Which one would each critic pick
| Critic | Mastra | Spring AI Alibaba | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.3 | no preference |
| El Crítico | 6.5 | 6.3 | 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 | 6.8 | 7.0 | Spring AI Alibaba — Context engineering is exposed as named hooks rather than folklore: compaction, context editing, tool retry, call limits and dynamic tool selection are configuration, not prompt craft. |
| La Inversora | 7.0 | 6.3 | 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 | 6.5 | 6.3 | 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 | 6.5 | 6.8 | Spring AI Alibaba — Apache-2.0 from a Maven coordinate, tool servers managed from the console, agent-to-agent messaging supported, and no local model path recorded on the board. |
