Spec by spec
| Spec | IBM Bob | Trae |
|---|---|---|
| Architecture | ||
| Category | AI-native IDE | AI-native IDE |
| Runs | local | local, cloud |
| Platforms | macos, linux, windows | macos, linux, windows |
| Context window | not documented | not documented |
| Protocols | ||
| MCP client | Yes | Yes |

| Capabilities | ||
| Runs terminal commands | Yes | Yes |
| Multi-file edits | Yes | Yes |
| Git operations | No | Yes |
| Browser control | No | 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 | YesBob spawns subagents that run in parallel, each in its own mode, with per-spawn approval. | Yes |
| Headless / CI mode | YesBob Shell is documented for task scripting and CI/CD pipeline integration. | NoConfirmed false: Trae ships only the desktop IDE; no CLI, print/exec mode or CI runner appears anywhere in the documentation index. |
| Models | ||
| Backbone | multi-model routing | Gemini, GPT, DeepSeek |
| Bring your own model | No | Yes |
| Local models | No | 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. |

| Pricing model | subscription | mixed |
| Starts at | $20/mo | $3/mo |

Which one would each critic pick
| Critic | IBM Bob | Trae | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.8 | 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 | 5.5 | 5.8 | Trae — SOLO mode plans, implements, tests and deploys behind a sandbox whose allowlisted commands are built to walk straight through it, so an agent's mistakes can still ship before anyone reads the diff. |
| El Profesor | 5.5 | 5.5 | no preference |
| La Inversora | 7.0 | 5.8 | IBM Bob — This replaced watsonx Code Assistant, and the premium packages from $20 a month are the real business: the agent is the wrapper, modernisation is the product. |
| La Jefa | 6.5 | 5.5 | IBM Bob — Sixty developers is $1,200 a month on the entry plan and $12,000 on the top one, and the difference between them is an allowance nobody can forecast. |
| El Hacker | 3.8 | 6.0 | Trae — Closed source, but any compatible endpoint with my own key, local models, an mcpServers config and subagents; more knobs than I expected from a ByteDance IDE. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
