How are the picks ranked?
Each list starts from the apps, MCP servers or skills that fit the question, then ranks them by GitHub stars and recent commit activity. Licence and Docker support are shown for every pick, and archived or abandoned projects are left out.
How often are the answers updated?
The GitHub data behind every answer is refreshed nightly, and the pages are rebuilt from that snapshot. Each page shows the date of the data it was built from.
Are any of the picks sponsored?
No. Placement on these pages cannot be bought. The order comes only from public GitHub data and the fit for the question.
