UpNext has two main service types: Workers and APIs. Workers process jobs from a Redis-backed queue. APIs serve HTTP endpoints powered by FastAPI. You can run them independently or together. Workers execute three kinds of jobs:
  • Tasks — one-off background jobs, submitted programmatically or via the CLI
  • Events — pub/sub handlers that trigger when an event is published
  • Crons — recurring jobs on a schedule
Core features work with just the SDK and Redis. Server features require the UpNext server — see Two ways to run.
