In detail: Arize Phoenix scores 76.0/100 (Grade B), ranked #217 of 1371 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; no OSSF Scorecard result yet; 81% of recent commits are signed; no published advisory affects its latest release (arize-phoenix); last pushed 2026-10-09. Every point is earned from checkable signals — never paid placement. How scoring works →

How Arize Phoenix could raise its score

Each line changes one public signal and recomputes with the live scoring function. The gains don't add up exactly, because the score is capped near the top.

Chain of custody

Scanners check what the code says. This traces who ships Arize Phoenix and whether that has changed: from the source repository, through how changes are reviewed and released, to the package you install. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.

  1. Source Signed

    github.com/Arize-AI/phoenix, NOASSERTION, last pushed 2026-10-09. 81% of the last 100 commits carry a verified signature, so changes trace to a verified account.

  2. Review and release Not checked

    No OpenSSF Scorecard result yet, so branch protection, code review and release signing are unverified.

  3. Published packages Partly attested

    • npm phoenix-js No source link declared No build attestation
    • PyPI arize-phoenix Source link points back to this repo Build provenance attested
  4. What you install today No known advisories

    Latest release checked: arize-phoenix 20.19.0. No published advisory affects it (OSV, checked 2026-10-09).

Changes to this chain

No change to package provenance, package source links, Scorecard coverage or license in HVTracker's daily snapshots of Arize Phoenix.

Evidence behind this score

Coverage A: 4 of 5 independent evidence types found.

  • GitHub repository data
  • Package downloads
  • Supply-chain checks
  • Public actions (missing)
  • Community mentions

Verify this score yourself

Every build re-issues Arize Phoenix’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.

What this score doesn’t check

It covers who ships the code, not what the code does. It doesn’t read tool descriptions or prompts for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you connect it, such as Cisco MCP Scanner or Snyk Agent Scan.

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 →

Common questions about Arize Phoenix

Source-available software. A lower HVTrust score reflects fewer public supply-chain artifacts (open license, build provenance, signed commits) — not a security finding. Arize Phoenix may have internal security practices not visible through public signals.
Public supply-chain signals for Arize Phoenix are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but Arize Phoenix carries less obvious unverified-evidence risk than projects with thin signals.
Does Arize Phoenix publish package provenance?
Yes. Arize Phoenix's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does Arize Phoenix have an OpenSSF Scorecard?
No OpenSSF Scorecard data is currently published for Arize Phoenix. Maintainers can enable the Scorecard GitHub Action to get a public score; without it, automated supply-chain hygiene is harder for outsiders to verify.
Is Arize Phoenix actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Arize Phoenix use?
Arize Phoenix ships under NOASSERTION. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Arize Phoenix's commits signed?
81% of the last 100 commits to Arize Phoenix 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 Arize Phoenix?

For maintainers

HVTrust scores Arize Phoenix 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.
