Which one would each critic pick
| Critic | Open Code Review | Seer | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 7.0 | Seer — Pick Seer if your error backlog is the bottleneck and you already run Sentry; pick Baz if what you actually want is a sharper reviewer on every diff. |
| El Crítico | 6.0 | 6.5 | Seer — Pull requests and merge requests are supported only on the cloud versions of both hosts, so a self-managed installation is excluded from the fix half of the product. |
| El Profesor | 6.8 | 6.8 | no preference |
| La Inversora | 6.8 | 7.8 | Seer — Selling this as an add-on to an existing subscription is the cheapest distribution in the category: the data moat was already paid for by the monitoring product. |
| La Jefa | 6.0 | 6.8 | Seer — Billing is per active contributor, defined as anyone opening two or more pull requests a month in an enabled repository, so my headcount is not the number that bills. |
| El Hacker | 8.0 | 4.3 | Open Code Review — Apache-2.0, a global npm install, and an MCP client, so I can bolt my own servers onto the review and read every rule that produced a comment. |
