agent-framework typescript durable-workflows vercel open-source

Vercel ships eve open-source agent framework

Eve treats agents as directories, compiles them to durable workflows with automatic tool registration via filename convention—no separate registration needed.

June 23, 2026

Summary

Eliminates boilerplate for agent scaffolding (model config, prompts, tools, observability) and bakes in crash recovery via checkpointed workflows. Reduces agent deployment friction to a single `vercel deploy` command, matching web app workflows.

Why it matters

Implementation verdict

Replaces manual workflow orchestration and tool registration patterns in LangChain/LangGraph setups. Requires Vercel hosting (cross-platform support "coming"); worth trying now for TypeScript teams already on Vercel, but lock-in risk is real. Public preview means API breakage possible.
