About the Data and Ranking
Public repositories returned by GitHub Search, including forks and archived repositories. Search indexing, candidate scope and pagination limit global completeness. Counts are exact API integers at retrieval, not live counters.
Query: stars:>1000 is:public fork:true. Two pages of 100 results, sorted by stars. All 200 records are validated before replacement; the previous snapshot survives a failed check. Categories are editorial, generated from documented topic and description rules.
Stars reflect interest and popularity, not software quality, safety, or maintenance guarantees. Purpose text comes from upstream repository metadata. README examples are source-extracted and are not execution tests.
Storage: D1. Last Check: 11 Nov 2026, 17:19 UTC. Next Target: 12 Nov 2026, 19:00 UTC. Schedule configuration is verified separately in the operator runbook.
