Key differences

Chat-based vs code-based building

nanogent.ai

Describe your agent in plain language. No Python, no graph definitions, no node configurations. Ship a production agent in minutes.

LangGraph

Define agents as graphs in Python or JavaScript: nodes represent steps, edges represent transitions. Maximum control for developers, but requires programming expertise and a steep learning curve.

Time to production

nanogent.ai

Most teams deploy their first agent in under 15 minutes. Non-technical team members can build, test, and iterate without developer involvement.

LangGraph

Production-ready agents typically take days to weeks. You need to define the graph structure, configure state management, set up hosting infrastructure, and handle deployment yourself (or use LangGraph Platform).

Total cost of ownership

nanogent.ai

Flat-rate monthly pricing includes hosting, deployment, and all infrastructure. BYOK support for AI cost control. No hidden fees.

LangGraph

The framework is free, but production costs add up: LLM API fees, LangGraph Platform hosting ($0.001/node execution), LangSmith observability ($39/seat/month), plus your own developer time for maintenance.

Target audience

nanogent.ai

Built for solopreneurs and small businesses. No code, no infrastructure, no DevOps. Your marketing team can build and maintain AI agents.

LangGraph

Built for developer teams at companies like Uber, LinkedIn, and Klarna. Ideal when you need fine-grained control over agent behaviour and have engineers to build and maintain the system.
