| Multi-file edits | Yes | Yes |
| Git operations | Yes | Yes |
| Browser control | YesBrowser output is attached to tasks and screenshots are captured through browser automation. | YesAI can drive TraeCode's built-in browser tab - opening pages, clicking, filling forms and validating rendering - or an external Chrome instance, once enabled under Settings > Browser (https://docs.trae.ai/ide/browser-use). The built-in Chat agent cannot control the browser. |
| Sandboxed execution | No | YesAgent commands run in a restricted, isolated environment with per-project filesystem and network policy in ~/.trae/sandbox.json; Linux isolation is implemented via bubblewrap, and allowlisted command prefixes deliberately bypass the sandbox. |
| Multi-agent orchestration | No | Yes |
| Headless / CI mode | No | NoConfirmed false: Trae ships only the desktop IDE; no CLI, print/exec mode or CI runner appears anywhere in the documentation index. |

| Bring your own model | Yes | Yes |
| Local models | YesOllama ships as a named provider preset, and base URLs are editable so any OpenAI-compatible or Anthropic-compatible endpoint can be added. | YesThe custom-model flow accepts an arbitrary API format, request URL and key, so any self-hosted OpenAI- or Anthropic-compatible endpoint works alongside the preset providers. |

Which one would each critic pick
| Critic | Kun | Trae | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.8 | Trae — Try Trae if you are price sensitive and building personal projects; think twice if your employer will ask where the prompts go, because the vendor is ByteDance. |
| El Crítico | 5.8 | 5.8 | no preference |
| El Profesor | 6.5 | 5.5 | Kun — The graphical client and the terminal client both attach to one local runtime, so threads, plans and approvals are shared state rather than two synchronised copies. |
| La Inversora | 5.0 | 5.8 | Trae — A $3 Lite tier from ByteDance is subsidized distribution, not a business, and the buyer's risk is geopolitical rather than financial. |
| La Jefa | 4.8 | 5.5 | Trae — Enterprise means contacting BytePlus, the pricing page lists no SSO or audit log, and the security questionnaire's first question is where the prompts go; not yet. |
| El Hacker | 6.5 | 6.0 | Kun — PolyForm Noncommercial, so I can read it and never ship a competing fork, but Ollama is a named preset and every base URL is editable. |
