If you’ve built on Bubble.io long enough, you already know how important user experience (UX) is, especially during those few seconds when your app is fetching data, saving entries, or performing background processes. Those in-between moments can either feel smooth and professional or clunky and unfinished. That’s where the CSS Loaders plugin by LessCode.io steps in. Built specifically for Bubble.io, this plugin delivers over 600 animated spinners sourced from the renowned CSS-Loaders.com, helping you turn otherwise dull loading states into eye-catching transitions.
What Does the Plugin Do?
At its core, the CSS Loaders plugin brings animated, CSS-powered loading indicators to your Bubble.io application. These aren’t just a few generic spinners. You’re getting access to a massive library of 600+ loading animations, ranging from sleek minimalist designs to quirky and fun loaders that add character to your app.
And the best part? You don’t need to write a single line of code. Just copy the animation snippet from css-loaders.com, paste it into the plugin interface, set your desired color, and you’re ready to roll.
Who’s This Plugin For?
This plugin was made for Bubble developers, designers, and founders who want to improve user interaction without getting bogged down in custom animation logic or external libraries.
It’s ideal for:
- Bubble.io creators working on MVPs who want their apps to feel more refined.
- Developers managing apps with high API usage or background workflows.
- Freelancers and agencies who build polished apps for clients.
- Anyone who wants better UX during loading states, but doesn’t want to deal with Lottie files or JavaScript-heavy animation libraries.
Key Features That Set It Apart
The CSS Loaders plugin by LessCode.io isn’t just a quick fix. It’s a serious UX enhancer. Here’s what you get:
Massive Animation Library: With 600+ options, there’s a loader for every type of interface, mood, and industry. From dots and bars to shapes, rings, and more, no two apps need to look alike.
Color Customization: Stay on-brand by setting the exact color of each loader. Whether your app’s theme is bold and vibrant or clean and neutral, your loaders will blend right in.
Zero-Code Setup: You don’t need to be a CSS wizard. Just grab the code, paste it into the plugin, and it works. Simple.
Lightweight & Fast: Unlike GIFs or heavy animation files, CSS loaders are snappy and don’t weigh down your app’s performance.
Improved User Retention: A smooth loading animation gives users visual feedback. It keeps them engaged instead of wondering whether your app has frozen.
The Problem It Solves
Let’s be honest…
Bubble apps aren’t always lightning-fast, especially if you’re pulling large datasets or using complex API calls. Without proper loading states, users are left staring at a blank screen. That’s not just frustrating, it’s damaging to trust and conversions.
This plugin solves a critical problem, as it fills the silence. It tells your users, ‘Hey, we’re working on it,’ and does so in a stylish, customizable way.
When This Plugin Saved the Day
A Bubble-based SaaS product was preparing for its beta launch. The app featured a dashboard with multiple repeating groups that fetched user-specific metrics through an external API. During internal testing, the founders noticed a pattern that users assumed the app had frozen and would refresh the page mid-load.
That’s when they installed the CSS Loaders plugin from LessCode.io.
In under 15 minutes, they had implemented distinct, branded loaders for each module. These loaders gave users visual feedback while the API fetched the data. The change was immediate. Bounce rates dropped. Feedback forms showed fewer complaints about slow loading. And during the public launch, users actually complimented the design details, especially the playful but clean loading animations.

Give it a try. Choose your favorite animation, paste the CSS, pick a color, and let your app shine. All the best!
