Agentspan
Durable execution for AI agents — crash-safe, human-in-the-loop, full observability.

Agentspan is an open-source Python server and SDK that compiles AI agent definitions into durable workflows backed by an industrial-grade orchestration engine. Agents survive process crashes, support human-in-the-loop approvals, and offer full observability across every tool call and LLM request. It integrates with popular frameworks like OpenAI Agents SDK, Google ADK, and LangGraph with minimal code changes.
Agent definitions are compiled into durable Conductor workflows hosted on a self-hostable server, so execution state persists outside the user's process and resumes automatically after crashes or worker reconnects.
