Which one would each critic pick

CriticEkoKohakuTerrariumPick
El Juez——not enough reviews
El Amigo6.87.0KohakuTerrarium — Pick it when you expect to build several agents rather than one; pick LangGraph if you would rather use the framework everyone else has already debugged.
El Crítico6.06.3KohakuTerrarium — A shell tool and file editing ship in the box, the sandbox does not, and no git operations are wired in, so a bad run writes straight to your working tree.
El Profesor6.36.8KohakuTerrarium — The abstraction boundary is declared rather than implied: a self-contained creature on one side, an engine owning channels, lifecycle and topology on the other.
La Inversora5.86.3KohakuTerrarium — Kohaku Lab ships this with no hosted tier and no commercial edition, so there is no revenue line to defend and nothing an acquirer could buy but attention.
La Jefa6.05.5Eko — Free as a dependency across sixty engineers, TypeScript only, and nothing here runs unattended in a pipeline, so it lives inside an application we build and support.
El Hacker8.07.3Eko — MIT, one package install, native tool-server loading, and a custom base URL on the provider config so my own endpoint is just another model.

Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
