“It accepts image input in a terminal, a sentence that would have ended a career in 2019.”

| Multi-file edits | Yes | Yes |
| Git operations | Yes | Yes |
| Browser control | Yes | 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 | 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. |
| Models | ||
| Backbone | Claude | OpenAI, Anthropic, Gemini, Groq, OpenRouter, DeepSeek, Mistral, xAI, Qwen, Kimi, GitHub Models, Fireworks, MiniMax, Ollama, LM Studio |
| Bring your own model | YesThrough Amazon Bedrock, Google Cloud's Agent Platform, Microsoft Foundry, or any LLM gateway your organisation runs, with model IDs pinned per deployment. | Yes |
| Local models | NoClaude Code routes only to Claude models. Anthropic states it does not support routing Claude Code to non-Claude models through any gateway, and gateway model discovery drops every model ID that does not contain "claude" or "anthropic", so a local Ollama or LM Studio endpoint is not a supported setup. | Yes |

Which one would each critic pick
| Critic | Claude Code | Zero | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.8 | 7.3 | Claude Code — Use it if you live in the terminal and can pay for Max or an API key; it is the strongest terminal agent here for real repositories. |
| El Crítico | 6.8 | 6.8 | no preference |
| El Profesor | 6.8 | 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 | 8.5 | 5.5 | Claude Code — Anthropic owns the model, the distribution and the invoice, which is the rarest kind of moat in this category. |
| La Jefa | 7.0 | 6.8 | Claude Code — Team seats at $20 with SSO, Enterprise for audit logs; the metered part is what sixty engineers on agentic tasks will actually cost. |
| El Hacker | 5.0 | 8.5 | Zero — MIT, twenty-five providers with Ollama and LM Studio among them, and it works as an MCP server as well as a client, so my tools go both ways. |
