i look up reviews and rating on alternativeto.net , search it on openhub and sometimes add projects i might be interested it (openhub reports development activity). i sometimes search for reddit for what people say about it.
There are a bunch of websites for user reviews, but honestly i haven't used them really iirc.
Honestly, popularity. If lots of other people use it, chance are somebody did that sort of check already.
As a heuristic, I look at the commit dates to see if it's still being maintained. And lately I look at the commits themselves for evidence of AI use. Then I'll maybe do a web search for discussions to see what other people/the community has to say about it.
~~Gnuhealth looks like it may be dead (or at least the repo I found hasn't had a commit in many years).~~ (Nvm, they moved to codeberg which is a positive signal, IMO).
Yah I follow a similar approach in addition to doing a simple search for well known malicious commands like rm -rf / and some others as well.
To add to what the other commenters are saying, I also sometimes look at whos responsible for the software. Is it a repo from a big company? Is it a gnu project? Is it just from somebody with a username consisting entirely of numbers? Is it hosted on codeberg or forgejo or some other friendlier server? That stuff also says alot, even if there are few recent commits, if its from reputable people you may still get well maintained software.
And also gnu health is a very important piece of software that is currently being used in a lot of african hospitals.
test it until something breaks, open a bug report and look at the reaction
Just to add what others are saying. Commit dates, see how many maintainers/contributors it has, recent PR, recent open issues, how developers respond to them, visiting their discussion forums. Checking their social media accounts can also be useful, might tell you how they interact with the rest of the community.
I look at the number of (hopefully recent) committers and whether they're human or not.
