BeWelcome is a hospitality exchange network that connects travelers who are looking for free accommodation with hosts who are willing to offer it. It is a free online community of people from all over the world who offer and find hospitality. On BeWelcome, travelers and hosts can share their culture, language, and knowledge with each other. BeWelcome allows travelers to search for hosts in their destination, read and write reviews, and contact hosts directly. Hosts can list their place, set their own terms and conditions, and filter potential guests. Members can also take part in forums, join local groups, and meet up with other travelers and hosts. BeWelcome is a great way for travelers to get to know the locals, save money on accommodation, and experience a destination from the perspective of a local. It is a great way for hosts to meet people from around the world, learn about different cultures, and share their hospitality.
Also open source and based on the work of volunteers.
