140 of your 164 findings came from Repobility's proprietary detections. ✓ Repobility tags below mark them.
Upstream (GitHub) caused delay on this scan — not Repobility.
  • GitHub API rate-limited (HTTP 403) — preflight skipped, fell back to direct git clone.
  • Clone from GitHub took 158.22s for a 492.6 MB repo slow.
  • Repobility's analysis ran in 7.74s after the clone landed.
