I was doing software development in the past with my own company. I no longer have that company.
However, I published some small utilities which were especially made for SR, because I thought there's no good solution available yet. These tools were hosted on the server of the company.
While the domain still exists, the links are broken. Sometimes people inform me about it, which is fine. However, it will take some time to make the tool open source and in the meanwhile people need to wait.
How would I proactively find answers of myself which have a broken link? Thus I could go through these and make the code open source before someone finds out that the link is broken.
