What LangSmith does well

LangSmith provides deep tracing and evaluation capabilities for LangChain-based applications. It captures every step in complex LangChain chains, agents, and retrieval pipelines, making it invaluable for debugging and quality evaluation. Teams building sophisticated AI applications with LangChain find LangSmith's chain-level visibility extremely useful.

Observability vs. compliance

LangSmith shows you every data point that flowed through your LangChain application. That transparency is an asset for debugging — and a liability for compliance. Every unredacted Aadhaar number, PAN card, or salary figure that passed through your chains is now visible in LangSmith traces, documenting the compliance exposure.

CrewCheck sits upstream of LangSmith in the request path. Indian PII is redacted before it enters the chain, before it reaches any model provider, and before it appears in any trace. The audit trail shows the redacted payload, not the raw personal data.

Choose CrewCheck if…

DPDP compliance enforcement and Indian PII redaction are requirements

You need compliance evidence, not just observability traces

You use providers beyond LangChain's default integrations

Choose LangSmith if…

You are deeply invested in LangChain and need chain-level debugging

Prompt evaluation and dataset management are your primary needs

Compliance is handled by a separate layer in your architecture
