mold is a high-performance drop-in replacement for traditional Unix linkers like GNU ld, gold, and LLVM lld. It dramatically reduces link times for large C, C++, and Rust programs, improving developer productivity in debug-edit-rebuild cycles.

Use cases

  • speed up linking of large C++ executables like Chromium or Clang
  • reduce build times in rapid debug-edit-rebuild cycles
  • replace GNU ld or lld as a faster linker
  • link Rust programs faster
  • cut CI build times for large native projects

When to choose

  • you link large native binaries and link time dominates your build
  • you want a drop-in replacement for ld, gold, or lld with no workflow changes
  • you develop on Linux or macOS with supported architectures like x86-64 or ARM64

When to avoid

  • you target platforms or object formats mold does not support (e.g., PE/COFF Windows binaries)
  • you need a linker for embedded toolchains with unusual ELF quirks
  • your toolchain pins a specific linker's extensions or behavior
