Growth we measured
15 daily star snapshots stored by whatstrending.ai, 2026-09-22 to 2026-10-06. GitHub shows today's number; this is the movement behind it.
- Ranked #1580 by stars among the 2,497 repos we snapshot, using the latest star count we recorded for each.
- Its 7-day pace is faster than 74% of the 1,252 repos where we can currently measure one (#325).
How this is measured. whatstrending.ai stores its own daily star and fork snapshot for every repo in its trending index. Every figure above is a delta between two of those stored rows — 15 snapshots for undefined-ui/second-brain-os between 2026-09-22 and 2026-10-06. Our history starts 2026-06-19; we hold nothing from before that date. Nothing here is estimated, interpolated or back-filled, and days without a snapshot are simply not plotted.
Add the Trending AI Repo badge to your README
undefined-ui/second-brain-os is in the whatstrending.ai tracked index, so this badge already resolves. It is free, needs no account, and updates itself: the rank is recomputed from our stored daily snapshots and the image is re-fetched a few times a day. Clicking it lands on this page, which shows the star history we measured.
