Exact – a new cross platform UI framework
Exact is a cross-platform application runtime from Expo: interfaces are described in a small declarative language called Contract, data logic is written in TypeScript or Rust, and the compiled plan renders natively on web, macOS, iOS, and Linux without a webview or JS bridge. It is designed to be agent-native, exposing ten uniform operations (tree, screenshot, tap, type, etc.) so an AI agent can build, run, and test apps on every host. It is pre-1.0 with daily changes and no API stability guarantees.
What this means for indie developers：Worth watching for its agent-native cross-platform approach, but pre-1.0 with no API stability makes it unsuitable for production use today.
