Is Haystack safe? Haystack scores 96.9/100 (Grade A), ranked #1 of 1283 tracked open-source AI agent projects, on evidence coverage B (3 of 5 independent signal types). The public evidence: its packages ship with cryptographic provenance; OSSF Scorecard rates its supply-chain practices 9.4/10; 100% of recent commits are signed; last pushed 2026-08-11. Every point is earned from checkable signals — never paid placement. How scoring works →

What Would Improve It

Improve adoption to lift the weakest part of the trust profile.

Maintainer Checklist

Keep signals current Trust posture is already in a healthy range. The main job is to keep provenance, maintenance, and public evidence fresh.

In Agent Frameworks

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 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 Haystack safe?

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

Does Haystack publish package provenance?

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

Does Haystack have an OpenSSF Scorecard?

Haystack has an OpenSSF Scorecard score of 9.4/10. 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 Haystack actively maintained?

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

What license does Haystack use?

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

Are Haystack's commits signed?

100% of the last 100 commits to Haystack 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 Haystack?

For maintainers

HVTrust scores Haystack 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.
