Agentspan is an open-source server and SDK for running AI agents as durable workflows. You can define agents programmatically, execute them server-side, and inspect each run and execution state in the UI. Agentspan adds crash recovery, human-in-the-loop approvals, guardrails, tool history, and observability around the agent frameworks and LLMs you already use. MIT licensed.
Hey Product Hunt,
We built Agentspan because production agent execution gets messy fast, and we're working to fix that. Common issues include state loss, human approvals needing resume logic, tool calls needing auditing, and retries causing repeated side effects.
Agentspan gives agents a durable execution layer. You define agents client-side, but execution state, tool history, approvals, and observability live on the server. The goal is to make agents easier to operate and debug without forcing teams to abandon the frameworks or models they already use.
The project is open source and MIT-licensed. Check out the repo at https://github.com/agentspan and the quickstart at https://agentspan.ai/docs/quicks....
