Mongoose is a two-file C networking library and embedded web server providing HTTP, WebSocket, MQTT, TLS 1.3, and an optional built-in TCP/IP stack for microcontrollers and desktop OSes. It also includes firmware OTA update support and device-dashboard infrastructure for IoT products.
Use cases
- embed an HTTP server in firmware on ESP32 or STM32
- add MQTT telemetry to an IoT device
- serve a real-time device dashboard with WebSockets from a microcontroller
- implement firmware OTA updates over HTTP or MQTT
- add TLS 1.3 encrypted endpoints to embedded C code
- run a lightweight web server on Linux or Windows with a tiny footprint
- unify networking code across desktop and embedded targets
When to choose
- you need a small, dependency-free C/C++ networking stack for embedded or IoT devices
- you want HTTP, WebSocket, MQTT, and TLS in one integrated library
- you need OTA firmware updates and device dashboards on microcontrollers
- you want battle-tested code with commercial support and CRA compliance
When to avoid
- you need a full-featured general-purpose web server for hosting websites
- your project cannot accept GPLv2 or a commercial license
- you work in a language other than C/C++
- you need high-level async frameworks or rich middleware ecosystems
