Is CopilotKit safe? Strong public trust posture, backed by multiple independent signals.
Compare CopilotKit
How does it stack up against its UI & App Builders neighbours?
Pick any agent to compare →In detail: CopilotKit scores 80.8/100 (Grade A), ranked #142 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; 57% of recent commits are signed; no published advisory affects its latest release (@copilotkit/react-core); last pushed 2026-10-09. Every point is earned from checkable signals — never paid placement. How scoring works →
How CopilotKit 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 CopilotKit 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.
-
Source Partly signed
github.com/CopilotKit/CopilotKit, MIT, last pushed 2026-10-09. 57% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.
-
Review and release Not checked
No OpenSSF Scorecard result yet, so branch protection, code review and release signing are unverified.
-
Published packages Linked and attested
- npm @copilotkit/react-core Source link points back to this repo Build provenance attested
-
What you install today No known advisories
Latest release checked: @copilotkit/react-core 1.77.1. No published advisory affects it (OSV, checked 2026-10-09).

Verify this score yourself
Every build re-issues CopilotKit’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.

Quick Trust Read
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 →

Does CopilotKit publish package provenance?

Is CopilotKit actively maintained?
What license does CopilotKit use?
Are CopilotKit's commits signed?
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 CopilotKit?
For maintainers
HVTrust scores CopilotKit 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.
