LangSmith

LangChain

Commercial

Framework-agnostic platform from LangChain for tracing, monitoring, evaluating and deploying LLM apps and agents, with OpenTelemetry ingest.

Curated by Tiberiu ArvaVerified

Proprietary

Strengths

  • Works beyond LangChain (OpenAI, CrewAI, Vercel AI)
  • Cloud in US, EU, APAC and AWS regions
  • Self-hosted and hybrid options on Enterprise

Practitioner note

The lowest-friction option for LangChain and LangGraph shops, but it also ingests OpenTelemetry from other stacks. Base traces keep only 14 days (extended traces 180), and audit logs, self-hosting and hybrid all need the Enterprise plan.

EU AI Act obligations

Risk tier: Not applicable · as of 2026-08-23

Source-backed information mapped from LangSmith's tracked risk tier — not legal advice. Obligations depend on how your organisation deploys the system; see the full obligation reference and timeline.

This record's EU AI Act risk tier is marked not applicable, so no tier-specific obligations attach. Deployers embedding it in an AI system in scope of the Act should assess that system's own tier.
