As a tech lead (or whoever makes the technical decision), it looks very tempting to adopt the open source UI libraries, if possible. In the React.js land, I used a bit of Charkra UI and Reakit. Source: almost 2 years ago

I'm currently considering React-aria, HeadlessUI, Radix-ui and Reakit for reimplementing the user-interface for a customer, but I find it hard to choose. Source: about 2 years ago

I’ve got some libraries I’m looking into to fill the gap. Currently looking at radix, reakit, and react-spectrum. Source: over 2 years ago

Regardless of what you use for styling though, you should look into so-called headless ui components. These are hooks and components only focused on functionality and accessibility, which you then use to build your own styled components. Some examples are https://reakit.io/, https://www.downshift-js.com/ and https://headlessui.dev/. Source: about 3 years ago

For common components, I can't recommend Reakit enough. It's a keyboard accessible, unstyled component library with dialogs, popovers, and much more. I use it for all of my personal projects nowadays. Combined with Framer Motion for animation and Styled Components for styling, it's a killer mix. - Source: dev.to / about 3 years ago

I know that Xcode does a decent job debugging views but there is some times it simply is unable to capture the view. Also I'd like to be able to edit constrains and so like Reveal does. I'd buy Reveal since it is a great app but its price is absurd AND it is an annual subscription so... Source: 7 months ago

I like to use Reveal to help me find accessibility issues. It’s good for finding colour blindness and contrast issues too. Source: almost 2 years ago

Https://revealapp.com was the earliest and still has the most features as far as I know. Great app if you’re working on iOS apps. Source: about 2 years ago

That gives you a similar view, but I’m pretty sure this isn’t that. Nor does it look like Reveal. I’m really curious what it is as well. Source: about 3 years ago
