Estuary is a platform for collaboration and learning through live coding. It enables you to create sound, music, and visuals in a web browser. Key features include:

built-in tutorials and reference materials
a growing collection of different interfaces and live coding languages
support for networked ensembles (whether in the same room or distributed around the world)
text localization to an expanding set of natural languages
visual customization via themes (described by CSS)

TOPLAP is an organisation founded in 2004, to explore and promote live coding. Live coders expose and rewire the innards of software while it generates improvised music and/or visuals.

Faust (Functional Audio Stream) is a functional programming language for sound synthesis and audio processing with a strong focus on the design of synthesizers, musical instruments, audio effects, etc. Faust targets high-performance signal processing applications and audio plug-ins for a variety of platforms and standards.

FoxDot is an easy-to-use Python library that creates an interactive programming environment and talks to the powerful sound synthesis engine, called SuperCollider to make music. FoxDot schedules musical events in a user-friendly and easy-to-grasp manner that makes live coding easy and fun for both programming newcomers and veterans alike.

Open-source library and tools for audio and music analysis, description and synthesis

Ampache is a web based audio/video streaming application and file manager allowing you to access your music & videos from anywhere, using almost any internet enabled device.

Ampache's usefulness is heavily dependent on being able to extract correct metadata from embedded tags in your files and/or the file name. Ampache is not a media organiser; it is meant to be a tool which presents an already organised collection in a useful way. It assumes that you know best how to manage your files and are capable of choosing a suitable method for doing so.

ixi audio is an experimental project concerned with the creation of digital musical instruments and environments for generative music.

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.

meSing.js is a JavaScript singing synthesis library that uses the Web Audio API's DSP capabilities in conjunction with the meSpeak.js speech synthesis library to provide a vocal synthesizer for the web.

Tone.js is a Web Audio framework for creating interactive music in the browser. The architecture of Tone.js aims to be familiar to both musicians and audio programmers looking to create web-based audio applications. On the high-level, Tone offers common DAW (digital audio workstation) features like a global transport for scheduling and timing events and prebuilt synths and effects. For signal-processing programmers (coming from languages like Max/MSP), Tone provides a wealth of high performance, low latency building blocks and DSP modules to build your own synthesizers, effects, and complex control signals.

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.

Flocking is a JavaScript audio synthesis framework designed for artists and musicians who are building creative and experimental Web-based sound projects.

A self-hosted, web-based application for stream your music, everywhere.

An interface for the Web Audio API that supports rhythms, multiple instruments, repeating sections, and complex time signatures.

Streeme can serve music to most HTML5 compliant browsers and smartphone handsets using the computer you already own.
