web.py: makes web apps
Decision gist · record as of 2026-08-14
Yes, if you need a simple, low-friction web framework for prototyping or small applications. The public-domain license, active maintenance, low install friction, and lack of security vulnerabilities make it a safe choice. Not recommended if you need the ecosystem, middleware, or scalability of larger frameworks like Django or FastAPI.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later (supports up to 3.14); earlier versions are not compatible.
- Installation is straightforward with low friction—a pure-Python wheel with three runtime dependencies (cheroot, more_itertools, multipart).
- The project is actively maintained with a recent release (67 days ago) and steady commit activity.

What it is and what it does
web.py is a minimalist web framework that strips away complexity to let you build HTTP applications by mapping URLs to Python classes and functions. It handles routing, request/response processing, and session management with a small API surface and few dependencies—just cheroot for the WSGI server, more_itertools for utility functions, and multipart for form data parsing.
The framework is designed for developers who want to write web applications without the overhead of larger frameworks. It has been actively maintained since 2007 and currently supports Python 3.10 through 3.14. With no known security vulnerabilities and a permissive public-domain license, it's a straightforward choice for simple web projects where you want direct control over routing and request handling.
Use it for
- Build a simple REST API or microservice that routes HTTP requests to handler functions without heavy framework overhead.
- Prototype a web application quickly with minimal setup and configuration before scaling to a larger framework.
- Create a lightweight web server for internal tools, dashboards, or single-purpose applications.
- Learn web framework fundamentals by studying a small, readable codebase with clear request-to-response flow.
- Serve dynamic content with form handling and session management for small-to-medium web projects.
