| Browser control | YesThe built-in Computer Controller extension drives macOS apps including the browser through the Peekaboo CLI, rather than via a dedicated CDP or Playwright tool. | YesBrowser and terminal control helpers ship with the npm and release builds; source builds need those helper binaries on PATH or configured in local-control settings. |
| Sandboxed execution | Yes`goose session|run --container <id>` executes extensions inside an existing Docker container; goose itself runs unsandboxed on the host otherwise. | NoZero ships a native Linux sandbox helper using seccomp rather than Docker; source builds must build the `zero-linux-sandbox` helper separately. |
| Multi-agent orchestration | Yes | Yes |
| Headless / CI mode | Yes | Yes`zero exec` returns exit codes and has a documented GitHub Action recipe. |

Which one would each critic pick
| Critic | goose | Zero | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.3 | no preference |
| El Crítico | 6.5 | 6.8 | Zero — Package builds ship the browser and terminal control helpers; a source build needs those binaries on PATH and expects you to build the Linux sandbox helper separately. |
| El Profesor | 6.5 | 7.3 | Zero — Sessions can be resumed or forked, which makes a continuation a controlled variable, and the headless mode emits text, JSON or stream-JSON rather than prose only. |
| La Inversora | 5.3 | 5.5 | Zero — A permissively licensed terminal agent from a single publisher, in the most crowded category on this board, with nothing being sold at any point. |
| La Jefa | 5.8 | 6.8 | Zero — Nothing to license for sixty, and it is the rare tool that returns meaningful exit codes with a documented continuous integration recipe, so it can gate a build. |
| El Hacker | 9.3 | 8.5 | goose — Rust, Apache-2.0, every extension an MCP server in YAML, Ollama on my box, a foundation instead of a vendor; this is the one I would build if I had the time. |
