Relay.app

Relay.app was a workflow automation platform that distinguished 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 built in structured human approval, review, and decision steps at the points in a workflow where human judgment genuinely adds value. A typical Relay workflow would 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 could generate drafts, summaries, or recommendations that humans reviewed before the workflow continued. This 'human in the loop' model was particularly appropriate for workflows in sales, marketing, and operations where a fully automated path would produce errors at a consequential rate.

Relay integrated with 100+ apps including the major CRMs, email platforms, and productivity tools. Plans started at $9/month before Relay.app announced it is shutting down, with no new signups or upgrades accepted. Relay was strongest for small teams and operational leaders who wanted the efficiency benefits of automation without the risk exposure of fully unsupervised workflows. The service closed entirely on September 14, 2026; the entry stays as a historical reference and is not a choice for new users.
