## What it is
Ccache is a fast compiler cache that speeds up recompilation by caching previous compilations and detecting when the same compilation is being done again. It supports GCC, Clang, MSVC and similar compilers for C, C++, CUDA, Objective-C and assembler, with local and remote cache backends.

## Use cases
- speed up c++ recompilation
- cache gcc builds
- speed up ci build times
- cache clang compilations
- share a compiler cache across a team
- avoid recompiling unchanged c files
- speed up msvc builds

## When to choose
- you build C/C++/CUDA projects repeatedly and want faster rebuilds
- you want to cut CI compile times with a local or shared cache
- you use GCC, Clang, or MSVC and want a drop-in compiler wrapper

## When to avoid
- your project is not compiled with a supported compiler
- you need caching for interpreted languages like Python or JavaScript
- your build is dominated by linking or tests rather than compilation
