Which one would each critic pick
| Critic | Cua | VoltAgent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 6.5 | Cua — Pick Cua when an agent has to use desktop software you cannot script; pick Browser Use if the work never leaves a web page, because that is a much smaller problem. |
| El Crítico | 6.5 | 6.0 | Cua — One Python interface spans hypervisors, containers and a hosted fleet, and a virtual machine does not fail the way a container fails, so the abstraction will leak where it hurts. |
| El Profesor | 6.8 | 6.5 | Cua — Cua-Bench evaluates agents on OSWorld, ScreenSpot and Windows Arena, which are third-party suites, and the record carries no scores from any of them. |
| La Inversora | 6.3 | 6.0 | Cua — Open core with a metered cloud on top, in a category the frontier labs are entering directly, which sets a clock on how long the independent layer stays valuable. |
| La Jefa | 6.0 | 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 | 8.5 | 7.5 | Cua — MIT, pip install cua, a driver install script, an MCP server so my own client can drive a desktop, and QEMU or Apple Virtualization locally with no cloud account. |
