| Runs | local, cloud | cloud |
| Platforms | macos, linux, windows | macos, linux, windows, web |
| Context window | not documented | not documented |
| Protocols | ||
| MCP client | No | Yes |
| MCP server | No | No |
| Capabilities | ||
| Runs terminal commands | YesOnly in agent mode, where the model runs read-only shell commands such as ls, cat, rg and git to explore the repository before reviewing. | Yes |
| Multi-file edits | No | Yes |
| Git operations | YesIt reads diffs from and writes comments and thread replies to six hosted VCS platforms; it does not commit or push. | Yes |
| Browser control | No | NoReviews and the CLI read code, diffs and connected MCP data only; no browser control or page inspection is documented. |
| Sandboxed execution | No | NoSelf-hosted CodeRabbit "ships as a container image that you run in your own environment", which is a deployment option rather than an isolation sandbox for the agent's own execution. |
| Multi-agent orchestration | No | No |
| Headless / CI mode | Yes | YesThe CLI authenticates non-interactively with an Agentic API key for headless and bot-driven environments, and `--agent` emits structured JSON for automation. |

| Bring your own model | Yes | YesOnly on the self-hosted Enterprise image, which lets you "connect CodeRabbit to your own large language model provider or account"; the SaaS reviewer uses CodeRabbit's own OpenAI and Anthropic access. |
| Local models | YesOllama is a first-class provider. | NoNo custom base URL or local endpoint is documented — provider configuration is shared with Enterprise customers during onboarding rather than published. |

Which one would each critic pick
| Critic | AI Review | CodeRabbit | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.8 | CodeRabbit — CodeRabbit is the PR reviewer I would install today, free on public repos and with a pre-commit CLI that plugs into your coding agent, as long as you treat its comments as a second opinion. |
| El Crítico | 6.3 | 6.5 | CodeRabbit — By the number CodeRabbit itself reports, precision on Code Review Bench is 49.2%, so on that benchmark roughly one comment in two is not a real finding. |
| El Profesor | 7.0 | 6.5 | AI Review — Inline, context and summary prompts are all user-supplied, so the output distribution is a property of a team's configuration rather than of the tool being evaluated. |
| La Inversora | 6.3 | 7.8 | CodeRabbit — Free for public repos is a distribution engine, the $24 to $72 seat ladder is pricing power, and both Git hosts it lives on would rather own it than compete with it. |
| La Jefa | 7.3 | 7.0 | AI Review — It runs inside the CI job we already pay for, with no seat licence and no vendor holding our diffs, which is the shortest procurement conversation of the quarter. |
| El Hacker | 7.8 | 4.3 | AI Review — Apache-2.0, Ollama as a first-class provider, and config from YAML, JSON or environment variables, so a fully local reviewer is a file I write rather than a plan I request. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
