Common questions

What makes Relay.app different from Zapier?

Relay.app is designed for workflows that require human judgment, approvals, or team handoffs within automated processes. Zapier focuses on fully automated, no-human-intervention flows.

Does Zapier support human approval steps?

Zapier can be set up to pause and send approval requests via email or Slack, but it is not natively designed for human-in-the-loop workflows the way Relay.app is.

Is Relay.app good for approval workflows?

Yes. Relay.app is specifically designed for workflows that include human approval steps, making it excellent for procurement, content review, expense approval, and similar processes.
