Ccache vs NativeLink

Ccache is a build tool that can reduce repeated compilation work by storing prior results and recognizing when a single-file compilation recurs. It supports compilers such as GCC, Clang and MSVC, and languages including C, C++, assembler, CUDA, Objective-C and Objective-C++, with support varying by compiler and language. Runtime support includes Linux, macOS and native Windows at support level A, and Windows with MSYS2 and other Unix-like platforms at level B. Direct and depend modes can avoid running the preprocessor. Remote caching is possible through adaptable storage backends, with listed helpers for HTTP, HTTPS and Redis protocols. Ccache records cache hit and miss statistics, manages cache size, supports Zstandard compression, and uses BLAKE3 and XXH3 in its hashing and corruption checks. It works with Make, CMake, Ninja and Visual Studio. It is free software under the GNU GPL version 3 or later. Its scope has limits: multi-file compilation, linking and compilations with unsupported flags fall back to the real compiler. The project also cautions that cache misses add overhead and recommends measuring typical workloads.

NativeLink brings remote build caching, remote execution, and observability into a Rust-native platform. Its content-addressed cache deduplicates build artifacts so teams, CI systems, and agents can reuse prior results. Remote execution spreads compilation and tests across worker fleets on AWS, GCP, or bare metal, with GPU, ARM, and Apple Silicon support. Listed build systems include Bazel, Buck2, Siso, Soong, Pants, Goma, BuildStream, and CMake through recc. CI integrations include GitHub Actions, GitLab, Buildkite, and Jenkins; other listed connections include AWS, GCP, Azure, S3, GCS, and Redis. The product also lists integrations with AI coding platforms. It can run as a self-hosted Rust binary. Clients support Linux, macOS, and Windows, while servers support Linux and macOS. The free Open Source tier includes community Slack support. Most of the monorepo uses FSL-1.1-Apache-2.0, but metrics and remote persistent workers are Business Source License modules requiring Enterprise or a separate license for shared production use.
