Caddy
Web server written in Go that obtains and renews TLS certificates automatically, configured with a Caddyfile or a JSON API.
caddyserver.comrepositorydocsplugins
Caddy is a web server written in Go that is configured either with a Caddyfile, a plain-text format, or with JSON sent to its API. It obtains and renews TLS certificates for the sites it serves on its own, so a site behind Caddy needs no separate certificate tool to stay on HTTPS. Extensions are called modules, and the docs site keeps a directory of them.
Worth knowing
The homepage says Caddy is free software that relies on sponsorships to survive.
