Background Jobs & Scheduling

Why not Redis + Sidekiq or Celery? Oban gives you robust, Postgres-backed job processing with scheduling, priorities, rate limiting, and a web UI — no Redis required. For recurring tasks, Quantum provides cron-like scheduling. For simple async work, GenServer and Task are built into OTP. The BEAM's lightweight processes mean you don't need external worker infrastructure.
