chromedp vs memwatch

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.

memwatch is a free, open-source macOS utility for searching and changing values in a running process’s memory through an interactive interface. Searches can target strings, floating-point numbers in 32- or 64-bit formats, and signed or unsigned integers from 8 to 64 bits. Comparisons such as equal, greater than, or less than can narrow results. Once values are found, memwatch can read, write, monitor, freeze, or unfreeze them. Its interface also has commands to pause and resume a target process and send it Unix signals, though execution-state support is described as experimental. The project presents memwatch as a macOS memory editor and says it should build and run on recent OS X versions. Its author describes using it for game cheats and as a debugging aid alongside tools such as gdb. Installation requires building from source with phosg and libamd64, then running make and sudo make install. Attaching to a target process uses sudo. The MIT License permits use without charge and supplies the software without warranty.
