A flight-proven, component-driven framework for rapid development of spaceflight and embedded software applications.
F´ (F Prime) is an open-source flight software and embedded systems framework developed at NASA's Jet Propulsion Laboratory. It provides a component-driven architecture and tools for rapidly building reliable software for space applications like CubeSats and instruments. The framework includes a C++ core, modeling tools for automatic code generation, and testing utilities to ensure robustness in critical environments.
Embedded systems engineers and software developers working on spaceflight missions, CubeSats, SmallSats, instruments, or other safety-critical real-time applications. It's particularly suited for teams needing a proven, modular framework for flight software.
Developers choose F´ for its flight-proven reliability, component-driven modularity that speeds development, and comprehensive tooling including modeling and testing. As a NASA-developed open-source framework, it offers a trusted foundation for critical embedded systems without vendor lock-in.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Has been successfully deployed on several space applications, providing a trusted foundation for critical systems, as evidenced by the list of projects on the F´ website.
Decomposes software into discrete components with well-defined interfaces, enabling maintainable and testable embedded systems, a core feature highlighted in the README.
Includes modeling tools for specifying components and connections that automatically generate code, accelerating development as described in the key features.
Supports unit and integration testing to ensure software reliability, which is essential for safety-critical applications like spaceflight.
Requires deep familiarity with C++, embedded systems, and NASA-specific tooling, making it less accessible for teams without aerospace or complex embedded experience.
Depends on specific system requirements like Python 3.9+, Clang or GCC compilers, and virtual environments, which can hinder quick adoption and increase initial setup time.
Primarily C++-focused with no native support for alternative embedded languages, restricting flexibility for projects using diverse tech stacks.
