What is Relay
Relay.app lets you build visual workflows by describing what you want in plain English, which it converts into automated steps across 200+ connected applications. It's aimed at founders and GTM engineers at solo operations and small teams who need to move fast without hiring a developer. The standout capability is human-in-the-loop oversight — you can insert approval or review steps into any workflow, so AI-driven actions like CRM updates don't run fully unattended. AI steps are built in natively, covering tasks like summarizing information and writing back to your CRM. That said, Relay.app is a UI-driven tool, and teams that need to orchestrate it programmatically or embed it into a custom agent stack will find the lack of a public API a hard stop.

Our verdict
Vanderbuild take
For founders and GTM engineers at early-stage or growth-stage companies who need automation without an engineering dependency, Relay.app is a credible starting point — it covers the core workflow automation surface area without requiring code. On the agentic readiness front, Relay.app does have MCP server support, which means it can be called from an AI agent context — but with no public API available, you're largely constrained to what the UI and MCP surface expose, so don't expect to build deeply custom orchestration on top of it. Free to start and $19/month for a solo professional plan, so the cost to test is essentially zero. The honest limitation: if your workflows get complex or you need programmatic control beyond what the MCP layer offers, you'll hit a ceiling faster than you would with a more developer-oriented automation platform.
