Flask

Overview

Flask is a lightweight, extensible Python microframework that provides simple routing, views, and templating while keeping a minimal core for quick onboarding and customization.

Core features and highlights

Lightweight core: simple design with no enforced project structure, ideal for rapid prototypes and small apps.
Routing and request handling, built-in development server and debugger, with support for HTTP methods and static file serving.
Supports Jinja2 templating and WSGI utilities from Werkzeug, with a rich extension ecosystem.
Provides Blueprints for modular organization, making it easy to split and reuse code.

Use cases and target users

Beginners choosing a first framework to learn web development.
For rapid prototypes, internal admin tools, microservices, or backends for small-to-medium products.
Suited to Python developers who want full control of the stack and to compose different extensions.

Key advantages or highlights

Highly customizable and extensible: easily add databases, authentication, forms, and more via plugins and extensions.
Well-documented and active community: thorough official docs, plentiful examples, and a mature ecosystem.
From learning to production: small core that can be combined with standard components to build scalable production systems.
