OpenRive: A local-first editor for Rive animations

Description and use

OpenRive enables local, offline editing of Rive animations with web, desktop, and CLI interfaces, and supports AI assistant integration.

Problem

Rive’s editing workflow is usually tied to a hosted product, requiring an account and limiting offline or automated use.

Outcome

OpenRive enables local, offline, and automated editing of Rive animations, preserving interoperability with the wider Rive ecosystem.

Workflow

• Clone the OpenRive repo from GitHub
• Run bun install to install dependencies
• Start the dev server with bun run dev
• Open http://localhost:3000 in a browser to use the web editor
• Use the CLI or MCP server for scripted or AI‑driven workflows
• Deploy the desktop app or self‑hosted Docker stack for production use

Evidence

Rive is a powerful format for interactive motion, but the editing workflow is usually tied to a hosted product.
