## What it is
GLSL Sandbox is a web-based shader editor and gallery for writing, running, and sharing GLSL fragment shaders. It consists of a browser-side editor and a Go server that stores effects in SQLite with thumbnail images.

## Use cases
- experiment with fragment shaders in the browser
- share GLSL shader demos in a public gallery
- self-host a shader gallery server
- learn WebGL shader programming by example
- browse community shader effects for inspiration

## When to choose
- you want a minimal browser-based GLSL playground
- you need a self-hostable shader gallery with moderation
- you want to study or fork community shader code

## When to avoid
- you need a full IDE with debugging and profiling for shaders
- you want to create or edit effects on the official instance, which is in maintenance mode
- you need support for other shading languages like HLSL or WGSL

## Facets
- artifact type: application
- maturity: maintenance
- function: editor, graphics, web-framework
- domain: graphics, web-development, developer-tools
- platform: go, browser, self-hosted
- tags: glsl, shaders, webgl, gallery, creative-coding, web-server, javascript
