# Agentspan

An open-source server and SDK that compiles Python agent definitions into durable, crash-resilient workflows with built-in human-in-the-loop approval.

**Route:** surfaced by the AI Development and Deployment Infrastructure lane's de-branded queries → competitor to vercel.com.

**Why it's on the map:** Sells the same durable-agent-execution capability to the same AI/agent developers who might choose the anchor Vercel's AI SDK for building production agentic workloads.

**Receipts** (verbatim from its page this run):

> An open source server and SDK. Your agent definitions compile into durable workflows

> Your process dies. The agent doesn't.

> Mark any tool as requiring approval. The agent pauses, holds state on the server with no timeout, and waits.
