Is Localhost Open Graph Debugger safe?
Localhost Open Graph Debugger sends the active page's meta tags and preview images to og.nullnull.dev when you click Submit.
When you open the popup and click Submit, the extension reads meta tags from the current tab and sends them to og.nullnull.dev. If the page has Open Graph or Twitter preview image tags, it also fetches those image blobs and includes them in the same upload before opening the returned debug URL.
