Honest comparisons for regulated AI
Tracing is necessary. Regulated workflows require audit-grade evidence: policy checkpoints, human decisions, sampling outcomes, and verifiable exports.

KLA vs LangSmith
LangSmith is excellent for tracing, evals, and annotation workflows. KLA is built for regulated workflows: decision-time policy gates, approval queues, and auditor-ready evidence exports.
KLA vs Traceloop (OpenLLMetry)
Traceloop/OpenLLMetry is excellent for OpenTelemetry-first tracing. KLA adds governance controls and verifiable evidence exports for audits.
Gateways & guardrails
I need a gateway / guardrails layer
Provider abstraction, routing, request controls, and middleware guardrails.
KLA vs Helicone
Helicone is a strong gateway + observability layer across providers. KLA governs workflow decisions with approvals and exports auditor-ready evidence packs.
KLA vs LiteLLM
LiteLLM is a strong model proxy/gateway for unifying model access and request controls. KLA governs workflow decisions and exports audit-ready evidence packs.
KLA vs Portkey
Portkey is a strong AI gateway/guardrails layer with production features like RBAC, audit logs, and exports. KLA governs workflow decisions with approvals and evidence exports for audits.
AI governance programs
I need a governance program
Inventories, assessments, reporting, and org-wide compliance workflows.
KLA vs Credo AI
Credo-style platforms are strong for inventories, assessments, and governance artifacts. KLA focuses on runtime workflow governance + evidence exports tied to real executions.
KLA vs Fiddler
Fiddler is strong for AI observability, monitoring, and guardrails programs. KLA focuses on workflow decision governance (checkpoints + queues) and verifiable evidence exports.
KLA vs Holistic AI
Holistic AI is positioned around EU AI Act readiness and governance workflows. KLA is the runtime control plane for agent workflows with evidence exports tied to real executions.
KLA vs Monitaur
