Show HN: Krate, AI-made apps as permissioned files for Mac, Windows, and Linux (github.com)

Krate has unveiled a new tool allowing users to create and share AI-generated applications across Mac, Windows, and Linux using a single file format (.krate). This significant development addresses the challenges of app sharing, which often involves complex packaging for different operating systems and unpredictable permissions. With Krate, users can see the specific access an app will require before execution, ensuring control over their files and system resources. The open-source platform currently in pre-alpha allows for easy app creation and distribution while maintaining user trust. The technical backbone of Krate is built on Rust and utilizes WebAssembly through Wasmtime for executing applications. The capability model ensures that apps can only access resources explicitly granted by the user, enhancing security. The current release includes functionalities for creating simple local apps and supports integration with an AI coding agent to automate app creation based on user prompts. While still in development and not yet suitable for untrusted third-party code, Krate shows promise in bridging the gap between traditional desktop applications and web-based solutions, aiming to simplify the app experience without compromising security.
