In their own words
chromedp
chromedp is a Go package for driving browsers that support the Chrome DevTools Protocol without an external driver. It runs Chrome headlessly by default and supports actions such as navigating, clicking, reading page text, running JavaScript, filling forms, and waiting for elements. Its examples also cover cookies, HTTP headers, proxy authentication, request interception, session restoration, and HAR recording. For output, it can capture screenshots, print pages to PDF, and save screencast frames as JPEG files. Separate browser contexts can support parallel work, but sharing one context between goroutines can cause races. A separate remote module connects to an already-running browser over WebSocket, and the project provides a headless-shell Docker image. By default, Chrome communicates over remote-debugging pipes and does not open a debugging port; switching to WebSocket uses one. The package is available under the MIT license at free. The README requires Go 1.27 or newer.
