Guide: Deploy Python Bots on Koyeb and Heroku Using StayPresent Library

Developers deploying Python bots on Koyeb and Heroku face platform-specific challenges around port binding, process types, and health checks. The StayPresent library addresses these by providing a unified configuration that works across both platforms without platform-specific code branching. On Heroku, a Procfile with a 'web' process type is required, while Koyeb supports Git or Dockerfile-based deployments, both injecting a PORT environment variable the app must bind to. StayPresent's built-in /health route satisfies Koyeb's HTTP health checks, and a self-ping cron pattern prevents Heroku dynos from sleeping due to inactivity. The same main.py file, using StayPresent's port binding and crash-restart options, can run unchanged across Koyeb, Heroku, Render, and Railway.
