Introducing the Rive CLI and RML

Today we're releasing the Rive CLI as a technical preview. It's a command-line tool and a text format for building Rive files with your AI agent. Everything in the video above was built by agents working with a person in the Rive CLI.

Here’s a walkthrough by @Jeff McAvoy 👇

Describe what you want, the agent writes the file, and you see the result as it works. No editor or account needed until you’re ready to publish a .riv. At any time, push the file to the Rive Editor for the full design and animation tools, then pull it back into the CLI.

Rive has always had two files: .rev for the editor, .riv for the runtime. RML is the third: Rive written as text, so you and your agent can read it, write it, and diff it. Start from scratch, or hand it any file you already have.

The CLI is free with no limits during the preview. Files published on the Free plan play a short Rive splash screen before your content; upgrade to remove it. The editor is moving to the same model soon, so the Free plan will export with the splash screen too.
