AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

uv-build is a build backend for Python projects that integrates with the uv package manager ecosystem, enabling fast, Rust-based project building as part of uv's unified toolchain.

Medium install friction due to platform-specific wheels across 18 architectures (Linux ARM/x86/RISC-V, macOS Intel/ARM, Windows, musl variants). No runtime dependencies simplifies deployment once installed. Active maintenance with latest release 6 days old.

Dual-licensed under MIT OR Apache-2.0, both permissive licenses allowing commercial and private use with minimal restrictions. Choose either license terms when redistributing.

Usage

pip install uv-build==0.12.3

# In pyproject.toml:
[build-system]
requires = ["uv-build==0.12.3"]
build-backend = "uv_build.build"

# Then build with:
python -m build

Requires Python >=3.8; intended for use as a build backend in pyproject.toml, not as a standalone library for direct import.

Verdict: uv-build is a production-ready build backend (Development Status 5) with no known vulnerabilities, permissive dual licensing under MIT OR Apache-2.0, and active maintenance from Astral. Zero runtime dependencies and broad platform coverage make it a lightweight choice for projects adopting uv's ecosystem. Medium install friction reflects its compiled nature across many architectures.

Needs verification
