Been seeing lots of comparisons between Rive and After Effects.
I want to set the record straight: Rive is not trying to replace or compete with After Effects.

Rive's state machines let designers build real interactions (not just mockups or prototypes).
We think this is an important creative aspect that is missing in modern workflows.👇

Got several requests to write about Rive vs Lottie.
Though we’re working to solve a bigger problem, Rive already does all the things Lottie can do and more.
Rive is faster, smaller, and built for the interactive era.

Most of you know Rive for its real-time animation capabilities… but Rive is also a complete UI solution for games.
We think it's the UI solution game engines have been missing.
Here's what you're going to be seeing in the coming months. 👇

Want to learn more about Rive? 👇
At its core, Rive is a new graphics format. It’s a type of graphic that can react, animate, and change itself at any moment.
The format (.riv) and its players are open. As a business, we offer a suite of design and dev tools to support it.

This week a customer asked us to rebuild a 17.1 MB Lottie file in Rive.
🤔 The 17.1 MB Lottie file optimizes to 13 MB with LottieFiles' JSON optimizer.
🙌 The Rive file is 217 KB.
All about Lottie optimization!
After 4+ years of R&D on the Lottie format, we’ve developed a way to reduce scripts & images within a Lottie.
Now with our Lottie Optimizer, you can further reduce its file size for better performance.
Here’s how:

Rad example from Alex. Notice the thickness of the font animates (variable axis). This is all done with real-time text that can be dynamically manipulated at runtime.
This is not a prototype or a mockup.
This is a runtime-ready asset.
