fprime-visual

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.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

A browser-based web application for visualizing F Prime flight software system topologies from JSON layout files.

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.

Install

fprime-visual on PyPI

pip install fprime-visual

uv add fprime-visual

poetry add fprime-visual

Installing fprime-visual

Before you install

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.

License in practice

Apache License 2.0 is permissive; you may use, modify, and distribute the package freely provided you include the license and document changes. No restrictions on commercial or private use.

Quickstart

pip install fprime-visual
fprime-visual --source-dir examples/

Requires F Prime Layout JSON files as input; the package reads topology data from .json files, not raw F Prime projects.

Verify before relying

• Whether the package works with F Prime versions released after 2023-12-15.
• Whether flask, flask-compress, and flask-restful versions have known incompatibilities with Python 3.12.
