Are there popular project sales exchanges?

Question

Business Informatics

If sites selling 3D models, is there something similar for it-projects?
I have a self-written web application, source codes, tests, simple documentation, it was not promoted or hosted anywhere. There are a couple of desktop Windows applications that I don't need (honed my coding skills), but I wouldn't mind selling them.
Are there similar exchanges where you can look at prices and post your offers?
PS: if they exist and you have had experience selling them, it would be very interesting to read.
