YunX

Project Overview

YunX is a completely free and open-source Android app for parsing cloud-drive share links: paste a link, get the direct URL, and download at full speed with ranged parallel chunks and resume support, bypassing the official clients' throttling.

It covers ten drives including Quark, UC, Thunder, Baidu, 139, 123, 115, Guangya and Lanzou, auto-matches extraction codes, cleans temporary transfers after fetching links, and encrypts credentials with an AES-GCM key derived from your password, all locally on the phone.

Item	Value
Platform	Android (minSdk 24+)
Stack	Kotlin + Jetpack Compose (Material 3)
Supported drives	Quark, UC, Thunder, Baidu, 139, 123, 115, Guangya, Lanzou and 10 in total
License	AGPL-3.0

Paste a link and download at full speed, ten cloud drives in one free app.

Key Features

• Share link parsing: recognizes share links from Quark, UC, Thunder, Baidu, 139, 123, 115, Guangya, Lanzou and Lanzou Youxiang, auto-matching extraction codes
• Fast downloads: ranged parallel chunks with resume support, tasks keep headers and fixed chunk plans, up to 32 concurrent
• Transfer cleanup: temporary transfers on Baidu, Thunder and Guangya are cleaned after link fetching; Quark transfers are kept until the task finishes or is deleted
• Multi-platform login: WebView cookies, account passwords, SMS codes and JWT flows adapted per drive
• Credential backup: cookies and JWTs encrypted with AES-GCM using a key derived from your password
• Clipboard detection: copy a share link and the app offers one-tap paste and parse
• Download manager: pause, resume, delete and open tasks with clear progress

Target Audience

• Users saving resources from cloud-drive chat groups
• Heavy downloaders tired of client-side throttling
• Users with scattered accounts across many drives
• Privacy-minded users wanting an open-source parser

Quick Start

1. Download the APK from Releases and install
2. Log in to your drives on the Drives page
3. Copy a share link and paste it on the Parse page (extraction code optional)
4. Browse the share, tap a file to get its direct link
5. Manage tasks on the Downloads page with pause, resume, delete and open

Core Advantages

• Free and open: AGPL-3.0 licensed, any paid copy is a repackaged scam
• Direct-link downloads: skips the official client channel, parallel chunks saturate bandwidth
• Credentials stay local: login states are encrypted on device, backups encrypted too
• Wide coverage: ten mainstream drives out of the box

System Requirements

Item	Requirement
OS	Android 7.0+ (minSdk 24)
Network	Internet access to drive APIs
Build	Android Studio or AndroidIDE, Gradle + KSP
