Certify The Web vs Smallstep Certificate Manager

Certify The Web provides products for requesting, deploying, and renewing TLS certificates. Certificate Manager is intended for Windows servers or desktops, Management Agent for headless Linux and macOS systems, and Management Hub for central administration of multiple instances. The tools support ACME authorities including Let's Encrypt, Google Trust Services, ZeroSSL, Actalis, and private or enterprise CAs. Domain checks can use HTTP or DNS, with options ranging from built-in providers and Certify DNS to manual TXT records or custom scripts. Deployment tasks cover IIS, Apache, nginx, Tomcat, Exchange, ADFS, RDP, Azure App Service, Azure Key Vault, HashiCorp Vault, and IIS Centralized Certificate Store. Other deployments can use scripts, webhooks, SSH/SFTP, or UNC shares. Hub offers a web interface, API, role-based access, managed DNS challenges, and certificate monitoring across instances. A free evaluation has no feature limits or time limit. Cloud-managed licensing starts at $4.99 a month per install; other plans have annual or longer billing terms. Licenses do not bypass certificate authority rate limits.
