acmetool is a command-line tool for automatically acquiring and renewing TLS certificates from ACME servers such as Let's Encrypt. It works like 'make' over a simple state directory, is idempotent, and integrates with any webserver without modifying its configuration.

Use cases

• automatically obtain let's encrypt certificates
• renew ssl certificates on a cron job
• get tls certs without modifying webserver config
• self-host https with automatic certificate renewal
• manage acme certificates for multiple domains
• redirect http to https with built-in responder

When to choose

• you want a single dependency-free binary for ACME certificate management
• you need zero-downtime automatic renewal with any webserver
• you prefer transparent, documented flat-file state over client-managed config
• you want an idempotent, fully scriptable certificate tool

When to avoid

• you want a client that automatically configures nginx or apache for you
• you need GUI-based certificate management
• you require frequent new features or active development, as releases have slowed
