## Development { #development }

By the time I started creating **FastAPI** itself, most of the pieces were already in place, the design was defined, the requirements and tools were ready, and the knowledge about the standards and specifications was clear and fresh.

## Future { #future }

By this point, it's already clear that **FastAPI** with its ideas is being useful for many people.
