Ova Motion as a Rive alternative

If you like how Rive works (vector design, timelines, state machines, runtimes) but want your files on your own device, an editor that works offline, or AI agents that can build scenes, Ova Motion is built for you.

In short

Ova Motion is an alternative to Rive with the same way of working: design, animate, wire a state machine, bind data and ship a small runtime file. It differs in that projects are saved on your device first and work fully offline, it opens .riv files, it has Luau scripts and an MCP server for AI agents, and its runtimes are MIT or Apache-2.0.

Opens .riv
Yes: artboards, animations, state machines and view models
Projects
On your device first, synced to the cloud when you choose
Offline
The desktop app always; the web editor keeps working when the connection drops
Editing together
Live cursors and edits; offline edits merge on reconnect
AI
egg-mcp server and a built-in agent with your own key
Runtime license
MIT or Apache-2.0

What works the way you expect

Coming from Rive, the ideas carry over one to one. Artboards hold the design; animations are timelines of keys; a state machine with inputs, layers, transitions and listeners decides what plays; view models bind data to text, colour and motion; nested artboards reuse pieces; a runtime plays the exported file and your code sets the inputs.

Bringing a Rive file over

  1. Export your file from Rive as .riv.
  2. In Ova Motion choose Open file on the Home screen, or drop the .riv on the window.
  3. Artboards, animations, state machines and view models come in. A few features are converted as closely as Ova Motion allows.
  4. Run it, then export an .egg and play it with an Ova Motion runtime.

When to stay with Rive

If you depend on a runtime Ova Motion does not have yet (React Native, for example), or on a Rive feature the import cannot convert, keep using Rive for that project. Both tools can live side by side.

Questions

Can Ova Motion open Rive files?

Yes. It imports .riv files with their artboards, animations, state machines and view models. A few features are converted as closely as Ova Motion allows.

Can Rive runtimes play .egg files?

No. .egg is Ova Motion's own format, played by Ova Motion's runtimes.

Does Ova Motion work offline?

Yes. Projects are saved on your device first. The desktop app always works offline and the web editor keeps working when the connection drops.

Is Ova Motion a fork of Rive?

No. It is a separate editor and runtime written in Rust, with its own file format.

When Lottie is not enough: interactive animation with Ova MotionLottie is great for playing an animation. When the animation has to react to the user and to your app's data, you want states, listeners and bindings inside the file. That is what Ova Motion makes.Which animation format should your app use?GIF, video, Lottie, animated SVG, CSS and interactive runtime files each fit a different job. Here is how they compare on size, sharpness, interaction and who maintains them.Motion that ships the way you designed it.Draw the interface, animate it on a timeline and decide how it reacts to hovers, taps and data. Developers get the file you made, not a video to copy by hand.State machine (animation)A graph of states and transitions that decides which animation plays.
