LangGraphJS API provides a programmatic interface to design AI agent workflows using directed graphs. Each node in the graph represents an LLM call, decision logic, or data transformation. Developers can chain nodes, handle branching logic, and manage asynchronous execution seamlessly. With TypeScript definitions and built-in integrations for popular LLM providers, it streamlines development of conversational agents, data extraction pipelines, and complex multi-step processes without boilerplate code.

Langroid provides a comprehensive agent framework that empowers developers to build sophisticated AI-driven applications with minimal overhead. It features a modular design allowing custom agent personas, stateful memory for context retention, and seamless integration with large language models (LLMs) such as OpenAI, Hugging Face, and private endpoints. Langroid’s toolkits enable agents to execute code, fetch data from databases, call external APIs, and process multimodal inputs like text, images, and audio. Its orchestration engine manages asynchronous workflows and tool invocations, while the plugin system facilitates extending agent capabilities. By abstracting complex LLM interactions and memory management, Langroid accelerates the development of chatbots, virtual assistants, and task automation solutions for diverse industry needs.
