SnapState is a universal checkpoint/resume API for AI agent workflows, now in public beta, supporting JS, Python, and MCP-compatible agents across any framework.
Key Takeaways
Cross-language resume is the core differentiator: a Python agent can resume a workflow checkpointed by a JavaScript agent, no shared runtime required.
Free tier covers 10k writes, 1 GB storage, 5k resumes, and 1k replays per month with no credit card required.
Native MCP server support gives Claude Desktop and Cline persistent workflow memory out of the box.
Agent identity tracking logs which agent executed each step, enabling handoffs between LangChain, CrewAI, AutoGen, and custom code without losing context.
Built-in analytics surface which steps fail most, which agents are fastest, and where workflows break across frameworks.
