Sonic Pi is a new kind of musical instrument. Instead of strumming strings or whacking things with sticks - you write code - live.

Sonic Pi is a complete open source programming environment originally designed to explore and teach programming concepts within schools through the process of creating new sounds.

In addition to being an engaging education resource it has evolved into an extremely powerful and performance-ready live coding instrument suitable for professional artists and DJs.

Gibber is a live coding environment for the web browser, using the Gibberish.js audio engine, the CodeMirror code editor library and wrapping Three.js for 3d graphics and shader support. Version 2 of Gibber features a much more efficient audio engine, some interesting mapping abstractions and a server/database backend for publishing and browsing files and collaboratively live coding.

TidalCycles (or Tidal for short) is a language for live coding patterns.
It allows you to make musical patterns with text, describing sequences and ways of transforming and combining them, exploring complex interactions between simple parts.

A 3D game engine for livecoding worlds into existence.

Fluxus is a rapid prototyping, playing and learning environment for 3D graphics, sound and games. Extends the Racket language with graphical commands and can be used within it’s own livecoding environment or from within the DrRacket IDE.

Overtone is an open source audio environment designed to explore new musical ideas from synthesis and sampling to instrument building, live-coding and collaborative jamming. We combine the powerful SuperCollider audio engine, with Clojure, a state of-the-art lisp, to create an intoxicating interactive sonic experience.
