Codename One Brings Java to Embedded Linux With Smaller Memory Footprint

Codename One, an open-source framework for building native apps from a single Java or Kotlin codebase, now runs on embedded Linux. The article claims its UI drew an animated gauge in 18 MB of memory without a GPU, roughly a twentieth of what a Chromium kiosk needed. A headless backend reportedly handled 379,900 requests per second on two cores, about 1.3 times Rust's axum framework. The framework draws in software by default via DRM/KMS or the Linux frame buffer, avoiding X11 or Wayland, and the project does not charge royalties.
