Which one, for what

Qwen Code BB

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

  • Reliability, 69 against 63
  • Schema & documentation, 91 against 72
  • Agent ergonomics, 85 against 67
  • Maintenance & community, 88 against 82

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

Best 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
