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
