🚀 Jam.py | Build internal tools in minutes, run any Python code from the Browser input

What is Jam.py?

Jam.py is a low-code, web-based framework that automatically generates the front-end for your web app. It works seamlessly with both existing databases and newly created ones, creating forms, tables, filters, sorters, and full CRUD interfaces—so you can focus on your data and business logic.

The framework uses Python for backend logic, giving you the flexibility to extend your app with custom business rules, validations, file import/export tools, data processing, or even data visualizations. This provides full control over how your application behaves behind the scenes—combining low-code convenience with Python’s power.

How does it work?

Connect to a database – Use SQLite, PostgreSQL, MySQL, Firebird or Oracle
Define your tables – Use the built-in editor to create fields or import schema
Jam.py generates the UI – Get forms, grids and navigation instantly
Customize your app – Use Bootstrap, JS/CSS and logic scripting with Python
