01
Limited integrations with non-Python ecosystems
Ruff is primarily designed for Python and lacks native support or seamless integration with other languages and tools.
02
Complex setup for CI/CD pipelines
Configuring Ruff within various CI/CD systems requires manual configuration and can be error-prone without clear documentation on best practices.
03
Performance degradation with large codebases
While generally fast, Ruff's performance may drop significantly when processing very large Python projects due to memory constraints and increased complexity.
