acme.sh
Pros
- + Free GPLv3 tool with no runtime dependencies beyond a POSIX shell — runs on servers, routers, NAS boxes, and containers alike
- + Broadest DNS-01 provider coverage of any ACME client, plus DNS alias and stateless modes for awkward zones
- + Wildcard, SAN, RSA and ECDSA (default) certificates with HTTP-01, DNS-01 and TLS-ALPN-01 challenge support
- + Multi-CA support (Let's Encrypt, ZeroSSL default, Google Trust Services, SSL.com, Actalis) with a single --server flag
- + Self-installing daily renewal cron and deploy hooks with service reload commands — automation once configured
Cons
- - No support contract, no SLA, and community-only help (wiki, GitHub issues, Gitter) when renewals break
- - Learning curve beyond the basic case: shell flags, environment credentials, DNS propagation behavior
- - DNS API tokens stored on the renewing host are a standing credential — scoping and protecting them is on you
- - GPLv3 copyleft complicates embedding in closed commercial products
- - High maintainer concentration and the curl|sh install idiom warrant release pinning and verification in production
SSL.com
Pros
- + List prices well below the enterprise CAs across DV, OV, EV, wildcard, and UCC/SAN
- + Complete validation range with strong warranties (up to $1,750,000 on Enterprise EV)
- + Automation-first: ACME protocol/API, certificate lifecycle management, unlimited reissues and server licences
- + eSigner cloud signing for EV code and document signing without hardware tokens
- + US-based 24/7 support, WebTrust audits, CA/Browser Forum voting member; free 90-day DV trial
Cons
- - Smaller brand recognition than DigiCert/GlobalSign with auditors and procurement
- - Limited one-click integration with some hosting panels — manual installation may be needed
- - Promo/multi-year pricing is hard to pin down without a written quote
- - Sprawling product catalogue (TLS, code signing, S/MIME, VMC, C2PA, Matter certs) can overwhelm simple buyers
- - EV validation inherently takes 1-5 business days; limited professional-services arm for complex PKI
