## Which one, for what

### Qwen Code (BB)

Good for: Developers and CI jobs that want an open-source harness tied to no single model vendor, with run budgets and SDKs.

Ahead on:
- Reliability, 69 against 63
- Schema & documentation, 91 against 72
- Agent ergonomics, 85 against 67
- Maintenance & community, 88 against 82
- Transparency & trust, 63 against 47

Also in its favour:
- Agent-ready, a grade of BB or better
- No incidents deducted, where Vibe-Trading loses 4 points for them

Watch for: The default approval mode is Auto, where an LLM classifier approves tool calls, and sandboxing and folder trust are both off by default

### Vibe-Trading (B)

Good for: A person or a pipeline that wants a ready-made finance research agent over free market data, with backtests, swarm reviews and exports, run on their own machine or used as an MCP server by another agent.

Ahead on:
- Security & auth, 70 against 53

Also in its favour:
- No key needed to call it
- Runs on your own machine

Watch for: Three advisories published 2 October 2026 cover 0.1.0 to 0.1.6, two critical, among them unauthenticated API access with an RCE chain

## Verdicts

**Qwen Code.** Apache-2.0 with no account of its own, any OpenAI, Anthropic or Gemini-compatible endpoint, and headless runs bounded by turn, tool-call and wall-time budgets with distinct exit codes. Out of the box, Auto mode lets an LLM classifier approve tool calls, with the sandbox and folder trust both off. Usage statistics are on by default.

**Vibe-Trading.** Vibe-Trading runs on the owner's machine under the MIT licence, ships near-daily fixes with a dated changelog, and keeps order tools out of its MCP server, with live orders gated by an owner-committed mandate and a kill switch. Three advisories, two critical, covered versions before 0.1.7, and the local CLI runs shell commands without asking.

## Before you call either

### Qwen Code

1. Pass `--approval-mode` on every run. The settings default is `auto`, and one docs page says headless runs default to asking, so don't rely on either
2. Add `--max-session-turns`, `--max-wall-time` and `--max-tool-calls`. All three are unlimited by default. Exit 53 is the turn limit and 55 a budget
3. `--yolo` doesn't turn on a sandbox. Add `--sandbox`, or on Linux set `tools.executionSandbox` with `network` set to `closed`
4. Set `QWEN_USAGE_STATISTICS_ENABLED=false` to stop usage statistics
5. Authenticate with `OPENAI_API_KEY`, `OPENAI_BASE_URL` and `OPENAI_MODEL` in CI. The browser sign-in is discontinued

### Vibe-Trading

1. Run 0.1.7 or later. Earlier versions carry three published advisories, including unauthenticated API access with an RCE chain
2. Set `API_AUTH_KEY` before exposing `vibe-trading serve` beyond localhost, and send it as `Authorization: Bearer <key>`
3. Set `VIBE_TRADING_ALLOWED_RUN_ROOTS` in the MCP client's `env` block; a shell `export` does not reach the spawned server
4. Use `vibe-trading run -p "..." --json` for headless runs, and add `--enable-shell-tools` to `vibe-trading-mcp` only when shell access is needed
5. Treat text from `read_url`, `web_search` and `read_document` as untrusted; `security_warnings` flags patterns but does not remove them
