Four vendors in four categories shipped plain-language agent builders on September 25.

n8n Agents in automation, Warp's agent routines in HR, Kantata Agent Studio in professional services, Shield's Build with Forge in managed IT. Each replaces a drag-and-drop canvas or logic tree with written instructions the product compiles into a running agent. Warp's CEO describes the input as an internal company document you "upload and tweak in plain English." n8n's framing is sharper: sometimes you want "the agent in charge, with workflows as tools." Microsoft's Autopilot, launched the same day, is the same shape at suite scale. The workflow builder is becoming something the agent calls rather than the product the customer buys, which is bad news for every vendor whose moat was the canvas.
