| Git operations | Yes | YesSeer creates pull requests on GitHub and merge requests on GitLab; only the cloud versions of both hosts are supported. |
| Browser control | NoReviews and the CLI read code, diffs and connected MCP data only; no browser control or page inspection is documented. | No |
| Sandboxed execution | 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. | No |
| Multi-agent orchestration | No | No |
| Headless / CI mode | YesThe CLI authenticates non-interactively with an Agentic API key for headless and bot-driven environments, and `--agent` emits structured JSON for automation. | Yes |
| Models | ||
| Backbone | OpenAI, Anthropic | undisclosed |
| Bring your own model | 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. | No |
| Local models | NoNo custom base URL or local endpoint is documented — provider configuration is shared with Enterprise customers during onboarding rather than published. | No |

Which one would each critic pick
| Critic | CodeRabbit | Seer | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.8 | 7.0 | 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 | 6.5 | 6.5 | no preference |
| El Profesor | 6.5 | 6.8 | Seer — Context is assembled from traces, logs and profiles rather than from source alone, which is a materially better evidence base than any diff-reading reviewer has. |
| La Inversora | 7.8 | 7.8 | no preference |
| La Jefa | 7.0 | 6.8 | CodeRabbit — Sixty seats on Team is $2,880 a month, it runs on all four Git hosts we could plausibly use, and Enterprise self-hosting exists, so this is a procurement I can actually finish. |
| El Hacker | 4.3 | 4.3 | no preference |
