fprime-visual
F Prime Prime (FPP) model visualization tool
Decision gist · record as of 2026-08-14
Yes, if you are actively developing with F Prime and need a topology visualizer. The package is stable and has no known vulnerabilities, but maintenance is dormant—no updates since December 2023. Install it for visualization tasks within F Prime workflows, but do not expect bug fixes or feature updates. Verify compatibility with your F Prime Layout version before relying on it in production.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires F Prime Layout JSON files as input; the package reads topology data from .json files, not raw F Prime projects.
- Low install friction with a pure Python wheel distribution.
- Maintenance is dormant—last commit was 2023-12-15 with no activity since—but the package is marked Production/Stable and supports Python 3.8 through 3.12.

What it is and what it does
fprime-visual is a Flask-based web application that renders interactive topology diagrams for F Prime flight software and embedded systems. It reads JSON layout files generated by F Prime Layout and displays them in a browser with customizable themes, screenshot capture, and canvas editing capabilities. The package bundles Flask, flask-compress, and flask-restful as runtime dependencies and ships as a command-line tool.
The visualizer is designed for developers and engineers working with F Prime systems who need to inspect component relationships and system architecture in a graphical format. It runs locally as a Flask server and allows theme selection and canvas configuration through command-line arguments and direct file editing.
Use it for
- Visualize F Prime system component topologies during embedded systems development and debugging.
- Generate and capture PNG screenshots of flight software architecture diagrams for documentation.
- Inspect component connections and data flow in F Prime projects via an interactive browser interface.
- Customize visualization appearance by selecting or creating themes with RGBA color support.
