About the project

F´ (F Prime) is a component-driven framework for flight software and embedded systems, originally developed at JPL and flown on space missions. Suited to CubeSats, SmallSats and instruments, it provides a component architecture, a C++ core, modeling tools and testing support.

Useful for

Bootstrap a flight software project with fprime-bootstrap and build it from ready-made components
Model components and connections and generate C++ code from them
Test flight software at unit and integration levels with built-in tools

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
