ScaleCUA
[ICLR 2026 Oral] ScaleCUA is the open-sourced computer use agents that can operate on cross-platform environments (Windows, macOS, Ubuntu, Android).
Is ScaleCUA safe? Thin or incomplete trust evidence. Review carefully before production use.
Compare ScaleCUA
How does it stack up against its Browser & Computer Use neighbours?
Pick any agent to compare →In detail: ScaleCUA scores 30.0/100 (Grade D), ranked #1336 of 1374 tracked open-source AI agent projects, on evidence coverage C (2 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 1.4/10; 61% of recent commits are signed; last pushed 2026-01-07. Every point is earned from checkable signals — never paid placement. How scoring works →
How ScaleCUA 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 ScaleCUA and whether that has changed: from the source repository, through how changes are reviewed and released, to the code you run. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.

Source Partly signed
github.com/OpenGVLab/ScaleCUA, Apache-2.0, last pushed 2026-01-07. 61% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

Published packages None
No registry package. ScaleCUA is used from its repository, so what you run is whatever you check out: pin a release tag or commit.

Verify this score yourself
Every build re-issues ScaleCUA’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 D reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Does ScaleCUA publish package provenance?
Does ScaleCUA have an OpenSSF Scorecard?
Is ScaleCUA actively maintained?
What license does ScaleCUA use?
Are ScaleCUA'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 ScaleCUA?
For maintainers
HVTrust scores ScaleCUA 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.
