Activity sub-score · out of 100

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 A 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 Stagehand safe?

Public supply-chain signals for Stagehand are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but Stagehand carries less obvious unverified-evidence risk than projects with thin signals.

Does Stagehand publish package provenance?

Yes. Stagehand's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.

Does Stagehand have an OpenSSF Scorecard?

Stagehand has an OpenSSF Scorecard score of 5.2/10. 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 Stagehand actively maintained?

Actively maintained. The repository was pushed to within the last 1 day(s).

What license does Stagehand use?

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

Are Stagehand's commits signed?

100% of the last 100 commits to Stagehand 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.
