HelpxFree: All time  (20€ – 2 years membership)

Helpx is a work exchange network started back in 2001. The idea came from Rob Prince, who has traveled over several years throughout Australia and New Zealand. In order to keep travel longer, he started to work in farms and hostels for accommodation and, sometimes, food. Didn’t took longer to realize that it would be useful for both travelers and hosts if he put up an online database of hosts looking for help. It was born helpx!
