Spec by spec
| Spec | Kiro | Trae |
|---|---|---|
| Architecture | ||
| Category | AI-native IDE | AI-native IDE |
| Runs | local, cloud, sandbox | local, cloud |
| Platforms | macos, linux, windows, web | 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 | Yes | Yes |
| Browser control | YesEvery Kiro Web sandbox ships a headless Chrome with Playwright MCP, the agent-browser CLI and the Chrome DevTools MCP server preinstalled; the local IDE and CLI have no built-in browser tool. | 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 | YesKiro Web runs each task in its own isolated execution environment with configurable access controls. | 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 | Yes | Yes |
| Headless / CI mode | Yes | NoConfirmed false: Trae ships only the desktop IDE; no CLI, print/exec mode or CI runner appears anywhere in the documentation index. |
| Models | ||
| Backbone | Claude, GPT, DeepSeek, Qwen, MiniMax, GLM | Gemini, GPT, DeepSeek |
| Bring your own model | NoKiro exposes a picker over its own curated model list plus an Auto router; no custom base URL, Bedrock deployment or self-hosted endpoint is documented. | Yes |
| Local models | NoNo local or OpenAI-compatible endpoint is documented; only Kiro-hosted models are selectable. | 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. |
| Cost | ||
| Pricing model | mixed | mixed |
| Starts at | $20/mo | $3/mo |
| Free tier | Yes | Yes |
| Bring your own key | NoKIRO_API_KEY for headless runs is a Kiro platform token billed against Kiro credits, not your own provider or AWS account key. | Yes |

Which one would each critic pick
| Critic | Kiro | Trae | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 6.8 | Kiro — Pick Kiro if you want an agent that makes you write requirements and a design before it touches code, and accept that the bill is a credit meter you cannot route around with your own key. |
| El Crítico | 6.3 | 5.8 | Kiro — Kiro meters every task in credits with per-model multipliers and no key of your own, and the headless CLI ships a --trust-all-tools flag that turns off the only approval gate it has. |
| El Profesor | 6.5 | 5.5 | Kiro — Kiro's spec-first pipeline is a principled ordering, requirements before design before tasks before code, but no benchmark and no published evaluation accompanies it. |
| La Inversora | 7.8 | 5.8 | Kiro — Kiro is AWS's entry, and the question is never whether AWS can fund it, only whether AWS keeps caring. |
| La Jefa | 7.0 | 5.5 | Kiro — SSO and centralized billing exist, steering files make rules enforceable, and the meter has an admin-controlled overage switch; approved with conditions. |
| El Hacker | 4.3 | 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.
