Is Weaviate safe? Weaviate scores 75.0/100 (Grade B), ranked #92 of 1283 tracked open-source AI agent projects, on evidence coverage A (4 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 6.7/10; 50% of recent commits are signed; last pushed 2026-08-14. Every point is earned from checkable signals — never paid placement. How scoring works →

Activity sub-score · out of 100

In Memory & Knowledge

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. 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 Weaviate safe?

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

Does Weaviate publish package provenance?

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

Does Weaviate have an OpenSSF Scorecard?

Weaviate has an OpenSSF Scorecard score of 6.7/10. 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 Weaviate actively maintained?

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

What license does Weaviate use?

Weaviate ships under BSD-3-Clause. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Weaviate's commits signed?

50% of the last 100 commits to Weaviate 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 Weaviate?

For maintainers

HVTrust scores Weaviate 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.
