Which one would each critic pick
| Critic | Langflow | Strands Agents | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.8 | Strands Agents — Pick Strands if your team writes both Python and TypeScript and wants one agent SDK for both; pick LangGraph when a run must pause for a day and resume where it stopped. |
| El Crítico | 6.8 | 7.3 | Strands Agents — Command execution is a documented capability and no container isolation is listed, so an agent loop that goes wrong does so inside your own process with your own permissions. |
| El Profesor | 7.5 | 7.5 | no preference |
| La Inversora | 7.5 | 8.0 | Strands Agents — The SDK is free because the inference is not: it comes from a cloud provider whose own model service is the first-listed provider, and that is the entire business model. |
| La Jefa | 6.8 | 7.8 | Strands Agents — Nothing per seat, it runs unattended in our pipeline, and the maintainer is a vendor we already have a master agreement with, which removes the entire procurement step. |
| El Hacker | 8.8 | 8.5 | 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. |
