uuid-utils
Fast, drop-in replacement for Python's uuid module, powered by Rust.
Decision gist · record as of 2026-08-14
Yes, if UUID generation performance matters in your application or if you need UUID versions 6, 7, or 8. The permissive license, active maintenance, zero vulnerabilities, and API compatibility make it a low-risk upgrade. Use the compat module if your framework requires exact standard-library UUID types.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; some frameworks may require the compat module to return standard-library UUID instances.
- Medium install friction due to compiled wheels; prebuilt binaries available for common platforms (macOS, Linux, Windows) and Python 3.10–3.14, but installation may require compilation on unsupported architectures.
- Project is actively maintained with recent releases.

What it is and what it does
uuid-utils is a Rust-powered implementation of UUID generation that supports all standard UUID versions (1, 3, 4, 5, 6, 7, 8) with an API compatible with Python's uuid module. It can be imported as a direct replacement and includes a compat mode that returns standard-library UUID instances for frameworks requiring exact type matching.
The library is actively maintained, supports Python 3.10 through 3.14, and has no runtime dependencies. Prebuilt wheels are available for most common platforms, though some architectures may require compilation. It carries a permissive BSD-3-Clause license and has no known security vulnerabilities.
Use it for
- Generate time-ordered UUIDs (version 7) for database primary keys that maintain insertion order.
- Use in frameworks requiring standard-library UUID instances via the compat module.
- Generate namespace-based UUIDs (versions 3 and 5) for deterministic ID creation from names or data.
- Integrate into systems where UUID generation throughput is a performance concern.
- Access UUID versions 6, 7, and 8 not available in the standard library.
