## What it is
CertMate is a self-hosted certificate lifecycle management platform that issues and renews TLS certificates via ACME/Let's Encrypt across 29 DNS providers, discovers certificates it did not issue, maintains a certificate inventory, and deploys renewed certificates. It includes a private CA for internal names, a tamper-evident audit trail, OIDC/SSO with RBAC, a REST API with Swagger docs, a CLI, and multiple secret storage backends (Vault, AWS Secrets Manager, Azure Key Vault).

## Use cases
- automate ssl certificate issuance and renewal across multiple dns providers
- self-hosted lets encrypt certificate management with rest api
- discover and inventory tls certificates across my infrastructure
- run a private certificate authority for internal domain names
- deploy renewed certificates automatically to servers
- centralized certificate expiry monitoring and audit trail
- manage acme dns-01 challenges for cloudflare route53 azure dns

## When to choose
- you need centralized, self-hosted TLS certificate lifecycle management with an API and CLI
- you want certificate discovery and inventory across a multi-provider DNS estate
- you need a private CA for internal names alongside public ACME certificates
- compliance requirements (e.g., NIS2) demand a tamper-evident audit trail and RBAC/SSO

## When to avoid
- you only manage one or two certificates where a simple certbot/caddy setup suffices
- you need a GUI-first certificate manager rather than an API-centric service
- you cannot run a persistent self-hosted service or Docker container
