Rive is an engine that lets developers build games, apps, and interactive interfaces using a coding agent and a visual editor. It supports macOS, Windows, and Linux and can be used as a full engine or integrated into existing projects. What sets Rive apart is its combination of an AI‑driven CLI that generates initial assets from prompts and a professional editor for drawing, rigging, animating, and adding interactivity. Open‑source runtimes and no royalties make it easy to ship across platforms.
