Which one would each critic pick
| Critic | Agent Maestro | Tessera | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.8 | no preference |
| El Crítico | 6.0 | 5.3 | Agent Maestro — It controls extensions it does not ship. A Roo Code or Cline release can change the surface underneath it, and twenty concurrent tasks share one editor process. |
| El Profesor | 6.8 | 6.5 | Agent Maestro — Server-Sent Events for live monitoring and an OpenAPI document at /openapi.json mean the control surface is specified rather than described. |
| La Inversora | 5.5 | 5.8 | Tessera — 299 stars around a control surface for three other companies' agents: the coordination is the contribution, and the vendors underneath are building their own. |
| La Jefa | 5.0 | 5.8 | Tessera — No per-seat cost, and it deploys from a compose file as well as from an installer, which means my platform team can run one instance instead of blessing sixty desktops. |
| El Hacker | 7.8 | 7.5 | Agent Maestro — MIT, and it flips the arrow: Claude Code, Codex or Gemini CLI point at my editor instead of a provider, because it answers /messages and /chat/completions itself. |
