Core offering

Codethink provides expert software engineering consultancy teams that tackle system-level software problems across embedded devices and enterprise systems, covering firmware, drivers, board support, operating systems, libraries, middleware and build tooling. The firm complements these services with proprietary and open-source products such as CTRL OS (a trustable, reproducible Linux-based OS for safety-critical use), the Trustable Software Framework (TSF), the Software Integration Factory, Testing in a Box, QAD/QAnvas, and BuildGrid/BuildBox.

Product overview

Codethink offers a portfolio of products centred on trustable, safety-critical software. The core product is CTRL OS (Codethink Trustable Reproducible Linux), a reproducible Linux-based operating system designed for automotive and industrial applications requiring functional safety certification. CTRL OS is developed using the Trustable Software Framework (TSF), an open engineering methodology that maps to international safety standards including IEC 61508, ISO 26262, and others. The Software Integration Factory provides standardised tooling for producing high-integrity software at scale. Supporting this portfolio, Codethink develops and maintains open-source build infrastructure tools including BuildGrid, BuildBox, QAD (Quality Assurance Daemon), and Testing in a Box for automated hardware testing.
