Our house was exactly the same when my son was younger - always the hang-out place!
We seemed to go through a prolonged period of pre-teens constantly lolling about the house & garden, eating & drinking everything in sight, etc. Our son would tell us that their parents wouldn't allow them to go to theirs, instead, whenever I queried it.
It got to a point where it was really getting on my nerves, so I came up with a set of ground rules & decided to just embrace the situation! Things like no noise out in the garden after a certain time, shoes off in the house, which rooms/bathroom they could use, specific snacks & drinks (cheap stuff!) that were put aside just for them, no bad language on the garden (little kids next door), tidying up ALL their mess, everyone leave by a certain time, etc. There were obviously days when no-one was around & I insisted on breaks every now & then, which they always stuck to - I made it clear that if they couldn't follow the rules, our 'youth club' would be firmly & permanently closed!!
I had to get over the irritation about other parents not doing the same & just figured that if we stopped it too, our son would have a much less fun social life! 🤷♀️
Our son & all of his mates were actually really respectful & grateful and on many occasions we overheard the other lads saying how lucky our son was & how much they appreciated a place to hang-out. It was good to know they were safe at ours, rather than roaming the streets, bored.
Over the years, we've ended up being the 'safe place' that his mates know they can come to & we've opened the door many times to both boys & girls that have lost their phones, keys, lift home, fallen out with boyfriends/girlfriends/family, etc.
Our son is 18 now & about to go off to Uni & I can't tell you how much I miss those days. All of his friends still talk to us & I've had several bunches of 'thank you' flowers over the years. Our son only said the other day how much he really appreciated all of it - in fact, his mates are meeting round at ours one night next week before they go for a night out, so that they can say hello.
