When NOT to use CodeWhale
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- - Avoid CodeWhale if your project is not aligned with or does not benefit from being developed in Rust or requires extensive functionalities that focus on web-based interfaces rather than CLI/TUI.
- - If the project specifically needs features or supports languages that are more prevalent in competitor tools, such as Python for a wide range of AI agent development frameworks.
