Reviewer notes

Source Reviewed review. These are observations, not a security certification.

Official Google ChromeDevTools org package. 2.55M monthly downloads, Apache 2.0 license. Zero runtime npm dependencies (all bundled) — excellent for security. Maintained by Google engineers. Pre-1.0 (API instability). Requires Chrome running with remote debugging port open.

Remote debugging access to Chrome: can read page content, network traffic, cookies, and DOM — full browser session visibility. Appropriate for local development but dangerous in shared/cloud environments. Zero runtime dependencies is strong supply chain posture. Requires explicit Chrome debugging port configuration.

2026-04-02: LIMITATION: Requires Chrome running with remote debugging port open — that port grants full browser session visibility (cookies, network, DOM). Dangerous in shared or cloud environments.
