When?

I’ve been building something for a while now, mainly for my own use, and I’m using it daily.
It works, but I keep feeling like it’s not “ready enough” yet.
There are always small things to fix, improve, rethink… and it’s hard to know when to stop and just put it in front of people.
For those who’ve been through this:
When did you decide it was time to let real users in?
Was it when everything felt stable?
Or did you just go for it earlier and learn from there?
