Witchcraft: JS/CSS injector

Witchcraft loads custom Javascript and CSS directly from a folder in your file system. Think GreaseMonkey for developers.

Witchcraft is a powerful Chrome extension designed for developers to easily inject custom JavaScript and CSS into web pages based on domain matching. Acting like Greasemonkey but optimized for developers, it loads scripts directly from a folder on your file system, matching based on the domain name hierarchy (e.g., loading gist.github.com.js when visiting gist.github.com).

Unique among scripting tools, Witchcraft auto-updates scripts immediately after edits without needing to reload the extension - just refresh the target page. It supports both JavaScript and CSS, runs cross-platform on Windows, MacOS, and Linux, and features directives like @include for loading additional files and options for custom server addresses. For seamless, real-time script management tailored to your web development workflow, Witchcraft is an indispensable tool.

I had trouble setting it up. I followed the instructions as best I could and then reached out to the developer with a descriptive inquiry, inclusive of images. No response. Nonetheless, I can't knock the app too much because of my technical limitations. If I could get it to work it would be significantly better than tampermonkey.

I can't believe I was using Tampermonkey for so long as this is clearly better by a longshot.
