How listings work
Real projects only
Each project must have a public repository we can verify through the GitHub API. Anything we cannot verify is left out.
Honest licenses
We show the license GitHub detects. When a project uses a mixed or "fair-code" license, we say so instead of calling it open source.
Activity checks
Stats are refreshed regularly. Projects with no code push or release in 180+ days are flagged.
Get new open-source swaps by email
One short email a week: newly listed projects, big releases, and projects that went quiet. No spam.
