What it does

CloakBrowser is a stealth Chromium browser that evades bot detection, allowing developers to automate browsing without being flagged as a bot.

When to use it

•When scraping websites that have strict bot detection measures
•When automating tasks that require a browser to mimic human behavior
•When replacing Playwright with a more stealthy alternative

Ready-to-paste prompt

browser.get('https://example.com'); browser.find_element('css selector', '#login-button').click()

Heads up: Make sure to set the `CLOAK_BROWSER_BINARY` environment variable to the path of the CloakBrowser binary, as specified in the GitHub README
