Which plan is right for me?

Developer suits personal projects with 1 free seat and 5k base traces / mo. Plus is for teams that want self-serve with unlimited seats, 10k base traces / mo, and 1 free small serverless deployment. Enterprise is for advanced administration, security, support, or deployment needs; contact sales.

Do you offer a plan for startups?

Yes. LangSmith for Startups offers discounted rates and credits for VC-backed startups, with up to $10,000 in credits.

When will I be billed?

For Developer or Plus, seats are billed monthly on the 1st or pro-rated if added mid-month with no credit for removed seats; traces are billed monthly in arrears. Enterprise plans are invoiced annually upfront.

A seat is a distinct user inside your organization. The total number of users, including invited users, is used to determine the number of seats to bill.

Can I upgrade from Developer to Plus or Enterprise?

Yes. Developer plan users can upgrade to Plus on the Plans and Billing page. For Enterprise, contact the sales team.

An LCU (LangChain Compute Unit) is a normalized unit of work done on the LangSmith Platform used for pricing. Different services meter at different rates. 1 LCU = $1.50. Examples include Engine, Fleet, deployments, and sandboxes.

An LSU (LangChain Storage Unit) is a normalized unit of data stored or managed by LangSmith used for pricing. 1 LSU = $1.00. Examples include traces, deployments, and sandboxes.

What is the difference between a base trace and an extended trace?

Base traces have a 14-day retention period. Extended traces have a 400-day retention period and can be upgraded from base traces for an additional fee.

Are Tuned Evaluations charged for every agent run?

Tuned Evaluators are billed only when a Tuned Evaluator runs successfully. Skipped and failed evaluations are not billed. They are currently in public beta for Plus and Cloud Enterprise plans in the US.

Does LangSmith Deployment include any free deployments?

Plus plans include 1 free small serverless deployment. Additional serverless or dedicated deployments are charged on usage (resource time).

Serverless vs. dedicated deployment?

Serverless deployments scale to zero when idle and are intended for testing, background, or internal agents. Dedicated deployments are always on and intended for production workloads that require autoscaling, backups, and high availability.

Are Fleet model costs included in Fleet pricing?

Yes. Fleet pricing includes underlying model costs across Fast, Pro, and Max tiers.

How is Fleet metered?

Fleet usage is measured in LCUs. Developer includes 5 LCUs per organization each month; Plus includes 25 LCUs per organization each month. After the allowance, Developer pauses new runs until reset or upgrade; Plus bills additional usage.

How is Engine priced and when does it run?

Engine is metered in LCUs at $1.50 / LCU. An Engine run can consume ~5–30 LCUs. Engine is scheduled to run once every 6 hours. Pricing includes underlying model usage.

How is Sandbox uptime calculated?

Sandboxes are billed per second as ephemeral compute environments with configurable TTLs; inactive sandboxes shut down automatically. Sandboxes are available for SaaS Cloud deployments and not currently available for self-hosted deployments.

Quick pricing verdict

Starting price: $0 / seat per month on the Developer plan, then pay-as-you-go.
Free plan: Yes. Developer is $0 / seat per month, includes up to 5k base traces / mo, and is limited to 1 seat.
Best plan for most people: Plus at $39 / seat per month. It adds 10k base traces / mo, unlimited seats, 1 free small serverless deployment, Engine, and 25 LCU of Fleet usage / mo.
Plan to avoid first: Enterprise. Pricing is custom and built for advanced hosting, security, and support needs you probably do not need early on.
Biggest hidden cost: Pay-as-you-go charges beyond the included base traces, plus LCU and LSU metering for Deployment, Fleet, Engine, and Sandboxes once included allowances are used.
Pricing checked: 2026-08-21, against the official page

LangGraph is sold as part of the LangSmith platform under three plans: Developer ($0 / seat per month), Plus ($39 / seat per month), and Enterprise (custom pricing). Every plan charges pay-as-you-go on top of the seat fee.

All usage is metered in two units. An LCU (LangChain Compute Unit) covers work and compute at $1.50 / LCU. An LSU (LangChain Storage Unit) covers traces and storage at $1.00 / LSU. Specific products like Deployment, Fleet, Engine, and Sandboxes meter at their own per-resource rates.
