dechromium
Anti-detect browser built on Chromium. Manages browser profiles with isolated fingerprints — canvas, WebGL, audio, fonts, screen, navigator, timezone, and network. All spoofing is implemented in C++ inside the browser engine. No JavaScript injection, no CDP overrides.
Install
pip install dechromium
dechromium install
The first command installs the Python library. The second downloads the patched Chromium binary from GitHub Releases.
Quick start
from dechromium import Dechromium, Platform
with Dechromium() as dc:
profile = dc.create("my-profile", platform=Platform.WINDOWS)
browser = dc.start(profile.id)
print(browser.ws_endpoint) # connect with Playwright, Puppeteer, or Selenium
# browser automatically stopped on exit
