ShardBrowser

Windows system requirements

Installing on Windows

Download the latest version:

Under Assets, pick the installer ShardBrowser.Launcher_<version>_x64-setup.exe. If you need a version that runs without installation, download ShardBrowser-Launcher-portable-win-x64.exe.

Run the downloaded file. Windows SmartScreen may show a warning. Click More info, then Run anyway.

Installing on macOS

Under Assets, download ShardBrowser.Launcher_<version>_aarch64.dmg. This build supports Macs with Apple Silicon processors.

Open the .dmg file and drag ShardBrowser Launcher to Applications. The build is not notarized, so macOS may block the first launch. Run this command in Terminal:

xattr -dr com.apple.quarantine "/Applications/ShardBrowser Launcher.app"

You can also allow the app under System Settings → Privacy & Security → Open Anyway.

Installing on Linux

The Assets section provides .AppImage, .deb and .rpm builds. To run the AppImage, make it executable:

chmod +x ShardBrowser.Launcher_<version>_amd64.AppImage
./ShardBrowser.Launcher_<version>_amd64.AppImage

Install the .deb package with:

sudo apt install ./ShardBrowser.Launcher_<version>_amd64.deb

First launch

After installation and launch, the All profiles home screen opens. The section menu is on the left: profiles, proxies, fingerprints, extensions, bookmarks, automation and your ShardX account.

Adding a proxy

Go to Proxies and click + Add proxies.

In the Add proxies window, choose the type in Type for lines without one (SOCKS5 by default) and paste your proxies, one per line. Supported formats:

host:port
host:port:user:pass
user:pass@host:port
socks5://user:pass@host:port

Lines starting with # are ignored. Proxies you already have (same type, host, port, username and password) are skipped.

Click Preview. In the preview window, click Test all to check the proxies before adding them. After the test every proxy gets a status and a country.

Proxies marked UDP support SOCKS5 UDP and therefore WebRTC, which matters a lot against serious anti-fraud systems. Without the UDP mark the profile switches to TCP-only mode: your IP won't leak, but the traffic may look suspicious to advanced anti-fraud systems. We strongly recommend proxies with UDP support.

Select working only keeps only the working proxies selected. Click Add 1 proxy - the proxy appears in the list.

Creating your first profile

Go to All profiles and click + New profile. You can also import a profile from the clipboard with Import from clipboard.

The New profile window opens with the Basics, Proxy, Fingerprint and Extensions tabs. On Basics, enter a profile name. Here you can also pick a folder, tags and a color, add a note and load a cookies file.

On the Proxy tab, pick a saved proxy from the list. + Add a new proxy lets you add a new one right away.

You don't have to change anything on the Fingerprint tab - ShardBrowser picks a fingerprint for the chosen OS by itself. If you want, choose the operating system (macOS, Windows, Linux, Android), a specific fingerprint, the graphics card, CPU cores, memory, refresh rate and screen resolution.

Click Create profile.

Launching a profile

The profile appears in the list. The profile card opens on the right: proxy, extensions, notes, fingerprint settings, timezone and language (taken from the proxy by default). Click Start.

The browser starts with an isolated fingerprint and proxy. The chrome://shardx start page lists the profile's protections.

Troubleshooting

The app doesn't start

Most likely Microsoft Edge WebView2 Runtime is not installed. Download and install it:

Original Windows 10/11 images already include WebView2. Stripped-down builds may have it removed.
