Yes, if you need time-ordered UUIDs and can verify the license. The package has zero dependencies, low install friction, and no known vulnerabilities. However, the aging maintenance status (389 days since release, no recent commits visible) and unclear license metadata warrant a quick check before adopting in production—confirm the MIT License claim and assess whether the implementation meets your compliance requirements.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later.
- No runtime dependencies and a pure-Python wheel make installation frictionless.
- The package is aging (389 days since release) with no recent commits visible in the fact sheet, so maintenance activity is unclear.

What it is and what it does
uuid-extension provides a Python implementation of UUID version 7, a time-ordered identifier format. Unlike earlier UUID versions, version 7 encodes a Unix timestamp in its first 48 bits, making the generated IDs naturally sortable by creation time—a property that improves database index performance and query efficiency when UUIDs are used as primary keys or sort keys.
The library wraps the standard Python UUID object and adds methods to extract the embedded timestamp as either a Unix float or a datetime object, optionally in a specific timezone. It also supports an optional counter parameter to guarantee monotonic ordering within the same millisecond, useful in high-frequency ID generation. The package has no runtime dependencies and installs as a pure Python wheel, making it lightweight to adopt.
Use it for
- Generate sortable primary keys for database tables where insertion order and query performance matter.
- Create time-ordered event IDs in distributed systems where clock synchronization is imperfect.
- Build audit logs or event streams where ID generation timestamp must be recoverable without a separate timestamp column.
- Replace UUID version 4 in applications that benefit from natural time-based ordering without sacrificing uniqueness.
- Implement monotonic ID sequences within millisecond boundaries for high-throughput services.
