- Buy it already. I have used UI Inspector for over 3 years and it is still the first tool I reach for every time. UI Inspector quickly became the first tool I reach for in my workflow. It is easily my number 1 plugin and one of those rare extensions that you install once and immediately wonder how you ever worked without it. It should be a legal requirement for any designer who needs seamless access to these features to own UI Inspector. What really makes this product stand out is not only the quality of the tool itself but the person behind it. The creator is responsive, appreciative, and clearly invested in growing the product and supporting the people who use it. That mindset shows throughout the experience. Great tools usually come from people who deeply understand the problems they are solving, and this one clearly does. The moment you start using it, you notice how thoughtfully everything is put together. Something as simple as grabbing a brand color with the eye dropper or clicking to see a responsive grid break down a layout instantly makes understanding a design feel effortless. Being able to quickly identify fonts, colors, spacing, and structure without digging through layers saves an incredible amount of time and keeps your focus where it should be. It also goes far beyond simple inspection. You can adjust typography, experiment with spacing and layout, tweak colors or gradients, and see everything update live right on the page. When it is time to move fast, the ability to view and copy the generated CSS or export styles makes collaboration with a team smooth and practical. It genuinely feels like having a live design workspace built directly into your browser. You can tell this was built by someone who truly understands UX, UI, and how designers actually work day to day. That understanding shows in the details and in the overall experience. This extension deserves far more recognition than it gets. I recommend it constantly, and for anyone working in design or front end development, it quickly becomes an essential tool. Thank you for building something this thoughtful and well crafted. I am genuinely excited to see what comes next.

- The paid features ruin it given there is simply no reason for it to exist given the fact that what they are charging for doesnt cost them any money and is provided by other services for free on the same webstore along with the fact that even without extensions having any sort of normal browser you can go into the client side web code and do it yourself. I would respect if you made donations a way to fund development but paywalling things that cost you no money and that are available for free on other extensions is simply ridiculous. Sincerely software dev
