Spec by spec
| Spec | Chorus | CodeRabbit |
|---|---|---|
| Architecture | ||
| Category | Code review agent | Code review agent |
| Runs | local | cloud |
| Platforms | macos, linux, windows | macos, linux, windows, web |
| Context window | not documented | not documented |
| Protocols | ||
| MCP client | No | Yes |
| MCP server | Yes | No |
| Capabilities | ||
| Runs terminal commands | Yes | Yes |
| Multi-file edits | NoChorus reviews rather than edits; the fix goes back to whichever agent wrote the code. | Yes |
| Git operations | No | 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 | YesA run fans the same diff out to two to four different vendor CLIs in parallel and compares their verdicts. | No |
| Headless / CI mode | YesChorus can be called from scripts and CI, though calling it from `codex exec` requires --dangerously-bypass-approvals-and-sandbox because Codex blocks MCP tools there. | YesThe CLI authenticates non-interactively with an Agentic API key for headless and bot-driven environments, and `--agent` emits structured JSON for automation. |
| Models | ||
| Backbone | Claude Code, Codex CLI, Gemini CLI, OpenCode, Kimi CLI | OpenAI, Anthropic |
| 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 | No | 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 | Chorus | CodeRabbit | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 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 | 6.8 | 6.5 | Chorus — Calling it from codex exec requires --dangerously-bypass-approvals-and-sandbox, so the automated path to one of its own reviewers runs with the guard rails switched off. |
| El Profesor | 7.3 | 6.5 | Chorus — Agreement between vendors is used as the pass condition, which substitutes inter-rater consensus for correctness with no published relationship between the two. |
| La Inversora | 6.5 | 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 | Chorus — A global npm install on sixty desks, no seat licence, and a review step that genuinely runs headless: cheap, unmanaged, and invisible to every system I report from. |
| El Hacker | 8.0 | 4.3 | Chorus — Apache-2.0, chorus init registers it as an MCP server with every CLI and IDE it finds, exposing nine tools, and the daemon and its history stay on my machine. |
