About:
build2 is an open-source, cross-platform C++ build toolchain that provides a package manager and build system in one. It emphasizes reproducible builds and hermeticity by strictly controlling dependencies and environment variables. The toolchain includes its own package manager, build system, and toolchain utilities, offering a cohesive alternative to piecing together separate solutions.

Key Features:

Integrated package manager and build system
Strict reproducibility and hermetic builds
Cross-platform support (Linux, macOS, Windows)
Declarative build specifications
No external dependencies

Use Cases:

Managing dependencies and building C++ projects across different platforms
Establishing reproducible build environments for CI/CD pipelines

Alternatives:

CMake – CMake is a widely used meta-build system but relies on external package managers like Conan or vcpkg, whereas build2 provides an integrated solution.
Bazel – Bazel offers similar reproducibility and monorepo support but is primarily focused on the Google ecosystem and has a steeper learning curve.
