zapcc is a caching C++ compiler based on clang that speeds up builds using an in-memory compilation cache in a client-server architecture. The zapcc client reuses a persistent zapccs server process to remember compilation information between runs.

Use cases

• speed up c++ compilation times
• cache c++ builds like ccache but faster
• reduce incremental build times in large c++ projects
• drop-in clang replacement with caching
• avoid recompiling unchanged headers with precompiled header caching

When to choose

• you build large C++ codebases repeatedly and want faster incremental builds
• you already use clang and want a drop-in faster replacement
• you have RAM to spare for an in-memory compilation cache server

When to avoid

• you need MSVC (Visual C++) target binaries, which are unsupported
• memory-constrained environments where a resident compiler server is impractical
• you need actively maintained tooling - last release was 2020
• you need non-x64 or exotic platform support
