LottieLab

LottieLab is a modern, browser-based editor dedicated to creating and editing Lottie animations — the lightweight, scalable, vector-based animation format that has become a web and app standard. Lottie files are beloved by developers because they're tiny, crisp at any resolution and easy to drop into products, but creating them traditionally meant wrangling After Effects and plugins. LottieLab makes that whole process visual, accessible and fast.

With LottieLab, you can design and animate directly in a friendly timeline-based editor, or import existing Lottie files and tweak them — change colors, timing, layers and behavior — without touching the underlying JSON or going back to complex motion software. This is a genuine relief for designers and developers who frequently need to customize animations they find or receive, but who don't want to maintain a heavyweight After Effects workflow just to change a color or adjust a loop.

Beyond editing, LottieLab supports building animations from scratch with vector tools, adding interactivity, and exporting clean Lottie files ready for the web, iOS, Android and frameworks like React. Collaboration features let teams work on animations together, and the export options ensure the output stays lightweight and performant — preserving the key advantages that make Lottie so popular. For product teams, designers and developers who use Lottie animations for micro-interactions, loaders, onboarding and delightful UI details, LottieLab fills an obvious gap: a purpose-built, modern tool for the format, making it dramatically easier to create, customize and ship beautiful animations without the traditional friction. It's a focused tool that does one important thing exceptionally well.
