What is certimate?

A workflow automation platform — connect hundreds of apps and automate repetitive tasks without writing code.

Main components

• Flexible workflow orchestration, fully automation from certificate application to deployment.
• Supports requesting single/multiple/wildcard domain certificates, IP address certificates, with options for RSA or ECC key.
• Supports DNS-01 challenge and HTTP-01 challenge both.
• Supports various certificate formats such as PEM, PFX, JKS.
• Supports more than 70+ domain registrars (e.g., AWS, Cloudflare, GoDaddy, Alibaba Cloud, Tencent Cloud, etc. Check out full providers).
• Supports more than 160+ deployment destinations (e.g., Kubernetes, CDN, WAF, load balancers, etc. Check out full providers).
• Supports multiple notification channels including email, Discord, Slack, Telegram, DingTalk, Feishu, WeCom, and more.
• Supports multiple ACME CAs including Let's Encrypt, Actalis, Google Trust Services, SSL.com, ZeroSSL, and more.

The biggest strength is turning manual chores into scalable workflows — saving hours of work per week.
