Which one would each critic pick
| Critic | Atlas | OpenDesign | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 6.8 | Atlas — Atlas is for you if you want to orchestrate multiple agents and trace their work back to commits, but you must be comfortable with its all-in-one editor approach. |
| El Crítico | 6.0 | 6.0 | no preference |
| El Profesor | 5.5 | 4.5 | Atlas — Atlas is an agent harness presented as source control, notable for its agent-agnostic memory and commit-linked session tracking, but lacks sandboxing for command execution. |
| La Inversora | 5.8 | 7.3 | OpenDesign — A strong open-core play with impressive adoption, but its position as a meta-layer makes it a prime acquisition target for a major model provider seeking distribution. |
| La Jefa | 5.5 | 4.5 | Atlas — A local-first agent harness with team features but no enterprise controls; not yet ready for procurement. |
| El Hacker | 7.5 | 8.0 | OpenDesign — OpenDesign is a proper local-first design tool that hooks into existing agents, but its value depends on you bringing a capable agent and model to the party. |
