ComputedKit

Inspect what the browser is rendering

• Scan the current page for computed colors, typography, spacing, corner radii, and shadows.
• Pick a specific element to inspect a bounded selector, computed values, and nearby elements.
• Search, filter, highlight, copy, and export the results you choose.
• Review observable image, SVG, favicon, and background-image references without downloading their bytes during a scan.

Built around explicit actions

Nothing is scanned merely by opening the extension. ComputedKit receives temporary access to the active tab only after you invoke it, and scans begin only when you select Scan page or Pick element.

Page-derived results stay in the side panel on your device unless you choose to copy or export them. An asset is requested from its source website only after you click Download.

Useful boundaries, stated plainly

Computed values are observations of the current rendering, not claims about a site's original design tokens. Typography reports declared font stacks, and asset downloads are best-effort where the source website permits access. The interface shows scan limits and unavailable observations rather than silently treating them as complete.

Support and feedback

For beta feedback or support, open an issue in the ComputedKit issue tracker. Do not include page inspection results unless you choose to share them.
