How projects are selected

Projects are public GitHub repositories found with the GitHub search query “topic:flask” and at least 30 stars. Each repository is checked against Flask’s languages and ecosystem before it is categorized, and stars, forks and last-commit dates come straight from the GitHub API, refreshed daily (current snapshot: October 6, 2026). Nothing here is paid placement.
