Relay.app, founded in 2021, builds human approval steps into its core workflow logic rather than treating full autonomy as the goal: a workflow can pause at a specific point, sending a request to a person in Slack or email, and wait for approval before continuing, rather than executing every step automatically end to end.
That built-in pause point matters for AI-driven automation specifically, where a generated email, a financial action, or a customer-facing message might need a human glance before going out, and Relay treats that checkpoint as a standard workflow feature rather than something bolted on as an afterthought. A modern, clean interface reflects its more recent founding relative to older category incumbents.
A free tier covers limited monthly workflow runs, and paid plans start around $19 a month for more volume and advanced approval logic. For a team that wants AI-powered automation but isn't comfortable letting every action run fully autonomously, Relay's human-approval-first design addresses that specific hesitation more directly than platforms built around full autonomy as the default.
