Mongoose Web Server

Mongoose is a two-file C networking library for microcontrollers that combines TCP/IP, HTTP, WebSocket, MQTT, TLS, OTA, and device-dashboard infrastructure. Build production-ready browser UIs without stitching TCP/IP stack, web servers, TLS, frontend code, and firmware glue together. Mongoose is extremely cross-platform, running on STM32, ESP32, NXP, RP2040/RP2350, Renesas, Microchip, Embedded Linux, desktop Windows/Linux/MacOS, and many other architectures. It includes a built-in TCP/IP stack, embedded web server, WebSocket support, MQTT, TLS security, and dashboard infrastructure in a single event-driven framework. Mongoose is dual-licensed under GPLv2 and commercial, making it suitable for evaluation, prototyping, and production deployment.
