About
Gain precision and control with LangGraph to build agents that reliably handle complex tasks. Build and scale agentic applications with LangGraph Platform.
LangGraph's flexible framework supports diverse control flows – single agent, multi-agent, hierarchical, sequential – and robustly handles realistic, complex scenarios. Ensure reliability with easy-to-add moderation and quality loops that prevent agents from veering off course. Use LangGraph Platform to templatize your cognitive architecture so that tools, prompts, and models are easily configurable with LangGraph Platform Assistants.
With built-in statefulness, LangGraph agents seamlessly collaborate with humans by writing drafts for review and awaiting approval before acting. Easily inspect the agent’s actions and "time-travel" to roll back and take a different action to correct course.

About
OpenHarness is an open-source TypeScript SDK for developers building custom AI-agent applications, including coding agents, CLI tools, and web-based assistants. It provides stateless agent execution, explicit conversation-state handling, streaming events, composable middleware for retries, persistence and context compaction, hierarchical subagents, and permission-controlled tools. Developers can connect model providers through the Vercel AI SDK, add external capabilities through Model Context Protocol (MCP), and use filesystem or shell tools through configurable providers. The SDK also offers React hooks and Vue composables for streaming agent output into application interfaces. OpenHarness is installed as an npm package and is intended to be embedded in projects running on Node.js or edge runtimes; it is a developer library rather than a hosted end-user agent service.
