OpenResty is a web platform based on Nginx and LuaJIT. It extends Nginx with Lua scripting capabilities through various Lua modules and libraries. The platform enables developers to build high-performance web applications, APIs, and gateways using Lua within the Nginx ecosystem. Key components include the Nginx core, LuaJIT just-in-time compiler, and bundled Lua libraries like lua-resty-core and lua-resty-lrucache. Typical use cases include web application servers, API gateways, reverse proxies, and load balancers. Commercial support is available separately from the open-source project.
