Native Apps Your AI Agent Can See and Test

A free guide to Rune, a new native UI framework in Rust by Anomaly: every app can run without a window, so your AI agent renders it to PNG, reads its element tree and clicks through it with a script. Install, first app, the headless commands, a Claude Code prompt for a build, look, fix loop, and the honest limits of a two-week-old project.
