🆚 Caddy vs. OpenResty

Caddy is an open-source multi-platform web server written in Go with built-in support for automatic HTTPS and modern web protocols.

It supports automatic TLS management with providers such as Let's Encrypt and ZeroSSL, includes a built-in reverse proxy with load balancing, offers configuration through the human-readable Caddyfile or a JSON-based REST API, and features a modular architecture that can be extended with plugins.

OpenResty is an Nginx distribution that bundles the LuaJIT interpreter to run Lua scripts directly inside the web server.

It embeds Lua, a lightweight scripting language, into Nginx's event-driven architecture, enabling high-performance dynamic request handling, asynchronous I/O, API and microservice development, traffic control, caching, authentication, and logging.
