Party Evite

Hello, I'm hosting a birthday party and would like to self host my Evite if possible. I'm looking for the possibility of having dedicated links to send to each guest. The link will take them to a website where they fill in a form if they will attend and if the have any allergies and +1s etc. Would also be nice if they could see what other guests are attending. I have little to no experience with cloud flare tunnels but I guess that's where I should be looking? And then host some kind of RSVP service? I understand that this is so much easier with just a google form or whatever but where is the fun in that? 😄 Any tips?
