I have software that creates websites in the same design very quickly. For a project, that required many websites of the same layout and design (rather, the design didn't really matter too much). They were in different topics and the content is original in each. Many aspects of each site were generated automatically, or with only a little input.
The project is coming to an end and so the software is not really required any more. There is years of work in it and I do not want to miss an opportunity to put it to some other use.
I have been trying to come up with an idea as to what the software could be used for next. The software could be adapted, but would not be easy to improve to a point where it could be sold. Basically, it just builds sites and is probably not unique and good enough for sale. Currently difficult to learn to use/ bad GUI... It did the job required but not a pretty thing.
In short, I think I am asking:- What online needs lots of populated html pages or multiple sites?
They will sell for tiny amounts; if you want to break out of that you need to consider ways you can add value to each site you've built. The value that buyers see is in a established site with a proven income stream.
