Hosting Flet Applications

Overview

Flet applications rely on WebSockets for real-time, partial UI updates and event communication between the client and the Flet program.

Key Considerations

  • **WebSocket Support**: Ensure the hosting provider explicitly supports WebSockets. Some providers may restrict or offer WebSockets as a premium feature. Be aware of potential proxy configurations that might terminate WebSocket connections due to timeouts; Flet includes reconnection logic, but this can negatively impact user experience.
  • **Latency**: Minimize latency by selecting hosting providers with multiple data centers. Deploying your Flet app in a data center geographically closer to the majority of your users will improve responsiveness, as UI updates and events are transmitted frequently.
