A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

	LangGraph Agents	Open WebUI Agents
Tagline	Stateful, graph-based agent orchestration from LangChain.	Self-hosted, extensible AI chat platform that runs on your infrastructure
Category	Agents	Agents
Pricing	Freemium· Developer: $0 / seat per month · Plus: $39 / seat per month · Enterprise: Custom pricing	Freemium· Free (self-hosted, MIT-style community license via pip/Docker) / Enterprise: custom pricing for SSO, RBAC, audit logs, air-gapped deployment, data-residency guarantees
Model	BYO (Claude / GPT / open)	Backend-agnostic: any Ollama, llama.cpp, vLLM, or OpenAI-compatible API (OpenAI GPT, Anthropic Claude, Llama 3.x, Qwen, Mistral, Gemma, etc.)
Editorial score	8.8 / 10	—
Use cases	stateful agentshuman-in-loopproduction	Self-hosted ChatGPT alternative for a teamPrivate RAG chatbot over internal documentsUnified gateway across multiple LLM providersAir-gapped LLM chat for regulated industriesOllama front end for local Llama or Qwen modelsCustom Python tools and function callingPrompt library and workspace sharingVoice and vision chat on local modelsModel access control and usage auditingHome-lab AI assistant on a single GPU box
Pros	Reliable, debuggable agent graphs Built-in persistence + HITL Production-grade Tight LangSmith integration	Genuinely self-hostable in minutes with Docker or pip; no account or callback required Backend-agnostic: talks to Ollama, llama.cpp, vLLM, OpenAI, Anthropic, Groq, OpenRouter and any OpenAI-compatible API through one UI Built-in RAG over uploaded docs, web search, image generation, voice, and function calling Python pipelines and tools framework lets you extend the app without forking it Multi-user with roles, workspaces, model access controls, and audit-friendly logs Very active community with a marketplace of shared prompts, models, tools, and functions Enterprise tier adds SSO, RBAC, and air-gapped deployment for regulated environments
Cons	Steeper learning curve than CrewAI Verbose to set up	You are responsible for hosting, updates, GPU/model provisioning, and backups Feature velocity is high, so breaking changes and rough edges appear between releases RAG and evaluation features are competent but not as deep as purpose-built tools like LangChain, LlamaIndex, or Ragas Enterprise pricing is not published and requires a sales conversation Multi-tenant performance depends entirely on the model backend you wire in; the UI cannot fix a slow local model
