Lottie is the rare animation format that gives you real interactivity without costing you page speed. The files are vector JSON, they scale cleanly, and they load in a fraction of the weight of a video.
The practical question is where to get good ones. Here are three libraries worth knowing and what each is actually good for.
1. LottieFiles
LottieFiles is the ecosystem hub. You can create, preview, edit, and export Lottie animations, and there’s a marketplace with thousands of free assets alongside paid ones.
Its real strength is integration. Uploading an animation gets you plugins and handoff paths into website and app builders, which shortens the distance between a designer finishing an animation and a developer shipping it. Designers can also sell their own work there and earn on it.
The weakness is scale. A marketplace with thousands of assets is hard to search when you need something specific to a project — you’ll spend real time filtering.
You need an account. Worth it if you’re working in motion regularly and want access to the wider community of creators.
2. Creattie
Creattie offers hundreds of free Lottie animations with a consistently high quality bar, and — more usefully — assets organised by industry.
The free tier has genuinely practical pieces. Their 404 / Page Not Found animation is a good way to put Lottie on a page that usually gets no design attention at all, and the icon set covers common needs: mail notification, location pin, order tracking, phone.
The customisation is the strong part. Colour, trigger, speed, size, and delay can all be adjusted from the asset page before you download, which means fewer round trips into an animation tool.
The catch: the wider industry-specific library and the integrated editor sit behind a paid membership.
3. Finsweet Lottieflow
If you build in Webflow, Finsweet’s Lottieflow is the most directly useful of the three.
It’s a focused set of UI/UX elements — arrows, checkboxes, scroll indicators, buttons, dropdowns — presented as a minimal, practical collection rather than a sprawling marketplace. For adding polish to interface details, that focus is an advantage.
Best part: no account required to download.
Two limits. The editor needs an account, and the animations come in a single design style. If that style suits your project it’s excellent; if it doesn’t, there’s no variation to fall back on.
Which One to Use
They serve different jobs. LottieFiles is the general-purpose resource with the deepest catalogue. Creattie is the fastest route to polished, industry-specific assets you can tune before download. Lottieflow is the sharpest choice for Webflow UI work.
For most projects, one of the three will cover what you need without commissioning custom animation at all.
Conclusion
Lottie makes a site feel considered without slowing it down — which is the combination that’s usually hard to get.
Stock libraries cover a lot of ground. Where they fall short is anything that has to be recognisably yours: a brand mark in motion, a custom illustration set, an animation carrying your specific product story. That’s where custom work earns its cost.
We know these libraries well enough to tell you when one of them already has what you need — and when your project needs something built. Either way you get a site with animation worth looking at and load times that hold up.
