chromedp vs ProMod

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.

ProMod manages memory modifications for individual processes on macOS and iOS. On a Mac, it writes four-byte ARM instructions into a target process and automatically uses code caving for larger patches. Special mods can follow an address in a CPU register and monitor or rewrite float or int32 values when thresholds are met. One-instruction mods can use hardware breakpoints without writing to the target app’s memory; the FAQ says a Mac processor allows six at a time. Keyboard shortcuts can trigger one or several mods, with audible cues. Setups can be saved and shared as portable .pro files, with built-in or password encryption. Bytes Diff scans for memory changes, and Memory Locator searches for hex patterns. Users can enter raw hex or ARM64 assembly, which ProMod assembles, and disassemble surrounding instructions. The Mac app requires an Apple Silicon Mac with macOS 12.0 or later; Intel Macs are unsupported. ProMod Mobile runs on non-jailbroken iOS devices but requires injecting libProModMobile.dylib with Sideloadly or a similar tool. The maker describes it for debugging, learning, single-player, and offline use.
