## Repos with it, by month

From commit dates in each repo's history. The last few days always look low, because repos found later fill them in.

| Month | Repos at month end |
|---|---|
| [2026-08](https://favz.co/months/#2026-08) | 6 |
| [2026-09](https://favz.co/months/#2026-09) | 16 |
| [2026-10](https://favz.co/months/#2026-10) | 22 |

Each linked month leads to what else people first added that month. All months: https://favz.co/months/index.md
