Which one would each critic pick
| Critic | Julep | VoltAgent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.5 | no preference |
| El Crítico | 5.8 | 6.0 | VoltAgent — No local model support anywhere, so a framework that offers to self-host its console still sends every token to one of three hosted vendors. |
| El Profesor | 6.8 | 6.5 | Julep — Decorated flows compile to a frozen intermediate representation executed in memory during development and on Temporal or DBOS in production, with no published benchmark to check. |
| La Inversora | 6.0 | 6.0 | no preference |
| La Jefa | 6.3 | 6.3 | no preference |
| El Hacker | 7.3 | 7.5 | VoltAgent — MIT with a single npm create scaffold, and the tool registry speaks MCP natively, so my own servers become agent capabilities without an adapter in between. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
