What does this HTTP Caddy feature in OpenServer 6.5.0 mean? How is it different from Apache or Nginx?

[OSPanel]

Caddy in OpenServer 6.5.0 means OpenServer can use the Caddy web server to serve your local sites (virtual hosts), handle HTTP requests, serve static files, and forward PHP requests (typically via PHP‑FCGI). Functionally, it plays the same core role as Apache or Nginx.

How Caddy differs from Apache or Nginx

• Simpler configuration: Caddy’s Caddyfile is usually shorter and easier to read than Apache/Nginx configs.
• Automatic HTTPS (Caddy’s headline feature): Caddy can automatically obtain and renew TLS certificates (Let’s Encrypt) and enable HTTPS by default.
  Note: in a purely local/dev setup this may depend on domain/access constraints; sometimes self-signed or internal cert modes are used.
• Modern defaults: strong support for HTTP/2 and HTTP/3 (QUIC) when configured.
• Modular design: Caddy is plugin-friendly and focuses on secure, sensible defaults.

Role comparison

• Apache: great .htaccess support and per-directory overrides; very flexible but can be heavier/more complex.
• Nginx: extremely common for high-performance static serving and reverse proxying; configuration can be more verbose/less intuitive.
• Caddy: optimized for “easy to set up and just works,” especially for HTTPS and reverse proxy use cases.

Bottom line: “Caddy” in OpenServer means you can select Caddy as your web server instead of Apache/Nginx; it mainly differs in ease of configuration and its built-in automation around HTTPS and modern protocol support.
