SuperDev Pro

SuperDev Pro packs 30 web developer tools into one extension for designers & developers.

SuperDev Pro: Launched, open signup. Get it at superdevpro.com.

SuperDev Pro is a browser extension for web developers and designers that gathers more than 50 tools into a single install. Users can click any element to inspect and live-edit its CSS, grab colors with an eyedropper, preview and swap fonts, measure spacing with a page ruler, and preview layouts across several device sizes at once. It also extracts every image on a page, scrapes data to JSON, CSV or Excel, exports elements as HTML/CSS, and detects a site's tech stack. It runs locally without telemetry on Chrome, Firefox, Edge and other browsers. A free plan includes 11 tools; a one-time lifetime payment unlocks all of them.
