- Rendered page inspection for titles, descriptions, canonicals, headings, links, images, structured data, social metadata, styles, accessibility signals, and source-vs-rendered differences.
- Robots.txt review with crawler comparisons for search crawlers, AI search bots, AI training crawlers, and user-retrieval bots.
- Editable desktop and mobile SERP previews with rich-result-style modules and PNG/WebP preview downloads where downloads are supported.
- Rendered accessibility tree review with landmarks, headings, controls, images, issue chips, copy output, and JSON export.
- Colorblind-friendlier accessible color palette for users who do not want severity communicated by red and green alone.
- CSV, TSV, JSON, Markdown, spreadsheet, image, schema, SERP image, and accessibility-tree exports where supported by the browser.
Known Browser Limits
- Toggle JavaScript is not available because Firefox does not expose Chromium contentSettings.javascript.
- Some context-menu placements depend on Firefox's supported extension contexts.
