Jam.py is free and open-source low-code/no-code "full stack" WSGI rapid application development framework for the JavaScript and Python programming language.

Jam.py is event driven low-code development platform for database-driven business web applications, based on DRY principle, with emphasis on CRUD. It is designed to automatically create JavaScript web forms from the underlying database tables, although a form can be created manually if required.

It offers a built-in web server, Application Builder and database access for third-party databases.

Features

• Single distribution which runs with both Python 2.6+ and 3.x
• Can run as a standalone web development server or be used with any web server which supports WSGI
• Built-in GUI builder called Application Builder
• Support for JSON client data (for REST and JavaScript clients)
• Support for popular databases Oracle Database, Microsoft SQL Server, PostgreSQL, SQLite, MySQL, Firebird (database server), SQLCipher
• Extensible authentication mechanisms and role-based access control

Distinctive features

Built-in Application Builder

In the Builder, you can create or modify tables in the database, manage users, load different CSS themes, and add buttons that interact with the underlying operating system. The client side of Jam.py can generate charts with the results of database queries and interact with the server side to produce reports based on OpenDocument templates.

All development, maintenance and remote database administration can be performed via a Builder interface.

Application Builder is strongly influenced by Delphi visual designer:

Delphi style database table data handling on the server and the client, data – interface controls linking, powerful visual interface controls, band oriented report generation based on OpenOffice templates and more.

The following code shows a simple web page that displays "Hello World!" when visited:

task.create_menu($("#menu"), $("#content"), {
    splash_screen: '<h1 class="text-center">Hello World!</h1>',
    view_first: true
});

The above code resides in Task/Client module within the Application Builder.

PythonAnywhere

PythonAnywhere Python 3.x deployment is supported
