One young person runs away every six minutes because of problems at home or school and loads end up sleeping rough on the streets.
Many think it's the only way they can escape their problems.
But that can be very dangerous because they can get into trouble on the streets.
The website, run by a project called Astra (Alternative Solutions to Running Away), gives support to people who have run away.
And if they have left home thinking they can escape problems, the website will help find organisations to sort them out properly.
