* feat(managed-agent): bound half-open Hosted event streams behind a keepalive capability (#14135) The Harness advertises its events-route keepalive as event-keepalive/1, and the Java client arms the idle watchdog only against a Harness that advertises it, so a rolling upgrade never aborts the quiet streams of an older Harness. The abort is now the typed HostedHarnessStreamIdleException: the coordinator retries it through the existing re-attach path and never settles or cancels the Turn on silence alone. The watchdog ticks every tenth of the bound, so an abort lands 45 to 49.5 s after the last byte. HostedEventStreamLivenessIT runs the probes on the packaged chain behind a TCP relay that holds the events connection half-open or stalls it, and the hosted-harness-mysql fork budget grows to 4793 s. A design note records the numbers, the capability, the outcome and the other Hosted streams. Closes #14135 * test(managed-agent): frame relayed requests and see virtual-thread readers in the liveness gate The event-stream relay classified a connection, rewrote its Host header and matched keepalives within single reads, so a request or a keepalive split across TCP segments escaped the stall and half-open injection or the cadence count. It now buffers each request head, forwards the body by its Content-Length, matches keepalives across reads, and records and resets a request it cannot frame. HostedEventStreamRelayTest pins each split. The half-open probe checked reader release with Thread.getAllStackTraces(), which leaves out the virtual threads Turn readers run on. It now reads a JDK thread dump, and first requires that dump to show the parked reader. * test(managed-agent): count each keepalive one relay read carries (#14135) The relay recorded one stamp per read that held a keepalive, so two keepalives in one read counted once, and the split-keepalive case could report a size of 1 whenever the pieces happened to land together. It now counts every match in the read window; the carried tail is a byte shorter than a keepalive, so none counts twice. A new case sends two keepalives in one write. * test(sdk-java): park the published-window probe mid-interval (#14135) The watchdog's ticks run from the stream's creation, and the probe parked right after it. A 2000 ms bound is a whole number of half-budget 1000 ms ticks, so that park sat on a tick of the mutant too, and wherever the scheduler ran a few ms late (macOS) the mutant aborted at ~2000 ms and passed. Parking 300 ms in puts the park mid-interval for both ticks: the shipped 200 ms tick aborts at 2100 ms and a 1000 ms tick at 2700 ms, so the limit drops to 2400 ms. |

The open-source AI coding agent for your terminal, editor, desktop, browser, and chat.

Why Qwen Code?
- Agentic out of the box — Auto-Memory, Auto-Skills, SubAgents, Agent Teams, and MCP. Dynamic workflows, zero setup.
- Open-source, inside and out — The framework and the Qwen models are open-source. They evolve together. No vendor lock-in.
- Multi-protocol — Supports OpenAI, Anthropic, Gemini, and Qwen APIs. Any third-party provider or local model (Ollama / vLLM). Switch at runtime.
- Beyond the terminal — IDE plugins, Desktop app, Web UI, SDKs, and chat integrations (Telegram / DingTalk / WeChat / Feishu).
Tip
Qwen Code is actively iterating on itself — using its own agent and models to file issues, submit PRs, review code, and run tests. Powered by the community, driven by AI.
Installation
Linux / macOS:
curl -fsSL https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen-standalone.sh | bash
Windows:
irm https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen-standalone.ps1 | iex
Restart your terminal after installation to ensure environment variables take effect.
NPM / Homebrew
NPM (requires Node.js 22+):
npm install -g @qwen-code/qwen-code@latest
Homebrew (macOS / Linux):
brew install qwen-code
Quick Start
Open a terminal in your project and start Qwen Code:
cd /path/to/your-project
qwen
Inside the session, run /auth to configure your provider and API key. Then try:
Explain this repository and show me where to start.
See the Authentication Guide and Settings Reference for detailed setup.
How to Use Qwen Code
Choose the interface that fits your workflow:
| Interface | Get started |
|---|---|
| Terminal | Run qwen in your project — see Quick Start. |
| Desktop | Download Qwen Code Desktop for macOS, Windows, and Linux. |
| Web | Run qwen serve --open to open the Web UI in your browser. (experimental) |
| Editor | Set up VS Code, Zed, or JetBrains. |
| Chat | Connect Telegram, DingTalk, WeChat, or Feishu, then run qwen channel start. |
For automation and custom integrations:
- Headless — Run
qwen -p "..."in scripts, CI/CD, or batch jobs. - SDKs — Build with TypeScript, Python, or Java.
- Daemon — Run
qwen serveto connect clients over HTTP + SSE (ACP). (experimental) Daemon guide.
SDK example (Python)
import asyncio
from qwen_code_sdk import is_sdk_result_message, query
async def main() -> None:
result = query(
"Summarize the repository layout.",
{
"cwd": "/path/to/project",
"path_to_qwen_executable": "qwen",
},
)
async for message in result:
if is_sdk_result_message(message):
print(message["result"])
asyncio.run(main())
Capabilities
If you know Claude Code, you already know Qwen Code — and then some. We've put significant effort into bringing Qwen Code to feature parity with Claude Code, improving both breadth and reliability across the board.

Acknowledgments
This project was originally based on Google Gemini CLI v0.8.2. We gratefully acknowledge the Gemini CLI team's excellent work. Starting from Qwen Code v0.1, we stopped syncing with upstream and began independent development as a multi-protocol, multi-platform agent framework with deep integrations for Qwen models and beyond.
