CAIN-42 vs LangGraph + LangSmith Deployment
LangGraph is the open-source orchestration framework; LangSmith Deployment (GA 2026-05-27) adds durable execution, an Agent Registry, Agents Auth (beta), A2A/MCP endpoints, self-host/BYOC and evaluations and tracing.
What LangGraph + LangSmith Deployment does well
- The most widely adopted agent orchestration framework.
- Durable execution, human-in-the-loop and deep tracing/evals.
- Large ecosystem, community and SDK integrations.
What CAIN-42 does differently
- Enforces at the tool-call boundary, before anything runs.
- Orders authorization through a Byzantine quorum (3-of-4): one "yes" is never enough.
- Leaves a per-action signed receipt you can verify offline with a clean-room verifier.
- Authority continuity: a change to the model, tool, memory, skill or delegation forces a re-check.
- Self-serve from $19.75/mo; runs hosted, self-hosted or air-gapped.
Capability difference
| Capability | CAIN-42 | LangGraph + LangSmith Deployment | Source (verified 2026-10-14) |
|---|---|---|---|
| Primary focus | Runtime governance in the execution path | Agent orchestration + observability and evals | LangGraph source page verified 2026-10-14 |
| Blocks the tool call at the boundary | Yes — MCPGate halts before the tool runs | Partial (authz at the API; enforcement in app) | |
| Byzantine-ordered authorization (quorum cert) | Yes — 3-of-4 PBFT quorum certificate | No* | |
| Per-action signed receipt, offline-verifiable | Yes — Ed25519, hash-chained, offline-verifiable | Traces / evals (not signed evidence) | |
| Active fail-closed blocking | Yes | Passive: observe and evaluate | |
| Public entry price | $19.75/mo self-serve | Free OSS; platform usage-based |
When to pick which
Pick LangGraph + LangSmith to build and observe agents. Pick CAIN-42 as the active, fail-closed enforcement and evidence boundary in front of the tools those agents call.
