Here’s how we’re different...

Support that actually helps.

1:1 sessions and forever-access to our online Slack community of creative students from around the world, learning to code together. With our team based worldwide, we can support you whether you're coding early in the morning or late at night.

You’ll make 4 real websites in 4 weeks.

Our course is practical, unlike other programs that take a month or more before you make your first website. We care about design and focus on creative industries — you're not learning computer science, you're learning to make websites you'd want to make.

Structured, yet flexible.

Our course is set-up to deliver 4 real projects – no bullshit – and we designed it so it’s totally flexible. While you can learn at your own pace, we’ll be here to guide you each week.

Design focused.

You don't need to be creative to take our courses, but everything we do is focused on making beautiful sites you actually want to make. This isn't your average online school — we focus on the practical aspect of learning.

Who is the course for?

Anyone who already has some front-end experience and is looking to level up on Javascript and CSS knowledge. This would be a definite next step if you’re keen to build impressive functionality and tackle more complex code problems.

Most of our students work in the creative industries – designers, strategists and copywriters are the most common jobs amongst our students – but you can work in any industry to join the course.

What do I need?

A computer (Windows, Mac or Linux) with the latest version of Chrome installed and a broadband internet connection. That’s it!

What to expect

In reassuringly linear chronological order, here’s what will happen after you sign up.

Before the course
During the course
After the course

Every Sunday evening or Monday night (depending on your timezone!), you'll get access to the next week's projects, which include video tutorials, homework and questions to test yourself against.

There will be around 3-4 hours of lessons a week – split into 5–30 minute long videos. It's up to your schedule when you do the videos – there's no live streaming as we cater for a worldwide audience.
