How it works
- 1.Validates the public URL and rechecks the final browser redirect before analysis.
- 2.Captures desktop and mobile screenshots plus extracted above-fold text with Playwright and serverless Chromium.
- 3.Sends that evidence to Gemini 2.5 Flash through Vertex AI using a structured eight-dimension rubric.
- 4.Returns the structured critique directly without persisting screenshots, a critique record, or a shareable result.
- 5.Applies an in-memory five-per-IP daily limit and a configurable global daily cap; cold starts reset those counters.
