Note that chrome must be an alias of your Chromium executable ( see how to do this). In order to let Chromium use a custom proxy server, you can use the -proxy-server command-line option: chrome -proxy-server= If you want the web browser to use a proxy server that requires authentication, you’re out of luck. The addition of headless mode to Google Chromium and the launch of the corresponding Node.js API called Puppeteer by Google earlier this year has made it extremely simple for developers to automate actions on the web, such as filling in forms or saving screenshots of web pages. TL DR: During our work on Apify Proxy, we released a new open-source package called proxy-chain on NPM to enable running headless Chrome and Puppeteer over a proxy server that requires authentication.
