Vercel has released Eve, an open-source framework for building, deploying, and operating AI agents in production. It uses a filesystem-first architecture where agent capabilities — instructions, tools, skills, subagents, channels, and scheduled tasks — are organized as files and auto-discovered at build time. Key production features include durable execution, sandboxed code execution, human approval workflows, subagent delegation, OpenTelemetry-based tracing, and built-in evaluation suites. Eve supports MCP and OpenAPI integrations with services like Slack, GitHub, and Snowflake, and can deploy agents across multiple communication channels. Vercel reports it already runs over 100 internal production agents using the framework. Eve enters a competitive space alongside LangGraph, CrewAI, AutoGen, and Strands, differentiating itself by bundling infrastructure concerns into a single cohesive framework.
