Frequently Asked Questions
All-in-one extensions reduce browser clutter, provide a consistent interface, and often work better together. Instead of 6 extensions from 6 developers with 6 different UIs, you get one cohesive toolkit. It also reduces potential conflicts between extensions.
Frontend Hero is the only all-in-one extension with dedicated Tailwind support. It includes a Tailwind Scanner (view classes by category), Tailwind Converter (CSS to Tailwind), and a color picker that outputs Tailwind class names.
Yes, VisBug is completely free and open source. It was created by Adam Argyle, who works on the Chrome DevTools team at Google. There are no premium features or subscriptions.
You can, but it's not recommended. They may conflict or add unnecessary overhead. Pick the one that best matches your workflow. If you need Frontend Hero's Tailwind features but also VisBug's manipulation tools, using both is fine - they don't overlap much.
