Why Teams Switch

Why teams add GuardLayer when they outgrow LangSmith.

LangSmith solves a real dev problem. But once you ship AI to users, you need a different layer entirely.

Reason 01
LangSmith stops at the dev/prod boundary
Tracing prompts in a notebook is useful. Blocking a hallucinating response in production at 3am is different. GuardLayer operates where LangSmith observes — in the live request path, with guardrails that trigger before your users see the output.
Reason 02
You're not just using LangChain
LangSmith is optimized for LangChain workflows. If you're using OpenAI directly, Anthropic, or mixing frameworks, coverage gets patchy. GuardLayer sits at the API layer — framework-agnostic, model-agnostic, stack-agnostic.
Reason 03
No one wants to own AI ops full-time
With LangSmith, you see what's happening. You still have to respond, tune guardrails, and manage compliance. GuardLayer takes that operational work off your plate entirely. We run it — you ship features.
"LangSmith helped us build. GuardLayer helped us ship — and keep it running. We use both, but GuardLayer is what actually protects our users."
