dutctl is a command-line utility and service ecosystem for managing test devices in open-source firmware development environments. By providing a unified interface to interact with development boards across different platforms, dutctl eliminates the fragmentation of device management tools that has long plagued firmware development workflows. The project features remote device control, command streaming, multi-architecture testing, and a flexible plugin architecture for extensibility. Designed for firmware developers, QA teams, and CI/CD pipelines, dutctl simplifies complex device interactions through intuitive commands and comprehensive documentation. The platform supports both local and remote device management through its agent-server architecture, enabling efficient collaboration in distributed teams. With per-commit testing capabilities across multiple architectures, dutctl ensures high-quality firmware releases. We invite the open-source firmware community to try dutctl, contribute to its growth, and help shape its future development of advanced features like automated test sequencing and expanded hardware support.
