We are an open-source grassroots community gathering companies, academia, and hobbyists, distributed all around the world, to build a better IoT.
RIOT is developed by an open community that anyone is welcome to join. Decisions in the RIOT community are driven by rough consensus, similar to the IETF. We have a Code of Conduct to make the social behavoir we value clear.
Project roots. The seed for RIOT was FeuerWare, an operating system for Wireless Sensor Networks. It was part of the FeuerWhere project where firefighters should be monitored. Major design goals were reliability and real-time guarantees.
Towards Internet compliance. To increase modularity and include new IETF protocols, µkleos was forked from the orignal FeuerWare repository. Support for 6LoWPAN, RPL, and TCP was integrated over the following years.
RIOT goes public, founded by Freie Universität Berlin, INRIA, and HAW Hamburg. RIOT is the direct successor of µkleos. We decided on re-branding to avoid problems with spelling and pronouncing the name of the operating system. We explicitly promote RIOT to a larger community.
The RIOT community is growing. To bring RIOTers together, we organized the first RIOT Summit, which accommodated plenary talks, hands-on tutorials, and demos, as well as lively discussions. Since then, the RIOT Summit takes place yearly.
After nine releases since 2013, we moved to a quarterly release cycle.

Acknowledgments and Contact
To the original authors of FeuerWare, the members of the research projects AVS Extrem, G-Mesh-Lab, OPNEX, SAFEST, and VIVE, and anybody else who has contributed to FeuerWare, µkleos, and RIOT. Furthermore, a special thank goes to Peter Schmerzl!
Many people are working on RIOT. Public development questions should be directed to the RIOT forum. If you require one-to-one communication for other development questions, you can contact the RIOT maintainers, and for questions related to formal project establishment or collaboration, you can contact Emmanuel Baccelli, Thomas Schmidt, and Matthias Wählisch.
RIOT in the wild
We use RIOT in our after-market product for connected car-sharing. RIOT's modular architecture helped us a lot to address the multiple challenges we faced, to design software and networking embedded on a low-power 32-bit microcontroller. Also, RIOT is fun to tinker with, and the RIOT community is very open minded!

In Locha Mesh, we decided to use RIOT for a variety of reasons, including an active community surrounding it, the overall design of the Operating System that's coupled with a powerful and extensible network stack, and the support for a good variety of CPUs and boards.

At Sapienza University of Rome, we train our computer engineer students based on RIOT to gain practical skills and knowledge about the IoT. The wide range of tools and experimentation facilities for cross-layer debugging and profiling will be valuable for them when developing, testing, and evaluating IoT applications in future professions.

We chose RIOT in our products because of the excellent support of microcontrollers, boards, and peripherals. Our customers benefit from the modular architecture in RIOT, which enables easy customization.

At wolfSSL we love how easy it is to integrate all the components in the RIOT ecosystem, and the large selections of IoT targets supported. The wolfSSL TLS library and the wolfCrypt cryptography engine are available as built-in RIOT modules, distributed with a GPLv2 license.
