We use out product, JackDB[1], everyday both for analysis and to develop the product itself further. It's a database client entirely in your web browser and we use it to run queries to analyze stats, research database features, and just general querying.
If you have the luxury of working on a product you use yourself (anybody work on developer focused solutions probably falls in this category) then I highly recommend it. Daily use of a product shows you let's you really see what parts of our product are not quite "smooth".
Just don't go down that rabbit hole too far. The features you use and how you use them don't always align with everybody else. As an example, when we first got started with it, what we considered a "low barrier" for a new user to try it out was actually quite a leap. Seeing real users struggle with that let us solve it. In your own bubble you might not notice things like that.
