Which one would each critic pick
| Critic | Dify | LangChain | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 8.0 | 7.8 | Dify — Pick Dify when people who are not engineers need to build and change LLM applications; pick n8n if the hard part is connecting systems rather than handling documents and prompts. |
| El Crítico | 7.3 | 7.3 | no preference |
| El Profesor | 7.8 | 7.3 | Dify — Retrieval, model management and orchestration are separated into distinct subsystems, and finished workflows are exposed over OpenAPI, so an application becomes a callable service. |
| La Inversora | 8.0 | 7.8 | Dify — One hundred and fifty thousand stars is the largest open-source distribution in this class, and LangGenius monetises it with annual cloud plans from $590 rather than a meter. |
| La Jefa | 7.3 | 7.0 | Dify — Self-hosting costs infrastructure and an owner; the hosted Team plan is $1,590 a year, which is trivial, and everything my security review needs sits in the tier priced by conversation. |
| El Hacker | 7.8 | 8.5 | LangChain — MIT, 24,000 forks, Ollama and HuggingFace as first-class providers, and one pip extra, langchain[mcp], to turn any MCP server into tools; the hosted platform is a choice, not a requirement. |
