How it got here
2017–2021 · Flame 1.37.0 release and ecosystem expansion
This period centered on the release of Flame 1.37.0, which introduced a comprehensive new effects system, a modernized game architecture, and a complete overhaul of the 2D rendering pipeline. The team significantly expanded the library's capabilities by adding new components for input handling, particle systems, and UI widgets, while simultaneously integrating bridge packages for physics, SVG, and state management. This was accompanied by a major documentation update using Sphinx and the creation of a unified example app to showcase the new features.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 5 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 2061a4ffb7 — the exact code this score is about.
- Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
