doppio
A JVM written in TypeScript that runs Java applications directly in web browsers without plugins.
What is doppio?
Doppio is a Java Virtual Machine (JVM) implemented in TypeScript that allows Java applications to run directly in web browsers without requiring plugins. It solves the problem of browser language barriers by providing a full JVM and POSIX-compatible runtime system entirely in JavaScript/TypeScript. This enables Java code execution in sandboxed web environments where traditional Java plugins are unavailable or deprecated.
Java developers and researchers interested in running Java applications in web browsers, educators creating browser-based Java demos, and web developers exploring alternative runtime systems for the browser.
Developers choose Doppio because it provides a unique, plugin-free way to execute Java in browsers, backed by academic research from UMass Amherst. It offers both browser integration and CLI usage, making it versatile for demos, education, and experimental web applications.
