Open-source agent framework from Vercel — define agents as directories of TypeScript and Markdown config and deploy them as standard Vercel projects.
Treats agents as directories of config files rather than boilerplate-heavy systems. You declare the model, instructions, tools, skills, and deployment targets in TypeScript and Markdown — no production infrastructure to assemble. The framework Vercel builds and runs its own agents on.
Ships durable execution with checkpointing, isolated sandboxes for agent-generated code, human-in-the-loop approvals, MCP-based credential management, multi-channel deployment (Slack, Discord, Teams, GitHub), OpenTelemetry tracing, evals, and cron-scheduled tasks. Built on the open-source Workflow SDK; runs on Vercel Sandbox in production and Docker locally. Works with any Claude model or compatible provider via AI Gateway. Deploy with vercel deploy.
