Which one would each critic pick
| Critic | GitHub Spark | Rork | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 2.8 | 4.8 | Rork — Pick Rork when the target is a native iPhone or Android app and you want real Swift and Kotlin out of it; pick Lovable if the thing you are prototyping lives on the web. |
| El Crítico | 2.3 | 3.8 | Rork — There are two separate credit meters, one for the agent building and one for the finished application running, and no published rate converts either into work. |
| El Profesor | 3.3 | 4.3 | Rork — Generation targets three platform-specific stacks from one prompt and compiles in the browser, and no model, evaluation or build success rate is disclosed anywhere. |
| La Inversora | 2.8 | 5.0 | Rork — Rork, Inc. sells the last mile nobody else covers, walking a generated project through store submission, and the free tier exists to get people to that moment. |
| La Jefa | 2.3 | 3.5 | Rork — No per-seat figure is published anywhere, so I cannot construct a budget line for sixty people, and applications built this way run on infrastructure I do not control. |
| El Hacker | 2.0 | 3.0 | Rork — Closed source, browser only, no key of my own and no local model, so the only thing I can carry away is whatever the repository sync leaves behind. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
