Design Once, Build Everywhere: The Lego Principle for Page Builders

Page builders are powerful—but right now, they’re walled gardens. Every tool has its own way of doing things, its own patterns, and its own limitations. What if instead, we built with portability in mind?

In this talk, Tammie Lister introduces The Lego Principle: a call for a shared foundation across page builders where patterns, components, and styles can be created once, and used anywhere—without the headaches of reformatting, re-styling, or re-learning.

She’ll explore how builders can support seamless import/export, reduce duplication, and let users learn once and create everywhere. Crucially, this isn’t about making every builder the same—it’s about giving them a common language, while still leaving room for unique features, design choices, and creative flair.

It’s not about having more pieces—it’s about building smarter, together.
