Which one would each critic pick
| Critic | AgentField | Mastra | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.3 | Mastra — Pick Mastra if your team writes TypeScript and already has a Next.js app to put the agent in; pick LangGraph if it writes Python or needs a graph you can inspect. |
| El Crítico | 6.3 | 6.5 | Mastra — The auth code sits in an ee directory under the Mastra Enterprise License, free for development and testing but licensed for production, so a real deployment's first need is the part that is not open. |
| El Profesor | 7.0 | 6.8 | AgentField — The harness layer swaps between its own coding agent and five external ones by changing one argument, which assumes an equivalence nothing has demonstrated. |
| La Inversora | 6.0 | 7.0 | Mastra — Y Combinator W25, a Teams tier at $250 a month, a token gateway at market rate plus 5.5%, and $100 a month per project for a server that stays up; the acquirer is Vercel. |
| La Jefa | 6.3 | 6.5 | Mastra — The Starter tier keeps 100K observability events for 15 days, SSO arrives at the Teams tier, RBAC and audit logs at Enterprise with custom pricing, and support hours are 8 to 5 Pacific on weekdays. |
| El Hacker | 7.8 | 6.5 | AgentField — Apache-2.0, a one-line install or a pip package, MCP served as well as consumed, and LiteLLM in the middle so Ollama is just another route. |
