 summary: sccache is ccache with cloud storage
 description: |
-    sccache is a [ccache](https://ccache.dev/)-like compiler caching tool. It
-    is used as a compiler wrapper and avoids compilation when possible, storing
-    cached results either on [local disk](#local) or in one of [several cloud
-    storage backends](#storage-options).

-    sccache includes support for caching the compilation of C/C++ code,
-    [Rust](docs/Rust.md), as well as NVIDIA's CUDA using
-    [nvcc](https://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html).

-    sccache also provides [icecream](https://github.com/icecc/icecream)-style
-    distributed compilation (automatic packaging of local toolchains) for all
-    supported compilers (including Rust). The distributed compilation system
-    includes several security features that icecream lacks such as
-    authentication, transport layer encryption, and sandboxed compiler
-    execution on build servers. See [the distributed
