SoloINC and LangGraph Platform
“Code-first stateful graphs”LangGraph Platform, on its own site, 2026-09-05.
A hosted platform for deploying and observing agents written as LangGraph graphs, paired with LangSmith for tracing.
| LangGraph Platform | SoloINC | |
|---|---|---|
| Hosting | Open-core framework; the platform and LangSmith are hosted, with self-hosted options at the enterprise tier. | A desktop app on a Mac you own (Apple silicon, macOS 26 or later), running on the model you bring: an AI subscription such as a Claude seat, a provider API key, or a local engine. No server of ours. Windows, iPhone, iPad and Android come later. |

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.
