PromenautHow we compare / LangGraph
Promenaut vs LangChain and LangGraph
LangGraph is a strong choice for engineers who want low-level control of an agent’s logic.
Promenaut ships the workforce those tools leave you to build: modules of agents, teams and workflows, with approval, budgets and run evidence around them.

Where rivals win
Each comparison says where the other tool is stronger.
| What a regulated firm asks | Promenaut | LangGraph |
|---|---|---|
| What it is | A governed workforce: modules of agents, teams and workflows | An open-source agent framework and low-level orchestration runtimeSource ↗ |
| Where it runs | In your own cloud account from a shipped kit, including one with no outbound access | The library runs anywhere; LangSmith in their cloud, hybrid or self-hostedSource ↗ |
| Choice of model | Anthropic, OpenAI and Google directly, Amazon Bedrock, or your own AI gateway | Any model provider, through a standard interfaceSource ↗ |
| Who builds the work | Shipped as modules of agents, teams and workflows, extended with the SDK | You build the agents and the graphsSource ↗ |
| A person decides | Work held for a person’s decision, approved or rejected with its history kept | Interrupts pause a run and wait for a personSource ↗ |
| How cost works | Credits by each agent’s tier, estimated before launch | A free library; LangSmith per seat and usage, cost tracked per traceSource ↗ |
| Governance around it | Deputy access to knowledge, budgets per business unit, and a verdict from each run | LangSmith tracing of each step, with evaluationsSource ↗ |
