The LangGraph-GUI Backend is an open-source FastAPI service that powers the LangGraph graphical interface. It handles CRUD operations on graph nodes and edges, manages workflow execution against various language models, and returns real-time inference results. The backend supports authentication, logging, and extensibility for custom plugins, enabling users to prototype, test, and deploy complex natural language processing workflows through a visual programming paradigm while maintaining full control over execution pipelines.

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.

Nexus Agents is a modular framework for constructing AI-driven multi-agent systems with large language models at their core. Developers can define custom agents, integrate external tools, and orchestrate workflows through declarative YAML or Python configurations. It supports dynamic task routing, memory management, and inter-agent communication, ensuring scalable and reliable automation. With built-in logging, error handling, and CLI support, Nexus Agents streamlines building complex pipelines spanning data retrieval, analysis, content generation, and customer interactions. Its architecture allows easy extension with custom tools or LLM providers, empowering teams to automate business processes, research tasks, and operational workflows in a consistent and maintainable manner.

Claude-Code-OpenAI transforms Anthropic’s Claude API into a drop-in replacement for OpenAI models in Python applications. After installing via pip and configuring your OPENAI_API_KEY and CLAUDE_API_KEY environment variables, you can use familiar methods like openai.ChatCompletion.create(), openai.Completion.create(), or openai.Embedding.create() with Claude model names (e.g., claude-2, claude-1.3). The library intercepts calls, routes them to the corresponding Claude endpoints, and normalizes responses to match OpenAI’s data structures. It supports real-time streaming, rich parameter mapping, error handling, and prompt templating. This allows teams to experiment with Claude and GPT models interchangeably without refactoring code, enabling rapid prototyping for chatbots, content generation, semantic search, and hybrid LLM workflows.
