Category pages are most useful when you compare similar kinds of projects rather than treating the top row as an automatic recommendation list. Look at star concentration, language mix, and recent activity together to decide whether a category is dominated by a few established leaders or by a broader set of active tools.
Repositories are curated under the "project-based-learning" topic tag and ranked by star count. We favor projects that include complete source code, detailed instructions, and cover real-world use cases.
