Open Source Agent Framework, eve, Released

Vercel has released eve, an open source framework for building, running, and scaling agents. eve defines agents as a simple file directory structure, providing production-ready features by default.

Key features include:

• Durable execution
• Sandboxed compute
• Human-in-the-loop approvals
• Subagents
• Evals

Users can manage model settings, instructions, tools, skills, channels, and schedules as individual files. When adding new tools or skills, there's no need to write separate registration boilerplate code—simply adding the file automatically wires it up at build time.

With the npx eve@latest init command, you can set up a local development environment in under a minute, and the generated project can be deployed straight to production via vercel deploy, just like a typical Vercel project. eve is currently available as open source.
