The enterprise platform for the full agent development lifecycle
Most enterprise AI initiatives stall before reaching customers. LangChain provides a single platform to build, evaluate, deploy, monitor, and iterate on your agents.








Three ways to build,
from full harness to full control
Each package solves a different problem. Choose whereyou want to start, then compose the rest ofthestack around it.
Own your AI stack
Build agents with the models, infrastructure, and tools that fit your business, while keeping control over the intelligence layer that differentiates your products and services.
Standardize agent development
Align teams around a shared development lifecycle so they can reuse best practices, cut duplicated work, and collaborate with subject matter experts.
Move faster from pilot to production
Turn promising AI experiments into production agents faster, with built-in support for evaluation, deployment, and continuous improvement.
Scale AI responsibly
Grow agent adoption while supporting security and compliance programs with built-in role-based access control, audit trail, and sensitive data protection.

One platform for the entire agent lifecycle
Iterate
Use production signals for root-cause analysis and continuous agent improvement.
Test
Validate behavior before deployment with traces, datasets, and evaluations that make quality measurable and repeatable.
Deploy
Run agents on secure infrastructure built for long-running tasks, persistent state, and reliability.
Govern
Set policies for sensitive data, retention, auditability, and model usage across your AI applications.
Monitor
Track quality, cost, latency, and reliability with dashboards, alerts, and online evaluations.
Build
Standardize how teams build agents, with the flexibility to choose the right models, architecture, and level of abstraction for each use case.
Govern data and LLM spend
Sensitive Data Management
Limit access to PII in-platform with ABAC, and redact sensitive data before it's sent to model providers.
Data Retention
Configure custom data retention policies at the project or workspace level to meet data privacy requirements.
Audit Trail
Stay prepared for security and compliance reviews by maintaining an immutable record of every user action.
Cost Controls
Monitor and set limits on evaluator and model spend, so teams can manage costs centrally.
Compliance and controls for enterprise teams

Common questions from security and teams
No. LangChain commits that it will not train on your data, and you own all rights to it. Retention windows are configurable and PII masking can hide sensitive fields before they reach LangSmith servers.
LangSmith is SOC 2 Type 2 and ISO 27001 certified, GDPR compliant, and HIPAA compliant. Audit reports, penetration test summaries, and a pre-signed DPA are available through the Trust Center (trust.langchain.com).
No. LangSmith is framework-agnostic and built on open standards, so your AI strategy is never tied to a single stack. You can trace langgraph, langchain, or deepagents, or integrate any stack via the Python, TypeScript, Go, and Java SDKs or OpenTelemetry. This enables users to swap models or frameworks without losing your observability, evaluations, or history.
Enterprise plans are tailored to your deployment model, trace volume, and support needs, with volume commitments, admin-level cost controls, and priority support with accelerated response-time SLAs. Talk to sales for a quote.
