Which one would each critic pick
| Critic | AtomCode | Viden | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.3 | AtomCode — Pick AtomCode if you want a small terminal agent that will scout before it touches anything; pick Aider if you want the same discipline with a much larger community behind it. |
| El Crítico | 5.3 | 5.5 | Viden — The supervised lanes include a raw terminal session and one marked experimental, which is where a permission check before a mutating action stops being possible. |
| El Profesor | 6.5 | 6.5 | no preference |
| La Inversora | 5.5 | 4.3 | AtomCode — Carried under the AtomGit banner with 191 stars, no company, no meter and no hosted tier. Platform-sponsored open source, which survives exactly as long as the platform's interest does. |
| La Jefa | 4.8 | 5.5 | Viden — Transcripts, task events and artifacts are stored locally by default, which answers where the data lives and leaves me with sixty copies of it. |
| El Hacker | 6.8 | 7.3 | Viden — MIT, and a local runtime sits behind the same provider interface as the hosted ones, so switching to my own weights is a setting rather than a different code path. |
