Browser required (e.g. Chrome, Firefox, Edge, Opera, Brave).
While the official NopeCHA extension is undetectable, it is important to choose the right extension host to avoid detection. Popular browser automation tools (e.g., Selenium, Puppeteer, or Playwright) are easily detected by CAPTCHA providers and websites. We recommend using a patched browser automation tool (e.g., nodriver) or a standard browser with automation performed either at the OS level (e.g., using PyAutoGUI) or from within the browser itself (e.g., via a custom extension or userscript).
If you need to automatically apply a custom extension setting for each new browser profile (e.g., automatically setting your API key), you can refer to the Extension for Experts guide to pre-configure the extension so that it is ready to use without manual configuration.
