## What it is
Code Golf is the open-source Go application behind code.golf, a website where players solve programming puzzles ('holes') in the fewest characters across dozens of languages. It runs solutions in sandboxed Docker containers, tracks leaderboards, and can be self-hosted locally.

## Use cases
- practice writing the shortest possible code for programming puzzles
- compete on leaderboards solving algorithmic challenges in many languages
- self-host a code golfing site for a community or classroom
- try out esoteric and mainstream programming languages on small problems
- learn algorithms by implementing Fizz Buzz, Fibonacci, Game of Life and similar holes
- run and validate user-submitted code in isolated Docker sandboxes

## When to choose
- you want to play or host code golf challenges with leaderboards across 60+ languages
- you need a ready-made sandboxed multi-language code execution platform
- you want an open-source, MIT-licensed puzzle site you can contribute to or customize

## When to avoid
- you need a general-purpose online judge for large test suites or production grading
- you want a full IDE or long-form programming environment rather than character-count puzzles
- you cannot run Docker locally and don't want to use the hosted site
