Trevolin

Trevolin is a web app to find a like-minded travel buddy for your next travel.

Also you can find local travel guides to show you around new places. If you sign up as a travel guide, you can even make extra income by showing your city to other travellers.

Also you can find free accommodation by travel exchange, working holidays and volunteering programmes. You can join as a host if you can provide accommodation to fellow travellers.
