Leading Zephyr® RTOS Expertise: From Core Contributions to Commercial Success

Croxel is a member of the Zephyr Project. As core contributors with a voice in its technical direction, we help companies and engineering teams bring products built on Zephyr to market.

Why Zephyr?

Zephyr has been at the core of how we build connected products for years, because we believe it is the strongest foundation for connected embedded products:

  • Vendor-neutral
  • Broad hardware support
  • Open governance under The Linux Foundation®
  • Long-term support releases you can plan around

Croxel has now joined the Zephyr Project as an official member to give back and strengthen our ties to the project.
