cuid
Fast, scalable unique ID generation
Decision gist · record as of 2026-08-14
No. The package is abandoned (last commit May 2023, no releases for over a year) and the CUID standard itself is officially deprecated in favor of CUID2. While it has no known vulnerabilities and high installation friction is its only technical drawback, choosing a deprecated standard for new code creates long-term maintenance risk. Use CUID2 instead unless you are maintaining legacy code already using this package.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Installation friction is high due to source-only distribution.
- The package is abandoned—last commit was 2023-05-21 and no releases since 2023-03-06—so expect no maintenance or security updates going forward.

What it is and what it does
cuid.py is a Python port of the JavaScript CUID library, generating portable, sequentially-ordered unique identifiers optimized for horizontal scalability and speed. It has no external dependencies beyond the standard library. The package generates IDs that are designed to be collision-resistant and suitable for distributed systems where many machines may be generating IDs concurrently.
However, the package is abandoned and the CUID standard itself has been officially deprecated in favor of CUID2. While the implementation works and has no known vulnerabilities, it receives no maintenance or updates. If you are starting a new project, the maintainers recommend using CUID2 instead.
Use it for
- Generate unique identifiers for database records in horizontally-scaled web applications.
- Create collision-resistant IDs for distributed systems where multiple services generate identifiers independently.
- Build audit trails or event logs that require sortable, sequentially-ordered unique identifiers.
- Replace UUID/GUID generation when you need better performance and horizontal scalability properties.
