Which one would each critic pick
| Critic | Kimi Agent SDK | Nanocodex | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.3 | Nanocodex — Pick it when you are shipping a product with a coding agent inside it; pick Sandbox Agent when you would rather talk to the agent over HTTP than link it. |
| El Crítico | 6.5 | 6.5 | no preference |
| El Profesor | 7.3 | 7.3 | no preference |
| La Inversora | 7.0 | 6.3 | Kimi Agent SDK — 575 stars and a first-party SDK from a model vendor with no free tier: this is not a product, it is a demand-generation instrument, and it is a good one. |
| La Jefa | 7.0 | 6.0 | Kimi Agent SDK — Go, Node and Python clients and a runtime that genuinely runs headless: the rare row where the integration work lands in a pipeline instead of on a desk. |
| El Hacker | 6.8 | 7.8 | Nanocodex — Dual licensed MIT or Apache-2.0, one line with cargo add or npm install, and a wasm32 target that puts the whole loop inside a browser tab. |
