Where to place a demo of your project for a portfolio?

Question

Network administration

I made a demo site, like for a portfolio, I want to put it on free hosting, anyway. Why fries? What would lay out and forget, just throwing a link to everyone. I try 000webhost.com/ but they get a 500 error no matter how I try to set up .htaccess in public_html.
Who posts their demos where? Please tell me where can I?
Without requirements in the video of the phone, symbolic payment and other things like that up to passport data. You need to post a short demo, for a couple of days and then you can delete it, it's like temporary mail, because they don't require a full name and a phone number.
Ideally, with the ability to host Symfony, because some go strictly for CMS or are sharpened.
