About
Kestrel is an open-source, cross-platform web server for 
ASP.NET Core that can serve HTTP requests on Windows, 
Linux, and macOS.
It uses an event-driven, high-performance architecture to handle many concurrent connections, supports HTTP/1.1, 
HTTP/2, HTTP/3, and 
WebSockets, provides HTTPS support, and integrates closely with the ASP.NET Core middleware pipeline and configuration system.
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.
