Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 139 of the 178 other AI agents we grade
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.
To get you started, here are 9 things to know about LangGraph, taken from its own pages and our grades.
You write code and run it yourself, or deploy an Agent Server.
- 1
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.
- 2
Paid plans start at $39 a month for each person
As its pricing page puts it: $39 per seat / month, billed monthly.
- 3
There is a free plan
The LangGraph library is MIT-licensed and free. LangSmith Developer is $0 for 1 seat with 5k base traces a month.
- 4
It runs on Web
Web.
- 5
Graph-based agent control
Low-level primitives for single-agent, multi-agent and hierarchical control flows in one framework.
- 6
Human-in-the-loop
Approval and moderation checks can be added so a person can steer or approve agent actions.
- 7
Persistent memory
Built-in memory stores conversation history and keeps context across sessions.
- 8
A 2.6 GPA, above 139 of 178
That is against the other AI agents we grade, on value, the free plan, features, ease of use and platforms.
- 9
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.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | The 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. |
| Free plan and trial | A | Free outright: the MIT library has no cap, and LangSmith Developer is $0 for one seat with 5k traces a month. |
| Features | B | Single and multi-agent control, human approval, persistent memory, streaming and an Agent Server for deployment. The framework has no visual builder. |
| Ease of use | D | You write code and run it yourself, or deploy an Agent Server. We found no store rating. |
| Platforms and integrations | B | A code library with LangChain, LangSmith and MCP connections, plus hosted, hybrid or self-hosted deployment. No desktop or phone app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- Developers who want fine-grained control over agent logic
- Teams already using LangChain and LangSmith for tracing and evals
- Agents that need approvals, long-running state or memory
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.

Part 04 · Standing
Where it stands
Its grades against its category, and whether to keep it or make your own
139/178
Other AI agents it is graded above
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.
Each grade against the category
Every bar is all 179 AI agents we grade, cut by the letter each got. LangGraph’s own letter is outlined.
- CValue for moneyAbove 28 of 178

Price against what you get
Each dot is one of 109 AI agents. Further left costs less; higher up scores better on features, ease of use and platforms. LangGraph is the marked dot.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
