Full Production Bundle

Production Automation Pack ($39)

When automations handle real customer orders, CRM syncs, or AI billing, a single rate-limit error can lose money. The Production Automation Pack adds enterprise reliability patterns to your workflows: idempotency checks, human-in-the-loop Slack approval buttons, error sub-workflows, and dead-letter replay.
