How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade B reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Full methodology →

Is LangChain safe?
Public supply-chain signals for LangChain are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but LangChain carries less obvious unverified-evidence risk than projects with thin signals.
Does LangChain publish package provenance?
No published build provenance is currently detected for LangChain. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does LangChain have an OpenSSF Scorecard?
LangChain has an OpenSSF Scorecard score of 6.4/10. 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 LangChain actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does LangChain use?
LangChain ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are LangChain's commits signed?
100% of the last 100 commits to LangChain 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.
Runtime trust — coming soon
HVTrust currently scores supply-chain signals. We're adding runtime trust next: what an agent actually does when it runs — what it can reach, which tools it carries, what external services it depends on. Track progress on the roadmap →

Maintain LangChain?
HVTrust scores LangChain 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.
