Vercel has launched Eve, an open-source framework for building, running, and scaling AI agents. Released as the npm package eve under the Apache-2.0 license, the project is designed to simplify agent development by treating each agent as a directory of files, each mapped to specific capabilities.
By 2026, the landscape of AI agent development has matured significantly, with the industry moving toward modular, file-based architectures. Eve aligns with this trend by emphasizing simplicity: building an agent should mean defining what it does, not assembling the infrastructure required to run it in production.
The framework is already used internally at Vercel, where it powers over 100 agents in production. Eve automates many of the underlying complexities—such as tool registration, state management, and runtime orchestration—allowing developers to focus on agent logic rather than plumbing.
By structuring each agent as a directory with clearly defined files for capabilities, Eve provides both clarity and modularity. This design makes agents easier to develop, test, and deploy, while also enabling better composition and reuse across projects.
Eve is available now on GitHub and npm, inviting the developer community to build, customize, and scale their own AI agents without unnecessary overhead.
