Maintaining continuous uptime for a Streamlit application, particularly when deployed on free or shared hosting platforms, often requires implementing strategies to prevent the application from idling or “sleeping” due to inactivity. Many cloud platforms are designed to conserve resources, and automatically suspend inactive applications. This can result in a delayed response or a cold start for users when they next access the application.
Ensuring an application remains responsive is critical for providing a seamless user experience and can be particularly important for applications used in real-time data visualization or applications that need to be readily available. Historically, developers have used various methods, including scheduled tasks or external monitoring services, to periodically ping the application and keep it active. This practice avoids the negative impact of long load times due to server inactivity, maintaining the availability and responsiveness of the deployed application.
