Durable, stateful graphs with checkpoints and streaming are hard to get right, and LangGraph gets them right. LangSmith's tracing is mature. Developers who think in graphs will feel at home.
A graph, not a company. Observability is the upsell there; in SoloINC the traces, the audit log and the run records are in the free core, on your machine.
Your product is the graph, you want a managed deployment for it, and tracing as a paid service is acceptable.
