Lottie vs Rive: Choosing an Animation Format for Interactive Apps

Rive is the format most commonly brought up as a Lottie alternative, and the two solve a genuinely different part of the problem rather than competing on the same axis.

Where the workflows differ

• Lottie is exported from After Effects (via the Bodymovin/LottieFiles plugin) or built in Figma with a Lottie export plugin — it plugs into design tools teams already use.
• Rive animations are built directly in the Rive editor, a purpose-built tool for interactive motion design that isn't a plugin on top of an existing app. Adopting it means learning a new tool, not exporting from one you already know.

Interactivity: scripted vs. built-in

This is the biggest practical difference. With Lottie, hover/press/drag-driven behavior has to be wired up by hand in your own JavaScript — calling playSegments or goToAndStop in response to events, as covered elsewhere in this guide. Rive's editor has a built-in state machine: a designer can define inputs (a boolean, a number, a trigger) and wire transitions between animation states directly in the tool, so a button press or a drag gesture can drive complex animation logic without a developer writing per-interaction glue code.

Runtime and file size characteristics

Rive's runtime is a compact native/WebAssembly engine purpose-built for real-time playback, which tends to make it well suited to animation-heavy, game-like interfaces. Lottie's JSON-plus-JavaScript-player approach is simpler to reason about and debug (it's just data you can open in a text editor, as covered in our guide to reading raw Lottie JSON) but leans more on your own code for anything beyond linear playback.

Ecosystem and tooling maturity

Lottie has years of momentum behind it: a huge library of free and paid animations on marketplaces, broad platform support (iOS, Android, web, React Native, Flutter), and most motion designers already know the After Effects export workflow. Rive's ecosystem is smaller and newer, though it's grown quickly and covers the major platforms as well.

Practical decision guide

Stick with Lottie if your team already has an After Effects/Figma motion design pipeline, you rely on marketplace assets, or your animations are mostly linear (load once, play, maybe loop) rather than deeply state-driven.

Consider Rive if you're building an interface with a lot of interaction-driven animation — game-like transitions, complex multi-state UI controls — and can invest the time in learning its editor; the built-in state machine can replace a meaningful amount of custom animation-control code.
