Vercel, the company behind Next.js, is bringing its signature developer experience to AI agents with a new open-source framework called Eve. Think of it as Next.js for agents: a file-driven architecture that automates the messy business of stitching together pipelines. Drop an agent.ts (model config), instructions.md (system prompt), and a tools/ directory into a folder, and Eve handles the rest — from development straight to production.
Under the hood, Eve builds on an open-source Workflow SDK to deliver "durable execution," meaning the framework checkpoints every step of a session. If your service crashes or gets redeployed, the agent picks up right where it left off. Security? Agent code runs inside Vercel's isolated Sandbox, and high-risk operations can require human-in-the-loop approval. Eve also plugs into the Model Context Protocol (MCP) via declaration files, letting agents tap into external tools and data sources.
Vercel is already dogfooding this hard — over 100 Eve-built agents are running in production internally. The most active, a data analysis agent called d0, handles more than 30,000 queries per month inside Slack. Developers can jump in today with `npx eve@latest init
` to scaffold a project and debug it visually through a terminal UI.
