50 Top New Tools for Freelancers

50 free web tools

In many occupations, solving problems and finding ways to be more productive are top priorities. This is especially true for web designers and frontend developers who perform and repeat many micro-tasks. The fact we work with open web technologies that are often used to build free and open source software means we have a plethora of tools at our disposal.

In my ongoing research into web tools, I come across dozens of new options every week – scripts, plugins, WordPress themes, browser extensions, native apps, web services, libraries, frameworks, web templates, graphic packs and so much more.

After wading through the mountains of possibilities, I’ve put together a categorised list of 50 amazing web tools that can benefit web designers or frontend developers. And the best part? These web tools are all absolutely free!

HTML, CSS & Sass Tools

This is an open-source script that converts your Ilustrator documents to HTML and CSS, from the developers at the New York Times. It looks like a really powerful and useful tool for designers who work in Adobe Illustrator. The script is a JavaScript file that you download and drop into the scripts folder of your Illustrator install.

02. PostCSS

The community around PostCSS is gaining momentum and growing steadily. It’s a toolkit of JavaScript plugins that helps you take advantage of the latest standards and conveniences in CSS development, and it’s well worth looking into.

04. UIkit

50 free web tools - Uikit

UIkit’s a plucky young competitor in the frameworks hood

While Bootstrap and Foundation are the clear winners in terms of popularity in the framework space, UIkit is worth checking out. Its core features and interface components are right up there with the big kids on the block.

05. AniCollection

AniCollection is a library of CSS animations. It sports an interface that lets you easily add animations to your collection and quickly grab the necessary HTML, CSS or JavaScript code to implement them in your project. You can even submit your own.

08. HTMLHint

HTMLHint is a static code analysis tool for HTML

Linting has slowly overtaken validation in importance. This tool has multiple options and lets you cycle through the warnings and errors in your code.

DomFlags makes it easier to navigate deeply-nested HTML elements in the DevTools

18. VerbalExpressions

If you’re like me and can’t stand the thought of writing regular expressions from scratch, this is the library for you. It’s a plain-English way to write regex and since the return value compiles to the actual expression, it can be a great way to learn, too.

19. Skeuocard

Skeuocard progressively enhances credit card inputs with its skeuomorphic interface. There are a few scripts like this one, but Skeuocard is one of my favourites. Users enter their details inside a realistic representation of a credit card, which automatically matches the layout of the specific card type (Visa, Mastercard etc.). They can even flip the card over to fill in the other side.

This is not just another code style linter. What’s so powerful about JSCS is that it enables you to specify your own custom style guide, against which your code is linted. Alternatively, you can choose to test your codebase against popular style guides from jQuery, Airbnb, Douglas Crockford, Wikimedia and more.
