The main use case for the product is bug reporting. When a user encounters an issue with a website (or other product) they can navigate to this web page and screen capture the issue in a more meaningful way to help product developers identify and fix the problem.<p>tl;dr: It Works On My Machine (specifically Chrome running on MacBook Pro M2). There needs to be a lot more work done to get the page working on desktop Firefox/Safari browsers. Support to get the page working on mobile browsers is out-of-scope for this side project.<p>Also tl;dr: Built in vanilla HTML, CSS and Javascript. No frameworks. No toolchains or build steps. All functionality is client-side: no sign-in or registration required. No added tracking. Page can be self hosted and/or downloaded and run locally. YMMV. Enjoy!
