Automation that stops and asks a human before it does the irreversible thing.

Pricing
Verified 14 Jul 2026· sourceOverview
Relay.app's distinguishing idea is that full automation is often the wrong goal. It builds human-in-the-loop approval directly into the workflow: a step can pause, route a draft to a person, wait for them to edit or approve, then continue. For anything customer-facing — outbound replies, refunds, publishing, anything with a blast radius — that is a far more sensible pattern than letting an LLM fire and hope. Underneath, it is a competent modern automation tool with a couple hundred app connectors, an AI-assisted builder, and sane operational touches like automatic retries and API rate-limit handling, which many competitors leave you to solve yourself. Pricing is more accessible than most of the category, and there's a real free tier. The trade-offs: the connector catalogue is a fraction of Zapier's, the free plan's step allowance is small enough that it is more a trial than a home, and the approval model adds latency by design — if what you want is a workflow that runs unattended at 3am, the tool's best feature is dead weight.
