Applets are officially, completely removed from Java 26, coming in March of 2026. This brings to an official end the era of applets, which began in 1996. However, for years it has been possible to build modern, interactive web pages in Java without needing applets or plugins. TeaVM (
https://teavm.org) provides fast, performant, and lightweight tooling to transpile Java to run natively in the browser. And for a full front-end toolkit with templates, routing, components, and more, Flavour (
