Changelog

May 2026 — v2.2

New

accessibility_audit tool — Real WCAG 2.1 AA compliance checks: landmarks, skip links, focus indicators, heading hierarchy, image alt text, SVG aria-hidden, color contrast ratios (computed from RGB with WCAG math), form labels, language attribute, and reduced-motion handling. Returns categorized PASS/FAIL/WARN results with WCAG criteria references.
extract_text_from_image (OCR) tool — AI-powered text extraction from screenshots, photos, infographics, and any image with embedded text. Works standalone with a URL or within a browser session. Powered by Kimi k2.5 vision.
seo_batch_compare tool — Compare SEO metadata across 2–10 URLs in one call. Returns a comparison table showing duplicated titles, descriptions, OG tags, and canonical issues across pages.
OCR CLI command — npx deepsyte ocr <url> extracts text from any image via the command line (CLI v1.20.1).
responsive_audit tool — One-call responsive design audit within a browser session. Detects horizontal overflow with culprit elements (tag, class, bounding rect), checks touch targets (≥44×44px), finds text below 16px, verifies viewport meta tag, checks input font sizes for iOS zoom prevention, and reports tightly-spaced interactive elements. Returns a structured pass/fail report.

Improved

find_breakpoints enriched — Now returns a structured width table with overflow status (✅/❌), height, and scrollWidth at each of 23 viewport widths (320–1920px). Also reports which widths start/stop overflowing and extracts CSS @media breakpoints.
browser_seo_audit semantic validation — Now detects canonical/og:url mismatches, robots.txt sitemap cross-domain issues, Disallow: / blocking, and cross-page duplicate titles/descriptions/OG tags within the same browser session.
og_preview enhanced — Social card previews now include semantic validation warnings for OG tag mismatches.
browser_perf_metrics LCP fix — LCP now uses a PerformanceObserver with 5s timeout instead of a synchronous check. No more "N/A" on pages with lazy-loaded LCP elements.
ux_review grounded in DOM data — The AI reviewer now receives verified "ground truth" (landmarks, SVG counts, structured data, perf metrics) so it cannot contradict measured facts. Eliminates false positives like "no alt text" on pages with zero images.
accessibility_snapshot renamed — Description now accurately reflects it as a raw tree viewer and points to accessibility_audit for compliance checks.
Browser tool timeouts — Improved timeout handling and file:// URL detection with clear error messages.

New

Outbound webhooks — subscribe HTTPS endpoints to screenshot.completed, screenshot.failed, run.completed, run.failed, quota.warning, and test.ping. HMAC-SHA256 signed deliveries with Webhook-Id / Webhook-Timestamp / Webhook-Signature headers, retried 6× over ~14h (1m / 5m / 30m / 2h / 12h). Manage from /dashboard/webhooks, REST /v1/webhooks, MCP (webhook_* tools), or CLI (deepsyte webhooks:*).
Visual diff REST endpoint — POST /v1/screenshot/diff returns beforeUrl, afterUrl, diffUrl, and pixel-change percentage in a single sync call.
GitHub Action for visual regression — stevejford/action@v1 posts a sticky PR comment with baseline / preview / diff images and fails the check above your configured threshold.
Quota warnings — quota.warning fires once at 80% and once at 95% of your monthly cap so you can self-throttle before hitting 429.
