Python is one of the most widely used programming languages, and many frameworks are available to speed up the development of web apps, APIs, and business applications. Here are some of the top Python frameworks explained in simple terms.
1. Django & Django Rest Framework (DRF)
Django is a strong framework for building big web applications.
- It already comes with authentication system, payment gateway integration and ready admin panel.
- With Django Rest Framework (DRF) we can make REST APIs which are fast, secure and scalable.
- By default Django use dbsqlite3 as database, but you can connect other DB also. Best if you want to build something large like ecommerce, social app or enterprise system.
2. FastAPI
FastAPI is new but very powerful for building high performance APIs.
- Mostly used for AI/ML models, chatbots or apps where speed matter.
- It is lightweight, small and easy to start with.
- It uses async/await, so the API response becomes much faster. Good choice if you want modern API and quick performance.
3. Flask
Flask is a micro framework, meaning very simple and flexible.
- Perfect for small projects, APIs or when you want to keep things lightweight.
- Easy to connect with frontend like React, Vue or Angular.
- You can add custom forms, libraries, authentication as per your need. Mostly used for startups, prototypes and when you need more control on app.
4. Frappe
Frappe is a full-stack open source framework made for business apps.
- Very useful for ERP, CRM, HR and accounting systems.
- It has built-in database models, APIs, UI components so development is very fast.
- You can handle users, roles and permissions easily.
- Also possible to run multiple sites on one server. Best when you want to build enterprise apps like ERPNext.
Conclusion:
- Django/DRF – good for large apps and enterprise solutions.
- FastAPI – best for modern APIs, AI/ML, chatbots.
- Flask – simple and flexible for small apps or quick MVP.
- Frappe – ready for business apps like ERP, CRM, HR.
