Woman excited about building WordPress themes with Bootstrap and Flexy

The most popular web tools, combined

The web runs on WordPress (36% of all websites), Bootstrap (27% of all websites), and Advanced Custom Fields (over 1,000,000 active installs). Flexy combines all three into an easy-to-use theme framework.

Google loves Flexy, and so will you

Google uses Web Dev scores to adjust your rankings: most WordPress sites fail miserably (test yours). Flexy makes it easy to score 90+ for Speed and straight hundos for Accessibility, Best Practices, and SEO.

Logically structured for easy maintenance

Flexy themes are organized around blocks and utility classes, so your code base will be as clean and DRY as a Shenzhen chip fab. Navigate, update, and edit your code base with ease.

Fully documented for seamless hand-offs

Any front-end developer with a basic understanding of WordPress, Bootstrap, and Advanced Custom Fields can easily take over a Flexy project. Rest easy knowing your team will always be up to speed.
