High performance
One of the fastest Python frameworks for APIs.
Backend
FastAPI
Python APIs with explicit request and response contracts.
FastAPI
FastAPI supports typed API development. We define validation, authentication, and error responses so connected applications have a predictable interface.
Useful for Python integration services where explicit request validation and clear API contracts are central to the work.
Planning your implementation
A technology choice is a delivery decision.
We plan the work needed to build, operate and improve the application, not just the first set of features.
- 01
Review the requirements
We define authentication, request and response structures, background processing needs, and behaviour when a dependency fails.
- 02
Validate the important assumptions
Use a focused prototype or a representative workflow where a technical uncertainty could affect scope. Agree the acceptance checks before building the full solution.
- 03
Plan the handover
API documentation, example requests, deployment settings, and monitoring and error-handling guidance.
Why FastAPI
Why we use FastAPI.
Where FastAPI adds the most value in the projects we deliver.
Automatic documentation
Interactive API docs are generated from the code.
Type-safe
Data validation is built in, reducing errors.
Ideal for AI services
Well suited to serving models and AI features.
Questions
Common questions.
Quick answers to what people often ask us about FastAPI.
When do you use FastAPI instead of Django?
FastAPI suits focused, high-performance APIs and AI services. Django suits full web applications with admin and templates.
Is FastAPI production-ready?
Yes. It is widely used in production for APIs and AI services.
