## What it is
Certimate is a free, open-source, self-hosted ACME tool for managing SSL/TLS certificates with a visual web UI. It automates the full certificate lifecycle - issuance, deployment to 150+ destinations, renewal, and expiration monitoring - across 70+ DNS providers and multiple ACME CAs.

## Use cases
- automatically renew Let's Encrypt certificates before they expire
- issue wildcard SSL certificates for my domains
- deploy SSL certificates to CDN, load balancers, or Kubernetes
- self-hosted alternative to certbot with a web UI
- manage certificates across multiple cloud providers like Cloudflare, AWS, Alibaba Cloud
- get notified when certificates are about to expire
- automate HTTPS certificate issuance and deployment for my servers

## When to choose
- you want a self-hosted, privacy-friendly certificate manager where all data stays on your servers
- you need automated certificate issuance and deployment across many registrars and deployment targets
- you prefer a visual workflow over writing certbot scripts or hooks
- you want a lightweight zero-dependency tool (~16 MB memory) with no database to install

## When to avoid
- you need a managed SaaS certificate service - Certimate is self-hosted only
- you only need a simple CLI one-shot certificate fetch and prefer certbot or lego directly
- you require a CA or certificate authority of your own rather than an ACME client
