Description

Extracts color palettes, typography, tech stack, and SEO/meta data from any live website. Spectra inspects any website you visit and surfaces design and technical details in one clean popup. COLOR — Extracts the page's color palette from DOM styles and CSS variables. Copy hex values or download a palette file. FONTS — Detects font families, weights, and sizes used across the page. STACK — Identifies frameworks, CMS platforms, analytics tools, and server technologies from page signals and response headers. META — Surfaces SEO tags, Open Graph data, document title, and other head metadata. All scanning runs locally in your browser. No accounts, no cloud sync, no data collection. Open the popup on any page, browse the tabs, and hit RESCAN to refresh. Use DOWNLOAD to export your results.
