement over Let's Encrypt's CLI-only flow.
Paid tiers are reasonably priced for teams that need annual certificates and audit logs.
The catchFree tier certs expire every 90 days requiring renewal automation; no warranty on free certs makes them unsuitable for e-commerce compliance needs.
Paid tiers can get expensive at scale compared to cloud-provider-bundled TLS.

Best / not good for

Best for
  • IT admins wanting GUI-managed free TLS certificates
  • Developers automating certificate issuance via ACME/REST API
  • SMBs needing annual wildcard SSL without Let's Encrypt CLI complexity
Not good for
  • E-commerce sites requiring warranty-backed certificates on a budget
  • Teams already using cloud-native TLS (AWS ACM, Cloudflare, etc.)
  • Enterprises needing OV/EV certificates with legal entity validation
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: free cert issued in under 5 minutes via dashboard; ACME automation setup takes 15–30 min.
  2. Scale breakpoint
    Per-plan pricing jumps steeply — Platinum at $169.99/mo still has cert-count caps; large fleets need Enterprise.
  3. Walled garden
    Low: certificates are standard X.509; ACME protocol is open; exports in standard PEM/PFX formats.
Still a fit?
If none of these block you, start on the free plan.
