Which one would each critic pick
| Critic | Langflow | LangGraph | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.8 | LangGraph — Pick LangGraph if your agent has to stop, wait for a human, and resume a day later without losing state; pick CrewAI if you want roles and less plumbing. |
| El Crítico | 6.8 | 7.3 | LangGraph — The core is standalone, but local models arrive through LangChain's ChatOllama and MCP through langchain[mcp], so the dependency you were told you did not need is the one that ships the tools. |
| El Profesor | 7.5 | 7.5 | no preference |
| La Inversora | 7.5 | 7.8 | LangGraph — The library is the funnel and LangSmith is the company: a free Developer tier with 5k traces, named logos like Klarna, Uber and J.P. Morgan, and an observability business waiting for its acquirer. |
| La Jefa | 6.8 | 7.0 | LangGraph — As a dependency it is $0 per seat until we adopt the hosted deployment, where Plus is $39 a seat, $2,340 a month for sixty, and SSO waits in the Enterprise tier. |
| El Hacker | 8.8 | 8.3 | Langflow — MIT, one docker run to have it on localhost, local model endpoints supported, and it acts as both an MCP client and an MCP server, which almost nothing else does. |
