The other answers address the tool itself. Let me address the real value.
In my experience, any piece of software loses value extremely quickly. To retain value, it needs constant updating.
Thus, the tools I have developed lost their value very quickly. The main value I got out of them is the skill in developing such tools. That is a very valuable skill that ...
I have no idea how to value a piece of software like this.
