BASIC-256 is a beginner-friendly programming language that makes learning to code fun with graphics, math, and immediate results.
This is the real BASIC-256 — the same interpreter as the desktop app, compiled to WebAssembly and running in a browser tab. Nothing to install.
Opens run.basic256.org in a new tab and downloads roughly 16 MB the first time — best on a desktop browser.
The desktop build gives you the complete IDE: syntax highlighting, a step debugger, separate text and graphics output panes, and full speed for animation-heavy programs like the one shown here.

Create drawings, animations and visual projects easily.
Great for learning math and problem solving.
Works on Windows, Linux, macOS and the Web.
Free, open source and supported by a friendly community.
A maintenance release on top of 2.1.0: programs run about twice as fast, and the browser version now remembers your program across a refresh.
The first stable release of the 2.1 series: Qt 6, a browser build, Apple Silicon and Intel Macs, a module library and a new look.
The documentation site has its own domain, and the app now points at it from the About box, Online help and F1.
