DevBoost

Fast front-end toolbox: color picker, palette scan, assets, responsive, capture & annotate, SEO, accessibility, debug. DevBoost is a compact, MV3-powered toolbox that speeds up everyday front-end work—right inside the page you’re viewing. Toggle it on, pop open a panel, and get actionable insight in seconds. Highlights Inspector – Lightweight on-page helper to surface DevBoost tools. Eyedropper – Pick any color on the page. Colors – Scan used/defined colors and highlight where they appear; export results. Fonts – Inspect families, weights, sizes, and loaded font files. Assets – List images/CSS/JS. Filter and open/download quickly. Responsive – Test common breakpoints or custom sizes fast. Site Stack – Best-effort detection of libraries and analytics. SEO – Check titles, metas, canonicals, robots, headings, links. Accessibility – Find heading order gaps, low contrast, missing labels; click to scroll & highlight the issue. Capture – Viewport/full-page/element/area screenshots with annotations. Tab recording (simple stop bar). Performance – Quick timing/resource insights; optional auto-open on hard reloads. Debug – Overlay for console/errors/network/memory plus GTM/Tealium DataLayer events. Quick tools & hotkeys – Clear cache for the current origin, jump to panels, and assign keyboard shortcuts. Why DevBoost? Fast & focused – Panels open instantly; highlights track while you scroll. On/off master switch – A single toggle disables all injection and hotkeys when you don’t need it. Privacy-minded – Processing happens locally in your browser. DevBoost doesn’t transmit your page data. (See the privacy policy for details.) Notes & permissions Requires standard permissions for features you use (e.g., tab capture, downloads). Chrome restricts extensions on some pages (e.g., Chrome Web Store, chrome://).
