Bluefruit Software vs Timesys: overview

Bluefruit Software

Testing is the main reason buyers pick Bluefruit Software. The Redruth, Cornwall company has worked on embedded software since 2000, became employee-owned through an Employee Ownership Trust in 2019, and applies a Lean-Agile process with unit tests and test automation built in from the first sprint. It reports work on more than 100 products (per company website; independently unverifiable), with medical devices, scientific instruments and industrial equipment making up much of the portfolio. In 2023 it had about 75 staff and was hiring.

Timesys

Timesys came out of Pittsburgh in the mid-1990s, with founders tied to Carnegie Mellon University, and shipped one of the first real-time embedded Linux distributions. Its business now combines engineering services for open-source embedded software with Vigiles, a tool that tracks vulnerabilities in device software bills of materials. Lynx Software Technologies acquired Timesys in December 2023 and said all Timesys products would remain supported. The firm suits Linux-based devices that have to meet the security and SBOM rules arriving in the US and EU.
