UI Radar v0.1.0-rc.2

UI Radar is a local-first CLI for finding visual inconsistencies in rendered web interfaces and turning them into explainable offline reports.

Highlights

• Detects spacing, near-duplicate color, typography, corner-radius, and alignment drift.
• Forms conservative peer groups before evaluating visual expectations.
• Generates a self-contained report with screenshot overlays, filters, search, keyboard navigation, and evidence for every finding.
• Uses a fresh Chromium context, sends no telemetry, and disables networking inside generated reports.

Verified release gates

• 94 automated tests and 3 browser end-to-end tests.
• 13 of 15 independently labeled messy-page inconsistencies detected.
• 0 medium/high findings on the clean fixture.
• 1,001-element performance fixture completes in about 1.45 seconds on the recorded development machine.
• Linux quality, Node.js 22, browser E2E, and macOS smoke jobs pass on GitHub Actions.

Changes since rc.1

• Increased only the CI time budget for the intentionally heavy 5,000-element failure-mode test.
• Runtime scan timeouts and the 5,000-element product safety cap are unchanged.
• Updated release metadata and packaging assertions to rc.2.

This is a GitHub source release candidate. The npm package has not been published yet.
