LangSmith traces your agents. AgentShield traces, analyzes risk, enforces approvals, tracks costs, and generates compliance reports.
LangSmith is a developer debugging tool. AgentShield is an observability, governance, and compliance platform for AI agents in production.

LangSmith is a great debugging tool. But production AI agents need more than debugging.
LangSmith shows you what your agent did. It doesn't tell you if what it did was dangerous — hallucinations, unauthorized commitments, prompt injection, or compliance violations go undetected.
The EU AI Act deadline is August 2, 2026. LangSmith has zero compliance features — no risk classification, no regulatory reports, no audit documentation. Fines reach 7% of global turnover.
When your agent decides to process a $5,000 refund or send an email to a customer, LangSmith won't pause and ask for approval. AgentShield does — with configurable rules and a full audit trail.
LangSmith tracks costs at the project level with manual tagging. It has no per-agent budget limits, no automatic alerts at 80% spend, and no way to prevent a recursive loop from running up a $47,000 bill.
LangSmith charges per seat + per trace. AgentShield charges per event — no per-seat fees.
+ $0.50 per 1,000 traces
No per-seat fees
