This repository (OSGL) is a curated catalog of open‑source games, game engines, frameworks and tools. It ingests metadata from external APIs (GitHub, GitLab, SourceForge, LibreGameWiki) and transforms them into a collection of structured Markdown files (over 1800 entries). A static site generator (Python + Jinja2 + Bulma) produces a browsable website with alphabetical, genre, platform and inspiration indices. The project provides maintenance scripts (Qt UI, batch validation, screenshot management) and synchronisation modules for keeping the catalog up‑to‑date. It is primarily a data curation and publishing project rather than a runnable application, but its Python tooling demonstrates good engineering for a data pipeline.
