What is it?
Django vs FastAPI comparison for teams choosing a stack — evaluating MVP timeline, cost, hiring, and maintainability with optional GreeLogix architecture review.
Technology Comparison
Django vs FastAPI
Django gives you admin, ORM, and auth out of the box for full web apps; FastAPI gives you async speed and automatic docs for APIs and ML serving. Many products use both — here's how to choose.

Common Challenges
Problems We Help Buyers Solve
Teams evaluating django vs fastapi typically hit these blockers before finding a reliable partner.
Analysis paralysis
Teams debate stacks for months while competitors ship.
Biased vendor advice
Agencies recommend what they sell — not what's best for your constraints.
Hidden migration cost
Switching frameworks mid-build can exceed greenfield estimates.
POC that never becomes production
Spikes prove feasibility but leave no path to maintainable code.

Comparison table
Django vs FastAPI
Django ships full web apps with admin, ORM, and auth; FastAPI ships fast async APIs with typing and auto docs. Many products use both.
| Dimension | Django | FastAPI | Recommendation |
|---|---|---|---|
| Best for | Full web apps, admin, SaaS | Async APIs, ML serving, microservices | Django app + FastAPI inference is common |
| Admin & ORM | Batteries-included admin + ORM | Bring your own (SQLAlchemy) | Django when admin saves weeks |
| Performance | Solid; sync-first | Async-native, high throughput | FastAPI for concurrency/ML |
| Typing & docs | DRF serializers | Pydantic + automatic OpenAPI | FastAPI for typed contracts |
| Time to MVP | 8–12 weeks with admin | 8–12 weeks API-first | Pick per primary workload |
