Tail Lens for Tailwind: Inspect, Edit, and Build Tailwind CSS Visually

About

Tail Lens is a developer-focused Chrome extension that works like devtools for Tailwind CSS. It is a Tailwind CSS inspector and visual class editor that helps you inspect Tailwind classes, debug Tailwind layouts, and speed up your frontend workflow.

Inspect any element, see all its Tailwind utility classes at a glance, try class alternatives with live preview, and copy the final Tailwind class list in one click.

No more digging through browser devtools, guessing which Tailwind CSS utility is affecting your layout, or constantly switching between editor and browser. Tail Lens turns Chrome into powerful Tailwind devtools so you can build, refactor, and debug Tailwind CSS faster.
