Mongoose Web Server

Have you ever struggled with any of this?

Modifying an SDK example is challenging. Without expert frontend skills, the UI becomes flaky and looks unprofessional. The full firmware requires additional libraries for WebSocket, MQTT, and JSON, further complicating the code.

A simple SDK example works, but production code exposes issues deep within the stack. The network driver gets stuck, and implementing smooth firmware updates takes months, yet still doesn't function as it should.

The UI over HTTPS takes several seconds to load, and the entire system consumes too much RAM. Tuning TLS speed and RAM usage takes weeks, with little success finding help on forums or through vendor support.

Here is a simple 2-step solution!

1. Use the wizard to build your project on your target hardware

Mongoose Wizard is a no-code visual tool that enables you to build your Web UI and REST API without writing any frontend code. You can choose your target hardware, such as STM32, ESP32, NXP, or embedded Linux/Windows, and select your preferred environment - whether it's bare metal or an RTOS like FreeRTOS. Additionally, you choose a target IDE, such as CubeIDE, MCUXpresso, or make + GCC.

2. License the Mongoose Library

Mongoose Wizard builds projects on top of the open-source Mongoose Library, which has been in development since 2004. The Mongoose Library, with over 11k stars on GitHub, is used by thousands of companies, both large and small. It is licensed under a dual license: GPLv2 and commercial. If your project is open source, the Mongoose Library is free to use. For other projects, a commercial license is required - fill out this form to receive a license quotation today.

What is included in the package

Professional look and feel

With Mongoose Wizard, you can create a professional-looking interface without any design or frontend skills.

User login support

User authentication with multiple access levels is enabled with a single checkbox.

UI auto-refresh

Always ensure that your dashboard is up-to-date with the device connection indicator on the toolbar.

Easy to attach UI controls to the device hardware

Panels with dropdowns, toggles, and inputs can be mapped to C structures. All you need to do is adjust the getter and setter C functions.

Conditional display

Use conditional display to show device data that exceeds thresholds with an alternative style.

Built-in firmware updates

For many microcontrollers, such as STM32, ESP32, MIMXRT, and others, Mongoose provides built-in firmware update support. You don't need to do anything - it just works.

Cross-platform code

The generated networking code is truly cross-platform. Whether you choose GCC + make, CubeIDE, Zephyr, Linux, macOS, MCUXpresso, or Windows, the choice is yours.

TLS 1.3 built-in, enabled by default

Typically TLS is a burden, but not with Mongoose. Enjoy fast handshakes (<1s) and minimal RAM usage (few Kb per connection).

Tiny flash and RAM footprint

Default dashboard UI takes about 55k of flash, Mongoose code (with TLS!) takes less than 80k of flash, and each connection uses few Kb of RAM.

What our customers say

Still unsure if the Mongoose Library is the right choice for you? It runs on International Space Station - if it works for NASA, it will probably work for you too!

Easily, Mongoose is one of the best web servers on the market. Mongoose has helped us to achieve the required level of performance with the seamless integration. It is very stable and we have not encountered any significant bugs.

Santhosh Kumar P.B.
Lead Architect, Schneider Electric (France)

Mongoose Library is well documented, well supported, stable and full of features. It has a proven track record, obvious ongoing updates and enhancements, and functionality. After testing Mongoose and exploring the features it was the clear winner. Integration was straightforward and took a matter of days. The support and response time for any queries was outstanding.

Tony Gaunce
Principal Engineer, Broadcom Inc. (USA)

Mongoose Library was the only product which fulfilled our requirements at reasonable cost, and the possibility to get a support contract was an advantage for us. Our experience was good enough to influence another development team in Pilz to use Mongoose Library. Since Mongoose is an open source product it could be reviewed and analyzed by a board community which helps to improve the security.

Frank Eberle
Software Developer, Pilz GmbH (Germany)

If you are debating which library to use, don't make our mistake and try something else, as Mongoose Web Server Library does exactly what it needs to do. We started with a different C++ library that seemed like it would be easier to use, but it was riddled with bugs that made it unusable for our purposes. All the issues we had with the other library were solved with Mongoose. Mongoose was very straightforward to implement and we didn't have any issues integrating it.

Chad Slater
VP of Research & Development, Extensis (USA)

We have exclusively used the Mongoose web server since 2012 and we have never regretted the decision. The Mongoose Web Server is a great embedded product to use in your application to expand its current web feature set. Mongoose also has great stability and is maintained to keep up with the current and future marketplace demands of an embedded web server
