Which one would each critic pick
| Critic | Promptise Foundry | VoltAgent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 8.0 | 6.5 | Promptise Foundry — Pick Promptise Foundry if you are building a production multi-agent system from scratch and need built-in governance, security, and runtime management. |
| El Crítico | 6.5 | 6.0 | Promptise Foundry — Promptise Foundry sells a full-stack agentic engineering framework but omits the core capabilities for code generation and repository management. |
| El Profesor | 5.3 | 6.5 | VoltAgent — A supervisor delegates to sub-agents while tools arrive through a registry with native MCP integration, so tool binding is a lookup rather than code written per agent. |
| La Inversora | 5.5 | 6.0 | VoltAgent — Classic open core: the framework is given away and the observability console is the product, which means the dependency is free and the visibility is what gets billed. |
| La Jefa | 5.0 | 6.3 | VoltAgent — Nothing per seat for the framework, it runs unattended in our pipeline, and the console can be deployed on our own infrastructure, which answers the residency question. |
| El Hacker | 8.0 | 7.5 | Promptise Foundry — Promptise Foundry is a proper Apache-2.0 framework for building and running agents with native MCP, local model support, and a focus on production concerns. |
