Chrome's built-in download manager lacks advanced features like multi-threaded/accelerated downloading. This extension intercepts browser downloads and hands them off to a native download manager (XDown) for faster, more capable downloading.

1. User installs XDown native desktop application on their computer. 2. User installs this Chrome extension. 3. When user clicks a download link in Chrome, the extension intercepts the download event (chrome.downloads.onDeterminingFilename). 4. The extension checks if the file qualifies for interception (based on MIME type and file size > 2MB). 5. If qualified, it gathers download metadata (URL, cookies, referrer, user-agent, file name, content type, size) and sends it to the native XDown app via nativeMessaging (org.xdown.xmsg). 6. If the native app accepts (result=1), the browser download is cancelled and XDown handles the download. 7. Alternatively, user can right-click any link and choose 'XDown Link' from context menu to manually send it to XDown.

目标用户: Users of the XDown native download manager application / Users who want accelerated/multi-threaded downloading beyond Chrome's built-in capabilities / Chinese-speaking users (primary locale is zh_CN)

Cannot inspect the native XDown application (org.xdown.xmsg) to determine if it has paid features or requires login
The xdown.org website content was not inspected for pricing/login information
Some referenced script files (js/web_extension.js, js/xdown_utils.js) are referenced in xdown_settings.html but not present in the extension package — may be missing or bundled differently

付费分析

未识别到付费功能

The extension contains no payment UI, no billing/subscription logic, no license key checks, no upgrade prompts, and no calls to payment platforms. All 'pro' keyword matches are false positives from JavaScript 'prototype' definitions (e.g., CookieManager.prototype.getCookiesForUrl). The extension is a simple bridge/launcher to a local native download manager with no gated features.

登录理由: The extension contains no login UI, no authentication API calls, no account creation flow, and no session/token management. It communicates exclusively with a locally installed native application (org.xdown.xmsg) via nativeMessaging. No login is required to use the extension's core workflow (intercepting downloads and forwarding them to the native app).
