Best for building controllable AI agents in code
LangGraph is an MIT-licensed library for agent control flow, with human approval steps, memory and streaming. It is code only, and hosting on LangChain's servers needs LangSmith Plus at $39 a seat a month, with usage billed on top.
Who LangGraph is for
- Fits if you write Python or JavaScript and want control over each agent step
- Works for teams that already use LangChain or LangSmith
Who LangGraph is not for
- Not for you if you want a visual builder, because the framework itself has none
- Pricey if you deploy on LangChain's servers, which needs Plus at $39 a seat a month
- Watch out: traces, Agent Server compute and sandboxes are metered in LSUs at $1 each past the allowances
- Tight if you need history, since base traces are kept 14 days and 180-day traces cost extra
Why LangGraph gets a 2.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyThe library is free, but deploying on LangChain's infrastructure needs LangSmith Plus at $39 a seat, above the category's middle of $25, with usage billed in LSUs.
- AFree plan and trialFree outright: the MIT library has no cap, and LangSmith Developer is $0 for one seat with 5k traces a month.
- BFeaturesSingle and multi-agent control, human approval, persistent memory, streaming and an Agent Server for deployment. The framework has no visual builder.
- DEase of useYou write code and run it yourself, or deploy an Agent Server. We found no store rating.
- BPlatforms and integrationsA code library with LangChain, LangSmith and MCP connections, plus hosted, hybrid or self-hosted deployment. No desktop or phone app.

LangGraph's GPA of 2.6 is higher than 139 of the 178 other AI agents we grade, and level with 20.
It stands best on free plan and trial (A, above 167 of 178) and worst on ease of use (D, above 0).
Its paid plans start at $39 a month for each person, against a middle price of $25 for the category: 65 of the 98 others that charge start lower.
On features, ease of use and platforms it scores 2.3 out of 4. 29 tools score higher and cost less.

Keep LangGraph, or make your own?
Keep it
To replace LangGraph you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
It is one of the better ones too: its GPA of 2.6 is higher than 139 of the 178 other AI agents we grade. It costs $468 a year. LangGraph is open source, so there is a third way: take its code and run it yourself.
What you could not
- An AI agent, with the models and the safeguards behind it.
- Connections to other products, each kept working as those products change.
- It is priced for each person, which means accounts and billing for a team.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. LangGraph’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is LangGraph?
LangGraph is a low-level orchestration library from LangChain for building agents as stateful graphs, with human-in-the-loop checks, persistent memory and token-by-token streaming. The library is MIT-licensed and free. Hosting the agents you build is sold separately through LangSmith's Agent Server, which needs a Plus or Enterprise plan.
Worth knowing
- The library is code only; there is no visual builder in the framework itself.
- Deploying on LangChain's infrastructure needs LangSmith Plus ($39 per seat / month) or Enterprise; the Developer plan has no Agent Server.
- Beyond the included allowances, traces, Agent Server compute and sandboxes are metered in LangSmith units (1 LSU = $1).
- Base traces are kept 14 days; 180-day extended traces cost extra.
Key features
- Graph-based agent control
- Low-level primitives for single-agent, multi-agent and hierarchical control flows in one framework.
- Human-in-the-loop
- Approval and moderation checks can be added so a person can steer or approve agent actions.
- Persistent memory
- Built-in memory stores conversation history and keeps context across sessions.
- Streaming
- Native token-by-token streaming exposes the agent's reasoning and actions as they happen.
- Agent Server deployment
- LangSmith Agent Server hosts agents in the cloud, in a hybrid setup, or fully self-hosted, with cron scheduling, an Assistants API and Studio.
