The framework for
building agents
Like Next.js for web apps, but for agents. Markdown for instructions and skills, TypeScript for tools. Durable by default.
An agent is a directory
Define instructions and skills in markdown, tools in TypeScript, and deploy. The framework compiles the directory, wires up durable workflows, and connects channels.
Leverages all Vercel AI primitives
AI Gateway for model calls, Sandboxes, Workflows, and Connect. All critical agent infrastructure works out of the box, no gluing point solutions together.
Everything you need for production agents
Enterprise governance, observability, and sandboxed compute come standard. Focus on building, not infrastructure.
Durable executionWorkflows survive crashes and restarts. Every step is checkpointed. Agents park when waiting, resume on the next message.
Sandboxed computeAgents spin up isolated VMs on demand. File system access, bash execution, and code runs, all completely isolated.
Multi-channel deliveryOne agent codebase deploys to web chat, Slack, API, cron, CLI, and custom apps.
Human-in-the-loopTools that need confirmation trigger approval gates. Sessions park until resolved, then resume seamlessly.
SubagentsDelegate specialized work to child agents with their own prompts, tools, and sandbox.
EvaluationsDefine test suites with scoring rubrics. Run evals on every deployment and on a schedule.
