The Writer Framework lets you build feature-rich apps by using a drag-and-drop visual editor called the Builder and writing the back-end code in Python. It’s fast and flexible, with clean, easy-to-test syntax. It provides separation of concerns between UI and business logic, enabling more complex apps.Build AI apps with the Writer Framework when:
You need to incorporate external data sources, such as external APIs
You have complex user input that requires custom logic, such as conditions that trigger the use of different prompts
You want to quickly analyze and visualize data using an LLM
Link the event handler and state to the UI seamlessly.
Standard Python packages
Install with a simple pip command.
Version control
Save user interfaces as JSON to be version controlled with the rest of the app.
Flexible editing
Use your local code editor with instant refreshes or the provided web-based editor. Edit the UI while your app is running without needing to click “Preview.”
Minimal overhead
Event handling adds only 1-2ms to your Python code.
Real-time synchronization
Use WebSockets to synchronize front-end and back-end states.
Efficient execution
Non-blocking by default, with asynchronous event handling in a dedicated thread pool.
Customizable elements
No CSS required for customization like shadows, button icons, and background colors.
HTML integration
Include HTML elements with custom CSS using the HTML Element component, which can serve as containers for built-in components.
