The best UI design tools will save you a lot of time and effort. Whether you're creating a basic wireframe or a fully functional prototype, these tools will help you do so faster and more efficiently, by removing the need to reinvent the wheel, time after time.

The question, though, of which are the best UI design tools to use is a controversial one. A decade ago, Sketch ruled the roost, but since then a flurry of capable new contenders have made it difficult to know where to turn. To make things clearer, we've slimmed down the field in this article to the absolute best UI design tools available today. 

Meanwhile if you're looking for more general tools, see our guide to web design tools. Or you're a non-coder and just want to get a site up and running in the easiest way possible, check out our roundups of the best website builders and top web hosting services.

After its launch in 2010, Sketch quickly became the go-to UI design app amongst the professional globally. And although many rivals have chipped away at its market share since, its dominance as the industry standard has remained solid to this day. 

Sketch enables you to create hi-fi interfaces and prototypes, and instantly preview them on mobile devices. One of the great features is Symbols, where you can design UI assets and elements for reuse. This helps create design systems and keep your interfaces consistent. From there, you can easily export your design into a clickable prototype.

Note that Sketch is Mac only, and there's no free version, although there is a free trial. Sketch was previously available to buy for a one-off fee, but has now switched to a subscription model, starting at $9.99 a month.

Learning curve

Launched in 2016, Adobe XD has rapidly become popular throughout the design profession, and now rivals Sketch as the industry standard for digital prototyping. While each app has much to recommend it over the other, XD's big attraction over Sketch is that it works on Windows as well as Mac. 

If you're a keen Adobe user and new to XD, you may not find the interface very Adobe-like to begin with – it is a jump if you've been designing in Photoshop for a while. But it does stack up to the other leading tools out there, and is worth it if you are a big Adobe fan.

XD is part of the Adobe Creative Cloud collection of design tools, but there's also a limited free version, or you can subscribe to the full version as a single app. For more details, read our article on how to download Adobe XD
