In Coding Agents

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade C reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Does Vercel fx publish package provenance?

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

Does Vercel fx have an OpenSSF Scorecard?

Vercel fx has an OpenSSF Scorecard score of 2.3/10. 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 Vercel fx actively maintained?

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

What license does Vercel fx use?

Vercel fx ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Vercel fx's commits signed?

100% of the last 100 commits to Vercel fx 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.
