Is Guardrails AI safe? Guardrails AI scores 81.8/100 (Grade A), ranked #61 of 1204 tracked open-source AI agent projects, on evidence coverage A (4 of 5 independent signal types). The public evidence: its packages ship with cryptographic provenance; OSSF Scorecard rates its supply-chain practices 6.0/10; 100% of recent commits are signed; last pushed 2026-08-05. Every point is earned from checkable signals — never paid placement. How scoring works →

In Security & Guardrails

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 Guardrails AI safe?

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

Does Guardrails AI publish package provenance?

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

Does Guardrails AI have an OpenSSF Scorecard?

Guardrails AI has an OpenSSF Scorecard score of 6.0/10. 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 Guardrails AI actively maintained?

Actively maintained. The repository was pushed to within the last 4 day(s).

What license does Guardrails AI use?

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

Are Guardrails AI's commits signed?

100% of the last 100 commits to Guardrails AI 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.
