What are you building right now? And how do you validate your idea?

Let’s support each other, drop your current project below and tell us how do you validate it

Here's mine: Currently building ProductRank, an app for sharing your SaaS and getting traffic on it, has a social feature so your followers get notified when you ship and analytics to track your performance.

The problem is that I'm not sure at all if the idea is valid, that's why I would like to know how do you validate your ideas, in my case I've seen many competitors doing similar products so I think that's a good point, also I'm getting some users in my waitlist so that's a good sign too, what do you think?
