Could you help me find this website?(Details inside)

Hello everyone, it’s been a while since I posted my last question, so here’s the thing, I remember having seen this website about a year ago, it’s kinda like a intermediary-website for hosts that provide a place to stay and maybe some foods, and visitors who would like to help them do some chores, like some farm work, boat maintenance, babysitting/taking care of old people, etc. The period can vary from a few days to some weeks, even a month or two. It’s like a working-while-travelling thing.
My question is, can you help me find this website if possible? I think the name is three words, something like “travellers and hosts”, and one can register as one of them, I registered as travellers and found information of hosts all around the world.
P.s., and are there many websites like this one?
My grammar is not very decent so thank you for all your attention and time! :)
