ugBASIC

An isomorphic language
for retrocomputers

What's News Get Started

ugBasic is isomorphic

A BASIC dialect specialized in programs that are very efficient "by design" on various 8-bit platforms, without the need for "fine tuning" them and without compromises of other dev-kits.

Download the compiler

You can download the official ugBASIC compiler (ugbc), which directly converts a program written in ugBASIC into the assembly equivalent for the given CPU / computer. The compiler is free, open source and licensed under the Apache 2.0 license. You can download or recompile the latest version from the GitHub repository.
