raea

Render Anything Engine (for Anyone)

Tell your AI what to make. Videos, motion graphics, 3D and games, written as React and TypeScript
(the code your AI already writes) and rendered on your own GPU, faster than they play.

raea.io · Made in raea · Why raea · Docs · Releases

Canary. raea changes daily. Releases run on macOS (Apple Silicon), Linux (x86_64) and, new and least tested,
Windows (x86_64). Expect breaking changes, rough edges and gaps in the docs.

Install

curl -fsSL https://raea.io/install | sh

The installer puts the raea command under ~/.raea, links it into ~/.local/bin, and adds raea's agent skills to
~/.claude/skills, so Claude Code (or any agent that reads that folder) knows how to write, render and check raea
work. Run it again to update. The engine is free and needs no account. Tarballs and checksums are on the
releases page.

On Windows 10 or 11, download the zip from the
latest release; its notes give the PowerShell
steps that check, unpack and add it to your PATH. It needs the Microsoft Visual C++ Redistributable (x64), which most
machines already have, and a DirectX 12 or Vulkan GPU driver.

Hello

A composition is a React component that draws a frame for a given moment:

import { AbsoluteFill, Composition, interpolate, registerRoot, useCurrentFrame } from "raea";

function Hello() {
  const f = useCurrentFrame();
  return <AbsoluteFill style={{ background: "#000", color: "#fff", fontSize: 120, opacity: interpolate(f, [0, 20], [0, 1]) }}>Hello</AbsoluteFill>;
}

registerRoot(() => <Composition id="hello" component={Hello} width={1920} height={1080} fps={30} durationInFrames={90} />);

raea render hello.tsx -o hello.mp4

On an Apple Silicon Mac those 90 frames render in about a second. The same file can play live as a game
(raea play), render one frame for an agent to look at (-o frame.png --frame 45), or be checked against a quality
floor (raea check hello.mp4). raea init starts a project, and raea --help lists every verb.

What it does

• Video and motion graphics. Layout, text, Tailwind, SVG and animation, composited on the GPU and encoded in
  hardware where the machine has it. Footage is cut by what's said in it (raea cut), and raea check catches clipped
  text, low contrast, unsafe areas, freezes and loudness problems before anyone watches.
• Games. Input, physics, sound and 3D, played live with raea play, and exported as a program of their own
  (raea export-game).
• 3D. Scenes in TypeScript drawn by Bevy 0.20: cameras, lights, materials, glTF models,
  Gaussian splats, and Bevy plugins compiled into the engine.
• Sound. One mixer for live play and offline render, instruments and effects, and local models for foley and
  instrument notes (raea sao, raea tokensynth).
• Built for agents. Everything it draws stays queryable as data, so an agent can render a frame, look at it, and
  fix what's wrong without a person in the loop.

Use it from your agent

• Agent skills. sdk/skills/raea teaches an agent to write, render and check raea
  compositions; sdk/skills/raea-bevy covers 3D and games. The installer adds both to
  ~/.claude/skills.
• Claude Code plugin. /plugin marketplace add shinyobjectz/raea, then /plugin install raea@raea.
• Craft guides. raea guide prints the floor every edit is held to and the guides for pitches, explainers, stories,
  games, motion, music and layout. raea context PROJECT says what to read before working on a project.

Build from source

Requirements: Rust (stable) and bun. On macOS, Xcode's command-line tools; on Linux, the ALSA, fontconfig and Vulkan libraries.

git clone https://github.com/shinyobjectz/raea && cd raea
cargo build --release -p raea-cli --no-default-features
target/release/raea render sdk/react/bench/games/pong/edit.tsx -o pong.mp4

--no-default-features builds the public engine. The default features add raea's hosted services, which aren't
part of this repository. docs/settings.md lists the settings raea reads.

What's in here

The workspace is layered, from pure building blocks up to the command.

Behaviour specs written in Gherkin (.feature) sit beside the code they describe.
