Which one would each critic pick
| Critic | Langflow | OpenAI Agents SDK | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.0 | Langflow — Pick Langflow when you need a colleague who does not write Python to see and change the flow; pick Dify if the goal is a finished application rather than a diagram. |
| El Crítico | 6.8 | 6.8 | no preference |
| El Profesor | 7.5 | 6.5 | Langflow — The visual layer sits over a Python runtime, so the graph is executed rather than transpiled, and the same graph can be exposed as tools to external clients over MCP. |
| La Inversora | 7.5 | 7.5 | no preference |
| La Jefa | 6.8 | 7.3 | OpenAI Agents SDK — As a dependency it costs nothing per seat, is maintained by the vendor already on our invoice, and sends traces to that vendor's dashboard by default, which is a retention question. |
| El Hacker | 8.8 | 7.5 | 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. |
