ACME vs REST API

ACME is the CA protocol. A REST API like sslcertificates.io orchestrates ACME plus inventory, webhooks and team access.

Answer first

ACME is the CA protocol. A REST API like sslcertificates.io orchestrates ACME plus inventory, webhooks and team access.

Tradeoffs

Pick the control you need: validation depth, wildcard support, key custody, or operational tempo. Encryption strength is not the differentiator in these comparisons.

What this platform does

One request shape for inventory, orders, webhooks and optional deploy targets. Multi-CA is an explicit provider field — not automatic failover after a challenge is published.

What we will not claim

No official partnership. No “winner.” No encryption-strength ranking. Commercial CA prices come from your contract with that CA. Sources: CA documentation and CA/Browser Forum Baseline Requirements.
