# nasa/fprime

> 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.

- Magnitude: 1.0 out of 10 — Steady

## 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

## Why it’s here

- 0 stars so far today, about 2 expected by the end of the day.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
