Checking your OGP tags on developing environment, it usually not reachable from the Internet, was always too much hassle work :( We need to some proxy services like ngrok or need to just release it to internet. This extension is maybe BEST alternative solution for these works. It works well too for unreachable pages like under basic auth, etc.
