Which one would each critic pick
| Critic | Langflow | Qwen-Agent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 8.0 | Qwen-Agent — Pick Qwen-Agent if you are building on Qwen models and want the framework the vendor uses itself; pick a neutral framework if you expect to change model families next year. |
| El Crítico | 6.8 | 6.8 | no preference |
| El Profesor | 7.5 | 7.0 | 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 | 8.5 | Qwen-Agent — 17,063 stars and a trillion-dollar owner. This is not a product, it is customer acquisition for a model business, and it has been running since September 2023. |
| La Jefa | 6.8 | 7.0 | Qwen-Agent — No seat cost across sixty engineers and nothing for me to administer, except a browser extension example that my endpoint policy will want to discuss at some length. |
| 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. |
