}Works with Playwright, Puppeteer, Selenium, Claude Desktop and Cursor; SDKs for Python, Node.js and Rust.
ShardBrowser is a free anti-detect browser for automation and anonymity. Run your profiles from the desktop app, the local API, the MCP server or the SDKs. All four run on your machine, and profiles never leave it.
Create, start, and stop profiles from any language. Everything runs through a local API.
Connect ShardBrowser to Claude Desktop, Cursor, and other MCP clients to orchestrate profiles with natural language.
Python, Node, and Rust libraries that ship the browser engine. Built for scrapers, CI pipelines, and servers.
Browse the SDKs$ pip install shardx$ npm i @proxyshard/shardx$ cargo add shardxReady-made fingerprints from real hardware, proxy traffic that matches the OS the profile claims, and tools for running many profiles at once.
See the full feature list on GitHub (opens in a new tab)220 ready-made browser fingerprints for Windows, macOS, Linux, and Android, delivered via CDN. Change the GPU and the editor automatically adjusts CPU, RAM, and platform version to keep the profile consistent.
ShardBrowser provides full SOCKS5 UDP support and active p0f TCP fingerprint spoofing. This makes the OS fingerprint from your proxy match the TCP handshake that anti-fraud systems see.
Run a group of profiles as if they were one. Click, type, scroll, or open a tab in any window, and every other window in the group does the same thing right away. Each window still moves the mouse in its own way, so the sessions don't look like copies of each other. You don't pick a leader either. Whichever window you're working in is the one driving.
Build workflows from simple steps: open a page, click, type, wait, send a request, query a database. Then run them across as many profiles as you want, all at once.
Works with SOCKS5, HTTP, and HTTPS. Import proxies in bulk and test each one on the spot for connectivity, UDP support, and location. ShardBrowser then sets the profile's timezone, language, and geolocation to match the country the proxy exits from, so you don't have to.
Clicks and keystrokes, whether yours or a project's, come from the browser's own input path instead of DOM events a script dispatched. The pointer accelerates, overshoots and settles on the target, and text arrives one key at a time with an uneven rhythm and the odd corrected typo. To the site, it looks like someone at a mouse and keyboard.

Our product comes with the most advanced tools. And you get unlimited profiles.
The whole feature set is free and MIT licensed, so you pay nothing for it.
Profiles, cookies and fingerprints are stored locally. The API binds to 127.0.0.1 only. The launcher is open source under the MIT license, so you can read every line before you trust it.

Public browser checkers such as fingerprint.com, pixelscan.net, browserscan.net, deviceandbrowserinfo.com and antcpt test only part of the browser fingerprint. An anti-detect browser can pass these checks while still exposing inconsistent values on surfaces that are not tested there.
