Have a question about our plans?
If you’ve signed up for LangSmith before April 2nd, you have a grace period until mid-May at which point pricing will be enforced. At that point if you want to add seats or use more than the monthly allotment of free traces, you will need to put a credit card down or contact sales. If you are interested in the enterprise plan with special deployment options, reach out to sales@langchain.dev.
If you’re an individual developer, the Developer plan is a great choice for small projects. For teams that want to self-serve LangSmith, check out the Plus plan. If you need more advanced administration, authentication and authorization, deployment options, support, or annual invoicing, the Enterprise plan is right for you.
Seats are named to a specific developer. All accepted invitations in an account will be counted as a seat.
A trace is one complete invocation of your application chain or agent, evaluator run, or playground run. Traces can include many calls to an LLM or other tracked events. We don't want to penalize you for complexity, so go ahead and design the chain or agent capable of accomplishing sophisticated tasks. Here is an example of a single trace.
If you’ve consumed the monthly allotment of free traces in your account, you can purchase credits via credit card on the Developer and Plus plans to continue sending traces to LangSmith. If you’ve hit the performance usage limits on your tier, you can upgrade to a higher plan to get better limits, or reach out to support@langchain.dev with questions.
Yes, we offer ACH payment on the Enterprise plan, and we’re happy to work with your procurement team to onboard as a new vendor.
Seats are billed monthly on the first of the month or pro-rated if additional seats are purchased in the middle of the month. Churned seats mid month won’t get credited. You can purchase LangSmith credits for your tracing usage. As long as you have credits in your account, we’ll service your traces and deduct from your credit balance. You’ll be able to set alerts and auto-top ups on credits if you choose.
Enterprise plan customers are billed annually by invoice.
On the Plus plan, you receive preferential, email support at support@langchain.dev. On the Enterprise plan, you’ll get white-glove support with a Slack channel, a dedicated customer success engineer, and monthly check-ins to go over LangSmith and LangChain questions. We can help with anything from debugging, agent and RAG techniques, evaluation approaches, and cognitive architecture reviews. If you purchase the add-on to run LangSmith in your environment, we’ll also support deployments and new releases with our infra engineering team on-call.
When using LangSmith hosted at smith.langchain.com, data is stored in GCP us-central-1. If you’re on the Enterprise plan, we can deliver LangSmith to run on your kubernetes cluster in AWS, GCP, or Azure so that data never leaves your environment. For more information, check out our documentation.
We have our SOC 2 Type I certification, and we are in our SOC 2 Type 2 observation period. We expect to receive our SOC 2 Type 2 certification in July, and we will update this page accordingly. You can request more information about our security policies and posture at trust.langchain.com.
We will not train on your data, and you own all rights to your data. See LangSmith Terms of Service for more information.
