If you're running a Python app on Vercel, Railway, Render, or Fly.io, you've run into this - there's no persistent process, so you can't use cron, APScheduler, or Celery workers the traditional way. Most developers end up using the platform's built-in scheduled tasks — which work fine until they silently stop running and nobody notices for three days. I built Tickstem to solve this, and just shipped a Python SDK. The silent failure problem Here's the thing about cron jobs: they fail in two ways.
