## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)

## What it is
Strudel is a web-based environment for live coding algorithmic music patterns, offering a faithful JavaScript port of the Haskell-based TidalCycles DSL. It lets musicians and coders compose and manipulate rhythmic patterns in the browser using Web Audio, and development has moved to Codeberg.

## Use cases
- live code music in the browser
- create algorithmic drum patterns
- perform algorave sets with web audio
- port tidalcycles patterns to javascript
- teach live coding music to students
- prototype rhythmic sequences without installing software

## When to choose
- you want to live code music instantly in a browser with no installation
- you want TidalCycles-style pattern semantics in JavaScript
- you are teaching or learning algorithmic composition

## When to avoid
- you need the full Haskell TidalCycles ecosystem with SuperCollider backend
- you need offline desktop DAW-style production tooling
- you need studio-quality audio rendering rather than pattern experimentation

## Facets
- artifact type: application
- maturity: active
- function: audio-processing, interpreter, programming-language, gui
- domain: audio, web-development, programming-languages, entertainment
- platform: browser, cross-platform
- tags: live-coding, algorave, algorithmic-patterns, web-audio, tidalcycles, music, dsl, sequencer, audio, web-server, javascript
