Should you use it?
LangGraph is LangChain's low-level runtime for long-running, stateful agents and workflows. The library is MIT-licensed and free for Python and JavaScript/TypeScript teams; LangSmith adds paid observability and deployment, with Developer at $0/seat/month, Plus at $39/seat/month, Enterprise custom, and LCU/LSU usage meters as of July 30, 2026. Pick it when you need durable execution, persistence, streaming, or human approval. Skip it for simple one-shot calls or no-code automation.

Full review notesLong-form details, FAQ, and source history
LangGraph is LangChain’s low-level orchestration runtime for stateful AI agents. Where LangChain gives you higher-level agent APIs, LangGraph gives developers explicit control over graphs, state, persistence, interrupts, streaming, and multi-agent workflows.
System Verdict
Pick LangGraph if you are building production agents that need more than one LLM call. It is strongest when the workflow must branch, loop, pause for approval, persist state, recover after failure, or coordinate multiple agents.
Skip it if the job is a simple prompt, tool call, or no-code workflow. Direct provider SDKs, LangChain’s higher-level agent API, Mastra, CrewAI, or LangFlow can be faster depending on the team and abstraction level.
Commercial reality: the LangGraph library is free and MIT-licensed. The paid layer is LangSmith: Developer is $0/seat/month with 5k base traces, Plus is $39/seat/month with 10k base traces and one free small serverless deployment, Enterprise is custom, and Deployment, Fleet, Engine, Sandboxes, traces, and storage use LCU/LSU or trace-based meters.

When to pick LangGraph
- Long-running stateful agents. Research pipelines, support workflows, code agents, and process automations that need to remember state and resume cleanly fit LangGraph’s design.
- Durable execution matters. LangGraph is built for workflows that can recover from failures and keep running over time, not just one request-response loop.
- Human-in-the-loop workflows. Interrupts let a team inspect, edit, approve, or reject state before the agent continues.
- Multi-agent or subgraph systems. Subgraphs help split complex agent behavior into smaller units without giving up central state control.
- LangSmith is already part of the stack. The first-party tracing, evals, Studio, and Deployment path are smoother when the team is comfortable with LangChain’s ecosystem.
When to pick something else
- Simple one-shot LLM calls: direct OpenAI, Anthropic, or Google SDKs.
- TypeScript-first agents with product-style ergonomics: Mastra is purpose-built for TypeScript teams.
- Visual no-code or low-code building: LangFlow gives a canvas for LangChain and LangGraph workflows.
- Role-based multi-agent prototypes: CrewAI is easier when the mental model is “crew of specialist agents” rather than explicit graph state.
- Azure-aligned enterprise: Microsoft Agent Framework is the more natural fit when Azure AI Foundry is the default platform.
What changed recently
- July 30 source recheck: LangGraph’s current docs still position it as the low-level orchestration runtime for durable execution, streaming, human-in-the-loop control, memory, and persistence, with LangSmith as the tracing/evaluation/prompt/deployment platform.
- LangSmith deployment pricing changed. The public pricing page now shows Deployment, Fleet, Engine, and Sandboxes metered in LCUs/LSUs, with one free small serverless deployment on Plus. The older per-run and uptime numbers should no longer be used as current pricing.
- Trace pricing is now framed as base charges plus extended-retention upgrades. Usage docs state .05 cents per base trace and .50 cents total for extended-retention traces. They also state 400-day default extended retention, while the pricing FAQ still contains a conflicting 180-day sentence.
- Deployment scope widened in the docs. LangSmith Deployment is now framed as framework-agnostic agent infrastructure: LangGraph/LangChain are first-party paths, while Deep Agents, Google ADK, and other frameworks can also route through the same Agent Server runtime.
- Fleet and infrastructure meters matter. Fleet, Engine, Deployment, and Sandboxes now use LCU and LSU meters, so production costs depend on compute, memory, storage, and agent workload behavior.
Pricing
| Product | Current public price | Notes |
|---|---|---|
| LangGraph library | $0 | MIT-licensed open-source framework |
| LangSmith Developer | $0/seat/month | One seat plus 5k included base traces per month |
| LangSmith Plus | $39/seat/month | 10k included base traces, one free small serverless deployment, access to Deployment, Engine, and more |
| LangSmith traces (base) | .05 cents per trace | 14-day retention, equivalent to $0.50 per 1k traces after included allowance |
| LangSmith traces (extended) | .50 cents total per trace | Usage docs say extended retention is 400 days by default; pricing FAQ still says 180 days, so treat the docs as the safer operational source and verify before committing high-retention spend |
| LangSmith Deployment | LCU/LSU metered | Plus includes one free Serverless Small deployment; additional Serverless and Dedicated deployments are charged by resource consumption |
| Fleet, Engine, and Sandboxes | LCU/LSU metered | Fleet and Engine consume LCUs; Sandboxes consume LCU compute/memory and LSU storage |
| LCU / LSU units | $1.50 per LCU / $1.00 per LSU | Public calculator defines LCUs for compute/work and LSUs for traces/storage |
| LangSmith Enterprise | Custom | Adds alternative hosting, custom SSO/RBAC, and dedicated support |
Pricing verified July 30, 2026 against LangChain’s public pricing, LangSmith billing docs, and LangSmith usage-and-billing docs. Model/API provider costs are separate from LangSmith.
Failure Modes
- Low-level by design. LangGraph does not hide the agent architecture. Teams must still design state, tools, routing, evals, and deployment behavior.
- Billing has multiple meters. Seats, base traces, extended-retention upgrades, Deployment LCUs/LSUs, Fleet LCUs, Engine LCUs, Sandbox compute/storage, and third-party model costs can all matter once LangSmith is in production.
- Resource meters replaced the old uptime shorthand. Do not estimate current Deployment spend from the old per-run or per-minute numbers. Use LangChain’s public calculator and resource rates, then tear down unused deployments and sandboxes.
- Model spend is separate. LangSmith can price seats, traces, deployments, Fleet, Engine, and sandbox compute, but OpenAI, Anthropic, Google, Mistral, or local-infrastructure model costs still sit outside the LangSmith bill.
- Verbose for simple work. call or straightforward tool call is usually cleaner with a direct SDK.
- LangChain conventions still show up. LangGraph can be used standalone, but many real projects use LangChain message, tool, and model abstractions around it.
- Python examples are the deepest path. JavaScript/TypeScript support is real, but Python remains the more mature documentation and community path.

Methodology
Produced by the aipedia.wiki editorial pipeline. Last verified July 30, 2026 against LangGraph official materials, LangGraph Python and JavaScript docs, LangChain pricing, LangSmith billing docs, LangSmith usage-and-billing docs, LangSmith Deployment docs, the LangGraph GitHub repository, and the LangChain/LangGraph v1.0 announcement.
FAQ
Is LangGraph really free? Yes. The LangGraph library is MIT-licensed and free to use. Paid spend starts when a team uses LangSmith services such as observability, evaluation, or hosted deployment.
What replaced LangGraph Platform? LangChain’s current public product language calls the hosted layer LangSmith Deployment. LangSmith billing docs describe it as the deployment product formerly called LangGraph Platform.
Do I need LangChain to use LangGraph? No. LangGraph can be used standalone, but the docs commonly use LangChain components for models and tools, and many teams pair it with LangSmith for tracing and evals.
What’s the difference between LangGraph and LangChain? LangChain is the higher-level agent framework. LangGraph is the orchestration runtime underneath or beside it when you need durable execution, persistence, human-in-the-loop, streaming, and explicit state control.
Does LangGraph compete with Mastra? Yes, especially for TypeScript teams choosing an agent/workflow framework. LangGraph has the broader LangChain/LangSmith ecosystem; Mastra often feels more native for TypeScript-first product engineering.
