Which one would each critic pick
| Critic | Koog | Rivet | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 7.3 | Rivet — Pick it when the agent logic has to be legible to people who will not read your code; pick a plain framework when the only audience is engineers. |
| El Crítico | 6.0 | 6.5 | Rivet — The artefact you ship is a graph project authored in a desktop editor, which means the unit your team reviews and merges is not something a reviewer can read as code. |
| El Profesor | 6.8 | 7.0 | Rivet — The same graph the editor executes is executed in production by a separate TypeScript library, so what is observed during debugging is the artefact itself rather than a model of it. |
| La Inversora | 6.3 | 6.5 | Rivet — Ironclad is a contract software company, and this is 4,686 stars of developer goodwill attached to a project that is not what the company sells. |
| La Jefa | 6.5 | 6.0 | Koog — It integrates with Spring Boot and Ktor, so it deploys into services we already run, and support goes through the vendor's existing issue tracker rather than a stranger's inbox. |
| El Hacker | 7.8 | 6.8 | Koog — Apache-2.0, one Maven coordinate, Ollama is in the provider list with its own continuous integration workflow, and agents can be exposed over ACP as well as consuming MCP tools. |
