## What it is
Bonzomatic is a live shader coding tool where you write a 2D fragment/pixel shader while it runs in the background. It was built as the standard workhorse for demoscene Shader Showdown live coding competitions.

## Use cases
- live-code fragment shaders on stage at demoscene competitions
- practice shader programming with instant visual feedback
- run head-to-head shader coding battles with a standardized tool
- learn GLSL or HLSL by experimenting in real time
- visualize audio-reactive effects using FFT input textures

## When to choose
- you need a battle-tested, standardized tool for live shader competitions
- you want a minimal editor focused purely on fragment shader live coding
- you need cross-platform support with DirectX and OpenGL backends

## When to avoid
- you want a full-featured daily shader IDE with includes, debugging, or project management
- you need vertex shader or full pipeline editing rather than 2D fragment shaders
- you want a general-purpose code editor

## Facets
- artifact type: application
