- 02
Vendor lock-in risks
Custom project setup and dependency management specific to uv may complicate migration to other tools.
- 03
Complex setup process for non-standard projects
Projects with unconventional structures or requirements might require significant configuration, which can be cumbersome and error-prone.
- 04
Dependency on Rust ecosystem for performance gains may introduce instability
Performance benefits from Rust could be offset by potential compatibility issues with rapidly evolving Rust libraries.
