Does BoringCache replace sccache?

No. sccache still wraps the compiler and decides cache hits. BoringCache provides the shared remote cache endpoint.

Is this only for Rust?

No. sccache is commonly used for Rust, C, and C++ compiler outputs.

sccache remote cache

Share compiler results across machines.

Give Rust, C, and C++ builds access to one shared sccache store. Reuse eligible compilations from CI, containers, and local development.

How BoringCache fits your build.

Compiler reuse

sccache decides whether an invocation can use a stored result.

Shared storage

Matching compiler-cache data is stored once in the workspace.

Visible activity

Inspect compiler-cache reads, writes, and transfers.

Use compiler caching on its own or with Cargo.

The sccache adapter connects compiler caching to your command. For Rust builds that also need dependency and target-state reuse, use the Cargo integration.

See compiler-cache reuse in each build.

Inspect cache hits, misses, and transfers from sccache in your workspace.
