118 of your 201 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 46.76s for a 203.6 MB repo slow.
  • Repobility's analysis ran in 157.85s after the clone landed.
