Maintainer Checklist
Raise Scorecard signalsCurrent OSSF Scorecard is 2.7/10. Tighten the weakest checks to improve public safety evidence.
Publish provenanceAdd package provenance or release attestations so users can verify where shipped artifacts came from.
Increase signed commitsRaise the share of verified-signed commits to make maintainer identity and release history easier to trust.
Refresh maintenance signalsThe repo was last pushed 165 days ago. Fresh activity helps separate stable projects from stale ones.
How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade D reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage A is separate — it grades how many independent signal types back the score (4 of 5), so a high score on thin evidence stays visible. Full methodology →

Is UI-TARS safe?
Public trust evidence for UI-TARS is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.
Does UI-TARS publish package provenance?
No published build provenance is currently detected for UI-TARS. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does UI-TARS have an OpenSSF Scorecard?
UI-TARS has an OpenSSF Scorecard score of 2.7/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.
Is UI-TARS actively maintained?
Slowing down. Last push was 165 days ago — keep an eye on whether activity resumes.
What license does UI-TARS use?
UI-TARS ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are UI-TARS's commits signed?
19% of the last 100 commits to UI-TARS are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.
Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.
These runtime-trust fields — detected from public repo docs and manifests — contribute a bounded adjustment to this project's HVTrust score alongside supply-chain evidence.

Maintain UI-TARS?
HVTrust scores UI-TARS from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
