How this list is made
- Every project Hysen Labs tracks is snapshotted once a day. A project's gain is its Star count at the end of the window minus the count at the start.
- Archived, mirrored and unlisted repositories are left out, and so is any project missing a snapshot near either end of the window; nothing is estimated.
- The arrow compares each place with the same window ending a day earlier.
