Unlike browser DevTools, Screen Ruler is built for design workflows: visual flexbox/grid breakdown, gradient inspection with color stops, multi-element pseudo-state simulation, CSS-to-Tailwind conversion, and a Page tab with Performance, SEO, and Social previews.
# Product Hunt Launch
Hi Product Hunt,
Over the last 6 months, Screen Ruler has continued to grow to over 50,000 weekly active users on the Chrome Web Store. Screen Ruler continues to evolve as I expand its feature set so this launch doesn't have a typical "theme". Just a whole bunch of cool new stuff to try!
- Stylesheet parsing: When selecting an element, see rules across all stylesheets that affect that element with specificity visualized.
- Page inspection: A new Page tab with Performance, SEO issues, and Social previews.
- Layout inspection block: A glanceable visual breakdown of flexbox and grid: axes, justify/align, gap, and tracks.
- Inspector pinning: Now you can pin the floating inspector.
- State simulation: Force an element into a different pseudo-state (hover, focus, active).
- CSS to Tailwind conversion: Convert any element's CSS to Tailwind utility classes.
- Breakpoints, box-model margin indicators, HSB color space, element-probe contrast detection, plus dozens of refinements across the inspector flow.
Product Hunt Exclusive: Get 15% off Pro with code PH15OFF at checkout. Valid until the end of the month.
