- +Inspects both Tailwind and non-Tailwind sites with a single tool
- +One-time $59 price includes all 11 tools

Verdict: Frontend Hero delivers the most complete Tailwind browser extension experience. Its Scanner and Converter together cover the full inspect-and-convert workflow, and having 9 additional tools in the same extension makes it the clear winner for Tailwind developers.
#2TailscanBest Scanner UX
Dedicated Tailwind CSS inspector and debugger with class search, live editing, and autocomplete. Focused exclusively on Tailwind-built websites.
Strengths
- +Excellent class search with fuzzy matching
- +Live class editing with Tailwind autocomplete
- +Clean, focused UI designed specifically for Tailwind
- +Responsive breakpoint visualization
Weaknesses
- -$149/year subscription required
- -Only works on Tailwind-built websites
- -No CSS-to-Tailwind conversion feature
- -No color picker, font detection, or screenshot tools
Verdict: Tailscan has the best scanner UX of any dedicated Tailwind inspector. Its class search and autocomplete are top-notch. However, the $149/year subscription and lack of conversion tools limit its overall value proposition.
#3Windy
CSS-to-Tailwind converter extension. Click any element to convert its computed styles into Tailwind utility classes.
Strengths
- +One-click CSS-to-Tailwind conversion
- +Affordable one-time pricing
- +Simple, straightforward interface
Weaknesses
- -No Tailwind class scanner or inspector
- -Conversion accuracy drops on complex layouts
- -Limited CSS property coverage
- -No Tailwind v4 support yet
Verdict: Windy is a decent single-purpose converter at an affordable price. It handles basic CSS-to-Tailwind conversion but lacks the scanner and inspector capabilities that professional Tailwind developers need.
#4DevTools for Tailwind
Chrome extension that adds Tailwind CSS awareness to Chrome DevTools. Detects Tailwind classes and suggests alternatives when inspecting elements.
Strengths
- +Integrates directly into Chrome DevTools panel
- +Free to use with no limitations
- +Lightweight — minimal impact on browser performance
- +Shows Tailwind class suggestions alongside CSS
Weaknesses
- -Only works inside DevTools, not as a page overlay
- -Limited class detection compared to dedicated scanners
- -Basic conversion that misses many properties
- -Development pace has slowed significantly
Verdict: DevTools for Tailwind is a useful free supplement that adds basic Tailwind awareness to Chrome DevTools. It's not a replacement for a dedicated Tailwind extension, but it's a nice addition for developers who live in DevTools.
#5Gimli Tailwind
Browser extension for quick CSS-to-Tailwind conversion. Click an element to see its styles converted to approximate Tailwind classes.
Strengths
- +Quick click-to-convert interface
- +Free version available for basic use
- +Shows both CSS and Tailwind output side by side
Weaknesses
- -Inconsistent conversion accuracy across sites
- -Many CSS properties produce no Tailwind output
- -No class scanning or live editing features
- -Limited development activity and updates
Verdict: Gimli Tailwind provides basic CSS-to-Tailwind conversion but falls short on accuracy and feature completeness. It's a starting point for quick lookups but not reliable enough for professional workflows.

Frequently Asked Questions
Frontend Hero ranked #1 with a 9.3/10 overall score. It combines a Tailwind Scanner (for inspecting classes), Tailwind Converter (for CSS-to-Tailwind conversion), and 9 more tools in a single $59 one-time extension. Tailscan came in second at 8.2/10 but requires a $149/year subscription.
A Tailwind scanner detects and displays existing Tailwind classes on page elements — useful for inspecting Tailwind-built sites. A Tailwind converter takes regular CSS and converts it into Tailwind utility classes — useful for migrating from CSS to Tailwind or extracting styles from non-Tailwind sites. Frontend Hero includes both.
Tailscan scored 8.2/10 and has the best scanner UX in our testing. However, it only works on Tailwind sites, has no converter, and costs $149/year ($447 over 3 years). Frontend Hero (9.3/10) offers both scanner and converter plus 9 more tools for a one-time $59 — making it the better value for most developers.
It depends on the tool. Tailscan only works on Tailwind-built websites. Frontend Hero works on any website — its Tailwind Scanner detects classes on Tailwind sites, and its CSS Scanner and Tailwind Converter let you extract and convert styles from non-Tailwind sites.
DevTools for Tailwind (6.2/10) and Gimli Tailwind's free tier (5.5/10) are the best free options. They provide basic class detection and conversion, but lack the accuracy and depth of paid tools. For professional Tailwind development, Frontend Hero ($59 one-time) offers significantly more value.
