Exact debuts agent-native cross-platform UI
Exact is a pre-alpha cross-platform app runtime where developers write typed UI in Contract and data logic in TypeScript or Rust, targeting the web, macOS, iOS, and Linux from one codebase. Its public repository emphasizes fast startup, a compact web runtime, and agent-driven testing across hosts.
Exact’s strongest idea is treating AI agents as first-class developers, not merely autocomplete clients; the performance claims are compelling, but pre-alpha instability makes this a watch-and-test project rather than a production recommendation.
- –Contract provides a small, typed, declarative UI language designed to be easy for agents to generate and reason about.
- –One compiled interface plan targets browser DOM/CSS alongside native Apple and Linux renderers.
- –Built-in agent operations for screenshots, interaction, state, layout, logs, and performance make cross-platform verification unusually concrete.
- –The stated 100 ms startup target and roughly 20 KB web runtime put pressure on heavier JavaScript frameworks.
- –No API stability or backward compatibility exists yet, so early adopters should expect rapid architectural change.
