Every component [from Components UI] was fully ready to use but also highly customizable. I also purchased Build UI to add in some additional functionality and I am 100% pleased with the result.

What's this

“I want to build a website to sell my products and services but…
...I don’t know how or where to start”

Hi! I’m Oscar O. Arévalo. I’m an industrial engineer and I like to build projects online. I’ve been using to build side hustles, to sell products and for other projects but found myself wanting to add complex components - like a navbar or a dynamic feature section - to a new Carrd project.

One starry night I decided to start Build UI: a compilation of step-by-step tutorials, videos and code snippets to guide you on how to make these complex components into your new or existing Carrd projects.

Build UI is meant to be used as a reference tool: Decide what component(s) you want to build in your project, follow the steps in the tutorial and copy the code (if necessary) to build it. That’s it.

"But I’m not a developer nor a designer"

I started Build UI with this in mind. You don’t need to know how to code or to be a web designer. It allows you to do just one thing: build complex and beautiful components without knowing any code and without paying a developer for it. Use it for you digital products, services, businesses and more.

Use Build UI whether you're a Carrd beginner or an expert. You can start from scratch and follow the tutorials to begin with a blank canvas. Then just add as many components on your website as you see fit. That easy.

What's included

Step-by-step video and written tutorials with detailed illustrations

The eBook in PDF

The eBook is like the Master index. Here you’ll find a list of all the components available and the tutorial for each one

Tutorial Videos

When there’s a video available for the components’ tutorial you’ll find it referenced on the eBook so you can look it up on your Gumroad downloads

Code Snippets

Pieces of code that you can copy and paste in your Carrd project using the Embed element

This is the complete list of components you'll be able to build. More components added regularly as free updates
