A web-based P2P collaborative editor for live coding sounds and images. Similar to Etherpad, but focused on code evaluation for livecoding. Multiple separate slots for different languages and tools. Supports REPL plugins which allow users to locally evaluate code from interpreters (like Haskell, Ruby, Python, etc.) Supports web plugins for languages embedded in editor (like Hydra, p5, and Strudel).

Hydra is a platform for live coding visuals, in which each connected browser window can be used as a node of a modular and distributed video synthesizer.

A software synth designed with livecoding and codejamming in mind. Optimized for the Raspberry Pi. FOSS Designed with classrooms in mind but certainly not necessary. Looks like a clean and straightforward programming language. You can definitely perform with it. There's a free to download ebook about it available on the usual appstores. soundsculpting Can also play back samples with it, not just building synth patches. Available in the Raspbian default package repository.
