Which one would each critic pick
| Critic | Background Agents (Open-Inspect) | SWE-agent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 5.0 | Background Agents (Open-Inspect) — Pick Open-Inspect if your backlog is full of well-specified tickets; pick an interactive agent if the work needs a conversation before anyone knows what to build. |
| El Crítico | 6.0 | 4.8 | Background Agents (Open-Inspect) — It is documented as designed for single-tenant deployment inside one trusted organisation, and it can also be started by inbound webhooks and third-party alerts. |
| El Profesor | 7.0 | 5.8 | Background Agents (Open-Inspect) — Pull requests carry commit attribution back to the person who prompted the run, which preserves provenance through the artefact rather than only in a log. |
| La Inversora | 6.3 | 4.0 | Background Agents (Open-Inspect) — 2,724 stars for an open reconstruction of a company's internal tool, permissively licensed, with no entity and nothing that converts that attention into revenue. |
| La Jefa | 5.3 | 3.8 | Background Agents (Open-Inspect) — No licence cost for sixty engineers, and two of the four model options are documented through consumer subscriptions, which is not a thing procurement can put on a contract. |
| El Hacker | 7.3 | 7.5 | SWE-agent — MIT, Docker-sandboxed, any LiteLLM model including my local server, and every prompt in the repo; maintenance-only just means the code stops changing under me. |
