Hey everyone 
I’ve been building in Bubble for a while now and, like most of you, I’ve spent way too many hours doing responsive design the hard way — creating conditionals one by one, element by element, property by property.
So I built something to fix it. It’s called Reflow (reflow.website)— a Chrome extension that sits inside Bubble’s editor and changes how you work with responsive.
What it does
Responsive mode: You switch to a breakpoint (320px, 768px, whatever), edit your elements normally — font sizes, paddings, widths, visibility — and Reflow automatically captures every change and saves it as a proper Bubble conditional. No more manually creating conditions. Just edit and done.
It also lets you:
-
Copy responsive styles from one element to all its siblings in one click (huge for cards)
-
Undo everything in one click if something breaks
-
Track your session — see every element you edited and what changed
CSS Animations (new): This one I’m really excited about. You can now add CSS animations to any Bubble element — hover effects, entrance animations, loops, text effects — all without writing a single line of code. Reflow injects pure CSS, so there’s no performance hit and no plugins needed.
15+ animations built-in: Hover Lift, Scale Pop, Tilt 3D, Fade In Up, Shimmer, Blur Reveal, and more. Each one has its own controls (duration, delay, intensity) with live preview right in the editor.
AI mode (Pro): For when you don’t want to do it manually at all — Claude AI analyzes your entire page, takes real screenshots to verify the layout, and generates all the responsive conditionals automatically. You can apply or discard with one click.
I’ve been building this for a few months and I think it’s ready for other people to try. I’m looking for early access testers who:
-
Build in Bubble regularly
-
Deal with responsive design (so… everyone?)
-
Want to try it and give honest feedback
How to get early access
reflow.website — leave your email and I’ll send you the download link.
The responsive mode (manual) is free. AI mode and animations are part of Pro but early access testers get an free trial.
I’d really appreciate any feedback — what works, what doesn’t, what features you’d want to see. I’m building this for the Bubble community so your input directly shapes what comes next.
Happy to answer any questions here. Thanks for reading!
