Can this be used on a local development server to find broken image links?

Ok, I just watched the video. As a rule I avoid video!! I prefer to Read info, and will rarely click on any video links.
That said, I did take a chance this time: your video is actually quite well done.
Great Attention to detail. Clear highlighting of intent/task (via red marker).
It gives me a good impression of your plugin.

May I suggest adding some of this great info attention to detail to your About Page, and FAQ list? Maybe even some screenshots from the video?

Some of my questions were answered in the video:
1) (not answered), but I presume it DOES work on a local dev server.
(There are similar plugins available to do Not, hence the question.)

2 & 3) It looks like it does find broken internal links, and these will be found on a separate tab. This will include images, and other broken links.

4) Broken links (and hence broken images) can be edited from within this plugin’s dashboard.

This plugin looks great. I’ll be trying it soon.

A few questions:

1) Can this be used locally on my dev server?
Ans : no .. it only works on live server

2) Can this be used to find internal broken image links or missing images?
For example, if an auto-generated thumbnail size is referenced in a post/page/widget, that no longer exists in the uploads folder.

Ans: it only finds broken images

3) Can I filter results by internal or external links? Or by missing images?
No , you will have all broken links in a tab

4) Can I edit broken links directly from the results page of your plugin?
Yes You can
