DOMgeist

About

DOMgeist is a local-first Chrome extension for page quality audits.

It scans the current tab after you click the extension action and reports accessibility, SEO, performance, storage, security headers, technology signals, scan history, and export controls.

It is built for developers who want a fast browser-side audit without sending page data to a server.

Features:
- Accessibility checks for headings, image alt text, forms, links, focus issues, ARIA references, contrast candidates, and SVG names
- SEO checks for title, meta description, canonical links, robots intent, Open Graph, Twitter Card metadata, and same-page anchors
- Performance signals for LCP, CLS, resource weight, long tasks, image dimensions, lazy loading, and DOM pressure
- Security header and cookie flag inspection when optional permissions are granted
- Storage summary for cookies, local storage, session storage, IndexedDB, and CacheStorage
- Local scan history with optional encryption
- JSON and CSV export
- Optional local Ollama suggestions from minimized scan summaries

No telemetry. No user accounts. No remote audit API. No cloud AI. Scan data stays in the browser unless you export it.
