Chromatic is a Chromium runtime modifier and JavaScript engine injector designed to alter the low-level operational characteristics of Chromium and its embedded V8 engine. It functions as a tool for injecting custom logic into the V8 JavaScript engine to change application behavior at runtime.
The project provides mechanisms for browser engine instrumentation and V8 runtime manipulation. It enables the modification of the internal execution flow of JavaScript within Chromium-based environments to extend native browser capabilities or bypass standard limitations.
