# mozilla/sccache

Sccache is a ccache-like tool. It is used as a compiler wrapper and avoids compilation when possible. Sccache has the capability to utilize caching in remote storage environments, including various cloud storage options, or alternatively, in local storage.

## What it is
Sccache is a ccache-like compiler caching tool that wraps compilers to avoid redundant compilation, storing results locally or in cloud storage backends like S3, Redis, or GCS. It also supports icecream-style distributed compilation with security features and a GitHub Actions integration.

## Use cases
- speed up C/C++ and Rust builds with a compiler cache
- cache compilation results in CI pipelines
- share a build cache across a team via cloud storage
- set up distributed compilation with packaged toolchains
- cache Rust builds on GitHub Actions
- avoid recompiling unchanged code locally

## When to choose
- you build C/C++, Rust, or CUDA projects repeatedly and want faster rebuilds
- you want a shared or remote compilation cache for CI or teams
- you need distributed compilation with authentication and encryption
- you want a ccache alternative with cloud storage backends

## When to avoid
- your builds are fast and caching adds no benefit
- you need caching for languages sccache does not support
- you want a general-purpose build system rather than a cache layer
