Installing on Windows
Download the latest release:
github.comhttps://github.com/ProxyShard/ShardBrowser/releases/latestUnder Assets, pick the .exe or .msi file.
Run the downloaded file. Windows SmartScreen may show a warning - click More info, then Run anyway.
The installer will finish in a few seconds.
Installing on macOS
Download the latest release:
github.comhttps://github.com/ProxyShard/ShardBrowser/releases/latestUnder Assets, pick the aarch64.dmg file.
Open the downloaded .dmg and drag ShardX Launcher into the Applications folder.
Bypassing Gatekeeper
This step is mandatory. macOS blocks all unsigned apps - without it the application will not open.
Open Terminal using one of two methods:
- Spotlight: press
⌘ + Space, typeterminal, select the app
- Finder: Applications -> Utilities -> Terminal
Paste the command and press Enter:
xattr -dr com.apple.quarantine "/Applications/ShardX Launcher.app"
After that, open the app via Spotlight (⌘ + Space → shardx) or from the Applications folder.
First Launch
On first launch ShardX downloads the browser engine from CDN (about 198 MB, one time only). Wait for the download to finish.
Once done, the main Browsers screen will open.
Adding a Proxy
Go to the Proxies section and click + New proxy.
In the Bulk import proxies window, paste your proxies one per line. Supported formats:
host:port
host:port:user:pass
scheme://host:port
scheme://user:pass@host:port
Click Test all to check the proxies before importing.
After testing, each proxy gets a status. Proxies with the UDP label support SOCKS5 UDP, which means WebRTC too - very useful when working with serious antifraud systems. If there is no UDP label, the browser profile automatically switches to TCP-only mode: your IP won't leak, but traffic may look suspicious to advanced antifraud systems. We strongly recommend using proxies with UDP support.
Click Import - the proxy will appear in the list with status Active.
Creating Your First Profile
Go to the Browsers section and click + New profile.
No need to change the default settings - ShardX will generate a unique fingerprint automatically. Make sure to select a proxy in the Proxy field at the bottom of the form.
Click Create profile.
Launching a Profile
Click Start - the browser will open with an isolated fingerprint and proxy.
Troubleshooting
Windows: the app won't start
Most likely Microsoft Edge WebView2 Runtime is not installed. Download and install it:
developer.microsoft.comhttps://developer.microsoft.com/en-us/microsoft-edge/webview2/consumerOriginal Windows 10/11 images already include WebView2. On stripped-down builds it may have been removed.
macOS: "ShardX Launcher is damaged and can't be opened"
This is a standard Gatekeeper block. Follow the steps in Bypassing Gatekeeper - both ways to open Terminal and the command to remove the quarantine flag are described there.
