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 filtered by the "security" topic and ranked by stars. We apply additional content filtering to exclude offensive security tools, focusing on defensive and educational projects that comply with advertising policies.
