| Who it's not for | Non-technical teams wanting no-code automations | Small teams needing predictable monthly costs |
| Privacy | Multiple public vulnerabilities in 2025-2026 across LangChain, LangGraph, and LangSmith; patched, but ongoing patching discipline is mandatory.⁶ | Active CVE program, but 2026 brought a publicized agent escape and Codex vulnerabilities. |
