raea renders videos, motion graphics, 3D and games written in React and TypeScript on your own GPU, without a browser
raea (Render Anything Engine) is a free engine, built in Rust on Bevy, that renders compositions written in React and TypeScript straight on your GPU instead of through a browser. It is made for coding agents, which can render a frame, check it and fix the code, and it runs on macOS (Apple Silicon), Linux and Windows.
What it does
It covers layout, text, SVG and animation composited on the GPU with hardware encoding, footage cut by what is said in it (`raea cut`), 3D with cameras, lights, glTF models and Gaussian splats, games you can play live, and a mixer with local models for foley and instrument notes. `raea check` flags clipped text, low contrast, unsafe areas, frozen frames and loudness problems before anyone watches.
Worth knowing
The README says 90 frames of a 1080p composition render in about a second on an Apple Silicon Mac; the creator's claim of 10 to 20 times faster than Remotion and HyperFrames is not independently tested. It is a canary release that changes daily, Windows is the least tested platform, and the licence is FSL-1.1-ALv2: free with no account, but not for building a competing engine, and each version becomes Apache 2.0 after two years.
