Maintainer Checklist

Raise Scorecard signals Current OSSF Scorecard is 1.3/10. Tighten the weakest checks to improve public safety evidence.

Publish provenance Add package provenance or release attestations so users can verify where shipped artifacts came from.

Increase signed commits Raise the share of verified-signed commits to make maintainer identity and release history easier to trust.

Refresh maintenance signals The repo was last pushed 92 days ago. Fresh activity helps separate stable projects from stale ones.

In Browser & Computer Use

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 B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

Is OpenCUA safe?

Public trust evidence for OpenCUA 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 OpenCUA publish package provenance?

No published build provenance is currently detected for OpenCUA. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.

Does OpenCUA have an OpenSSF Scorecard?

OpenCUA has an OpenSSF Scorecard score of 1.3/10. 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 OpenCUA actively maintained?

Slowing down. Last push was 92 days ago — keep an eye on whether activity resumes.

What license does OpenCUA use?

OpenCUA ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are OpenCUA's commits signed?

26% of the last 100 commits to OpenCUA 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.

Maintain OpenCUA?

For maintainers

HVTrust scores OpenCUA 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.
