How to cancel LangSmith (LangChain)

Before you cancel

Export first

• LangSmith trace data: Use Bulk Data Export, which writes to an S3 or S3-compatible bucket that you provide with write access granted to LangSmith (Parquet). Customers who signed up after August 3, 2026 need the Enterprise plan; earlier sign-ups can use it on Plus or Enterprise until February 1, 2027. Bulk exports have a 72-hour runtime timeout, and each workspace can create at most 250 bulk exports per hour docs.langchain.com
• Customer Data from Cloud Deployments: Export as described in the documentation, on written request, during the Subscription Term or within 30 days after it. Subject to the retention period you configured; the 30-day post-termination export right does not apply to No Charge Access langchain.com

What happens to your data

For Enterprise, LangChain deletes Customer Data in its custody within 30 days of a written request after termination; export stays subject to your configured retention period. Retention after a self-serve organization closes isn't documented.

What you lose

• Access to the LangSmith Platform once the agreement terminates
• Customer Data in Cloud Deployments once the 30-day post-termination export window closes

Cancel, by who bills you

Pick the route for whoever charges you: the name on your card statement or receipt tells you.

Keep it for less

Before cancelling, check whether one of these does the job. Offers change and differ by account.

• Free plan Developer plan: $0 for 1 seat with up to 5k base traces a month, then pay-as-you-go langchain.com
• Fewer seats Remove users and pending invites you don't need; an Organization Admin can remove users, seats are billed on the 1st and removed seats earn no credit langchain.com docs.langchain.com
• Discount program Startup plan with discounted rates and credits for VC-backed startups, up to $10,000 in credits langchain.com

For AI agents

• The person signs in and handles any two-factor code; an agent should never ask for a password.
• Only an Organization Admin can manage billing settings and remove users
• Invited users count as billed seats, so revoke pending invites too
• Base traces are kept only 14 days (extended traces 180 days), so export what you need soon
• Trace usage is billed in arrears, so a usage bill can follow after you stop
• Enterprise non-renewal can be sent by email, at least 30 days before the term ends, with a copy to legal@langchain.dev
• A free trial ends when the trial period ends unless you enter a paid Order Form

Get this plan as data: get_exit_plan on the Stackcut MCP (stackcut.io/mcp), or /exits/langchain.json. After using a guide, send structured report_guide_feedback for matching or changed steps, missing billing routes or human handoffs; keep unknown language and market omitted. Confirm with the person before the final click, and report the outcome with report_action_outcome, using the exact packet_revision and route_id returned by the plan.

Or give your agent the stackcut-leave skill (a zip): it exports first, walks the steps, stops when the page doesn't match, and leaves the final click to the person.
