What Mosso is
Pick a free Lottie animation, make it yours in the editor or with your own AI, and export it anywhere for free.
Three ways in
Three ways to make an animation
They all run on the same engine and your brand kit, so you can start one way and finish another.
Templates and library
Templates are whole pieces you edit: social posts, launch videos, logo reveals. The library has the small parts, like icons, loaders, stickers and backgrounds. Templates and icons can use your brand colours. Illustrations keep their original colours, which you can edit.
The full editor
When you want control, open the timeline. Keyframes on supported properties, easing curves and springs, text that moves letter by letter. Undo, shortcuts and autosave work the way you'd expect.
See the editorLibrary
Find your first free animation
Open any animation in the editor and change its words, colours or keyframes. Download it for free with an account, or export it from the editor.
Brand kit
Save your brand colours and fonts for loaders, posts and logo reveals. Add your logo in the editor.
Your kit holds your logo, colours and fonts, and how you like things to move, from calm to snappy. Pick a sample look and watch these change.
Features
Built for Lottie, and it still makes video
Lottie is the format for animation on websites and apps. Check the export in the player or app where you will use it. Mosso warns about known format limits. Need a video instead? Same project, different export.
Small files
Vector animations can stay sharp when resized. File size depends on the animation; dotLottie compresses the Lottie data.
Sharp at any size
It's shapes, not pixels, so the same file looks crisp on a phone and on a 4K monitor.
Plays where your site lives
Plain websites, React, Webflow and Framer, and the official players for iOS and Android.
One-click motion
Fade, rise, pop, bounce and float, staggered across your layers.
A real timeline
Keyframes, easing curves and springs, for when a preset isn't quite it.
Text that moves
Headlines that come in letter by letter, word by word or line by line.
Effects you can edit
Confetti, fireworks, snow, sparkles and loaders, all made of normal layers.
Your own things
Choose from the font list, then add your logo as SVG and your images.
The basics done right
Undo, keyboard shortcuts and autosave. Or start from a blank canvas and draw.
Export
Every export format is free
Download Lottie, dotLottie, video, GIF, transparent WebM, animated SVG or PNG frames. There is no Mosso watermark.

Do I need to know animation?
No. Ask for what you need or pick something from the library, type your words and export it. The timeline is there if you ever want more control.
Is Mosso only for Lottie?
No. Lottie is what Mosso does best, since it's the right format for websites and apps, but the same project also exports MP4, GIF, transparent WebM and PNG frames.
Are the library animations really free?
Yes. Download the Lottie or dotLottie file from any library page, with a free account, and use it in your own projects and client work, including commercial work. You can't resell them as templates or stock files. Create a free account to download up to 50 library animations a day. The limit resets at midnight UTC. Each download is one animation.
Can I use what I make for my business?
The editor, every export, templates and library are free. Use mosso-mcp with Claude Desktop, Claude Code or Cursor. The connector runs on your computer and uses your own AI account. Create a free account to download up to 50 library animations a day. The limit resets at midnight UTC. Each download is one animation.
Where does my work live?
In your browser. If you make an account, your projects also sync, so you can open them on any computer.
Does it work with Figma, Canva or After Effects?
Yes. Copy SVG from Figma and paste it into Mosso. Export GIF or MP4 files for Canva and Adobe Express, or import your logo and images. For video work, export PNG frames, unzip them, and import the sequence into a compatible video editor.
What is Lottie?
A small animation file that websites and apps play as sharp vectors at any size. dotLottie is the same animation in a smaller, zipped file.
How is Mosso different from Jitter?
Jitter is a good tool, and it's made for designers. Mosso is for everyone else. You can ask for an animation in plain words or start from a library you can edit, your brand gets applied for you, and Lottie comes first, with video and GIF alongside.
