chromedp vs scanmem

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.

scanmem is a free, open-source interactive debugging utility for finding and changing variable values in an executing process. It searches a process by PID and uses values observed over successive scans to narrow the possible memory addresses. The command-line tool can search for exact values, compare changed or unchanged values, find increases or decreases, take snapshots, and search strings when configured for string scans. It can monitor matches as their values change and set values for selected matches or all known matches. GameConqueror provides a graphical front end with a process finder, flexible search syntax, variable locking, and a memory browser and editor; users can choose search regions and types. The project separates the command-line frontend from libscanmem, which performs the scanning. The project describes scanmem as a Linux utility and documents an Android build using a standalone Android NDK toolchain. Linux interactive commands require libreadline and a mounted /proc filesystem, while the GUI has additional dependencies. The default scan data type is int, though the option command can change it. scanmem is GPLv3; libscanmem is LGPLv3.
