Do you guys notice that products which helps developers, engineers are mostly getting more upvotes?

Interesting observation, i never payed attention to it but now that you said this i do agree with you.

Maybe because these are developed by a large team.

I hadn't seen that but it is interesting! Perhaps many developers are here trying to find tools made for them. A main problem with many products is that they market themselves "for developers" but quickly stray away in order to capture a larger market share e.g. no-code. Devs are continuously looking for new tools, are curious in nature and ultimately open to trying new tools!
