Relay.app

Relay.app is a workflow automation platform that distinguishes itself from Zapier and n8n with a design philosophy centered on human collaboration within automated processes, rather than fully automated flows that either succeed or fail silently, Relay builds in structured human approval, review, and decision steps at the points in a workflow where human judgment genuinely adds value. A typical Relay workflow might automatically pull new leads from a form, enrich them with company data, and then pause for a human to review and categorize before sending an outreach email, the automation handles the data work, the human handles the judgment call. The AI steps can generate drafts, summaries, or recommendations that humans review before the workflow continues.

This 'human in the loop' model is particularly appropriate for workflows in sales, marketing, and operations where a fully automated path would produce errors at a consequential rate. Relay integrates with 100+ apps including the major CRMs, email platforms, and productivity tools. Plans start at $9/month.

Relay is strongest for small teams and operational leaders who want the efficiency benefits of automation without the risk exposure of fully unsupervised workflows, the appropriate choice when the downside of automation errors is high enough to warrant structured human checkpoints.
