Pros & cons
Advantages
- Free tier allows you to build and test prototypes without paying upfront
- AI features can significantly reduce time spent on repetitive design tasks
- Straightforward interface means less of a learning curve than some alternatives
- Good for testing complex interactions and user flows before development
Limitations
- Collaboration features and advanced capabilities require paid plans, which may not suit solo designers on a budget
- Less suitable for static mockups or simple wireframes where the advanced features aren't needed
Use cases
