Mongoose - Embedded Web Server / Embedded Networking Library

Mongoose is a network library for C/C++. It implements event-driven non-blocking APIs for TCP, UDP, HTTP, WebSocket, MQTT. It is designed for connecting devices and bringing them online. On the market since 2004, used by vast number of open source and commercial products - it even runs on the International Space Station! Mongoose makes embedded network programming fast, robust, and easy. Features include:

Cross-platform:
- works on Linux/UNIX, MacOS, Windows, Android
- works on STM32, NXP, ESP32, NRF52, TI, Microchip, and other
- write code once - and it'll work everywhere
- ideal for the unification of the network infrastructure code across company
Built-in protocols: plain TCP/UDP, SNTP, HTTP, MQTT, Websocket
SSL/TLS support: mbedTLS, OpenSSL or custom (via API)
Asynchronous DNS resolver
Tiny static and run-time footprint
Source code is both ISO C and ISO C++ compliant
Very easy to integrate: just copy mongoose.c and mongoose.h files to your source tree. See exact steps
Works with any network stack with socket API, like LwIP or FreeRTOS-Plus-TCP
Built-in TCP/IP stack with drivers for bare metal or RTOS systems
- Available drivers: STM32 F4, F7, H5, H7; NXP RT1020; TI TM4C; Microchip SAME54; Wiznet W5500
- A complete Web device dashboard on bare metal Nucleo-F429ZI is only 6 files
- For comparison, a CubeIDE generated HTTP example is 400+ files
Built-in firmware updates for STM32H5, STM32H7, and more coming
Detailed user guide, API reference and tons of tutorials available

Security

We take security seriously:

Mongoose repository runs a continuous integration test powered by GitHub, which runs through hundreds of unit tests on every commit to the repository. Our unit tests are built with modern address sanitizer technologies, which help to find security vulnerabilities early
Mongoose repository is integrated into Google's oss-fuzz continuous fuzzer which scans for potential vulnerabilities continuously
We receive periodic vulnerability reports from the independent security groups like Cisco Talos, Microsoft Security Response Center, MITRE Corporation, Compass Security and others. In case of the vulnerability found, we act according to the industry best practice: hold on to the publication, fix the software and notify all our customers that have an appropriate subscription
Some of our customers (for example NASA) have specific security requirements and run independent security audits, of which we get notified and in case of any issue, act similar to (3).
