Mongoose
Embedded networking stack with visual Web UI builder
Mongoose is an all-in-one embedded networking framework for
companies building TCP/IP-connected devices. It combines network
drivers, a TCP/IP stack, TLS 1.3, embedded web server, WebSocket,
MQTT, Modbus-TCP, firmware OTA updates - with Mongoose Wizard, a
visual Web UI builder that helps teams ship a professional device
dashboard without becoming frontend experts.

Mongoose vs vendor SDK examples
The typical alternative is taking vendor SDK networking examples (often
lwIP + FreeRTOS or Zephyr) and turning them into a product. It works
for a demo, then slows down: too many moving parts from different
vendors, mediocre UI, painful TLS integration, and hard-to-reproduce
field bugs.
| Mongoose | Vendor SDK examples |
|---|---|
| Integrated stack - drivers, TCP/IP, TLS, protocols, JSON, OTA | Fragmented parts to stitch together and maintain |
| Visual Web UI builder - professional dashboards without frontend build chains | DIY UI - HTML/JS tooling, assets, and hand-built pages |
| Fits existing firmware - works with lwIP, Zephyr, NetX, or standalone | Locked-in patterns from demo architecture |
| Developer-led support from the engineers who built the stack | Forums and samples, sometimes with no response |
| Security workflow - proactive fixes ahead of public CVEs | Varies by component and your integration |

Why Mongoose
All-in-one
Drivers, TCP/IP, TLS 1.3, Web server, WebSocket,
MQTT, Modbus-TCP, JSON, and firmware OTA in
two files
Mongoose Wizard
Visual Web UI builder that helps teams without frontend expertise
create professional device dashboards quickly.
Cross-platform
Runs everywhere - on popular microcontrollers and on desktop and mobile
platforms, letting teams reuse infrastructure across products
Fits your firmware
Works with lwIP, Zephyr, NetX, or standalone - under any RTOS or
bare metal - and fits your existing development environment.
Security & EU CRA compliance
Proactive security alerts with private fixes ahead of CVEs,
giving you time to patch before disclosure.
Firmware OTA updates
Built-in firmware OTA support so you do not have to invent and
validate your own update system.
Support by authors
Support is provided by the engineers who built the stack, from
drivers to protocols to Wizard. You're never alone.
Low footprint
Runs on 8-bit MCU with 6Kb of RAM! And perhaps can run
on your target hardware, too. No need to change.
Best in class
12.5k Github stars. Runs on ISS by NASA. Licensed by
hundreds of companies, big and small.
Mongoose is a reliable embedded web server and complete networking framework.
Licensing
Mongoose is dual-licensed: GPLv2 and
commercial. Use GPLv2 for evaluation and
prototyping. Choose a commercial license when shipping production
devices.
GPLv2 Open Source
Great for evaluation, prototypes, and learning. Explore the
repository and documentation to get started quickly.
Commercial licensing
For shipping proprietary firmware at scale, with developer-led
support and a security workflow aligned with production needs.
Embedded Web Server for IoT and Connected Devices
Mongoose is an embedded web server and TCP/IP stack for MCUs, RTOS, and bare metal platforms. With built-in HTTP, WebSocket, and REST capabilities, Mongoose serves UI and APIs on constrained devices. Mongoose includes TLS 1.3 stack and firmware OTA updates.
