CAIN-42 CAIN StudioHow CAIN-42 compares
CAIN-42 vs LangSmith / Galileo
LangSmith (LangChain) and Galileo are leading agent observability and evaluation platforms: tracing, evals, monitoring, sometimes runtime guardrails. They tell you what your agents did; CAIN-42 decides whether an action may run and proves it.
At a glance
What LangSmith / Galileo does well
- Mature tracing, evaluation and monitoring for LLM/agent apps.
- Large framework ecosystem and integrations.
- Free developer tiers and mature docs.
What CAIN-42 does differently
- Enforces at the tool-call boundary, before anything runs.
- Orders authorization through a Byzantine quorum (3-of-4), so a single yes is never enough.
- Leaves a per-action signed receipt you can verify offline with a clean-room verifier.
- Self-serve from $19.75/mo; the free tier includes the whole decision path.
- Runs hosted, self-hosted, or air-gapped on your own KMS root of trust.
Capability difference
| Capability | CAIN-42 | LangSmith / Galileo |

| Byzantine-ordered authorization (quorum cert) | Yes | No |
| Per-action signed receipt, offline-verifiable | Yes | No |
| Tracing, evals, online monitoring | Partial (decision traces) | Yes (core strength) |
| CI/CD eval gates | Partial (conformance suite) | Yes |
| Self-serve start | Yes | Yes |
When to pick which
Pick LangSmith/Galileo to measure and improve agent quality. Pick CAIN-42 when quality is not the risk — when an agent can act, and you need authorization and proof at the execution boundary.
