web2py – Python Web Application Framework

web2py is an open source full-featured, full-stack framework for rapid development of fast, scalable, secure and portable database-driven web-based applications. The framework is developed in Python.

web2py requires no installation and has no configuration files. The framework is designed to work out of the box, offering a web server, database and a web-based IDE that gives access to all the main features. The API includes just 12 core objects, which are easy to work with and memorize. It can interoperate with most web servers, databases and all Python libraries.

web2py uses the WSGI protocol, the Python-oriented protocol for communication between web server and web applications. It also provides handlers for CGI and the FastCGI protocols, and it includes the multi-threaded, SSL-enabled Rocket wsgiserver.

Features include:

  • Offers a rapid development environment.
  • SSL-enabled and streaming-capable web server.
  • Relational database.
  • Database Abstraction Layer that writes SQL in real time.
  • Web-based integrated development environment.
  • Web-based management interface.
  • Internationalization support.
  • Multiple authentication methods.
  • Role based access control.
  • Error logging and ticketing system.
  • Multiple caching methods for scalability.
  • jQuery library for AJAX and effects.
  • Scaffolding application to kickstart development.
  • Security considerations – prevent vulnerabilities including cross site scripting, injection flaws, and malicious file execution. The web2py Database Abstraction Layer (DAL) eliminates SQL Injections. The template language prevents cross site scripting vulnerabilities. Forms generated by web2py provide field validation and block cross site request forgeries. Passwords are always stored hashed. Sessions are stored server-side by default to prevent Cookie Tampering. Session cookies are UUID to prevent session hijacking.
  • Runs with Apache, Nginx, Lighttpd, Cherokee and almost any other web server via CGI, FastCGI, WSGI, mod_proxy, and/or mod_python. It can embed third party WSGI apps and middleware.
  • Interacts with SQLite, PostgreSQL, MySQL, MSSQL, FireBird, Sybase, Oracle, IBM DB2, Informix, Ingres, MongoDB, and Google App Engine.
  • Speaks multiple protocols HTML/XML, RSS/ATOM, RTF, PDF, JSON, AJAX, XML-RPC, CSV, REST, WIKI, Flash/AMF, and Linked Data (RDF).
  • No third party dependencies.
  • Cross-platform support. web2py runs on all major operating systems (Linux, Windows, and Mac), and Google App Engine, Amazon EC2, and almost any web hosting via Python 2.7/3.5/3.6/pypy.
