Streamsync logo Streamsync

Streamsync is an open-source framework for creating data apps. Build user interfaces using a visual editor; write the backend code in Python.

It's fast.

  • Streamsync enables significantly lower response times, when compared to Streamlit.
  • It only runs the user script once.
  • It uses WebSockets to keep frontend and backend states in sync.

It's neat.

  • Streamsync uses state-driven, reactive user interfaces. A data app's user interface is strictly separated from its logic.
  • It uses a consistent yet customisable UI design system.
  • No caching needed; the script runs once and things remain in memory. You can use globals and module attributes to store app-wide data.
  • Predictable flow of execution. Event handlers are plain, easily testable Python functions. No re-runs, no strange decorators.
