BeWelcome was founded in early 2007 and is grouped in the non-profit BeVolunteer organization. It is based on the free and open source BW Rox. BeWelcome is a website run by BeVolunteer, a non-profit association legally registered in Rennes, France. Members of BeWelcome do not have to be members of BeVolunteer. BeWelcome is similar to the Couchsurfing community, but free to use, add free, run by volunteers and has all the same main features. All features of the website and stays are free (a must). Travelers can contact each other via the website with accommodation requests and leave references for each other after they meet. The website also includes a forum, contacts management, map search, and allows for set up of events. t also has a TRIPS feature, which allows you to post your travel itinerary and dates, so that hosts can see your plan and offer accommodation.

BeWelcome has also been translated into other languages to make finding a host easier. The website is financed by donations of approximately €1,000 per year and has annual operating expenses of around €700 per year. As of September 2021, the platform has 215,000 members.

Trustroots is the new kid in town. It was launched in December 2014 targeting hitchhikers and other more alternative niche groups, though it's open to everyone. As of November 2018 you can only search by map, and the website is very usable on mobile phones, and there's an app for Android. The software is open source and the network is run by a UK non-profit foundation. It is comparable to BeWelcome with a nicer website but might not work everywhere. It is best to register with both and just choose the right one depending on the region.

Warmshowers is an online hospitality exchange organization exclusively for touring bicyclists that want either indoor accommodation or just a break from cycling and a warm shower.

In case you are planning to hitchhike, it can be a good option to bring a foldable bicycle along to bike part of the journey and take advantage of Warmshowers. This community is very welcoming but a little closed to no-bicycle outsiders.

Couchsurfing was once easily the largest free hospitality exchange platform, with both a website and mobile app. Though, it now charges a monthly (US$3) or annual fee (US$15) for access (with exceptions for users from lower-income countries). Therefore, many users have left for BeWelcome or Trustroots. The site's gradual commercialization has been controversial among its members, many of whom originally volunteered to help build the site under the understanding that it was strictly not-for-profit.

Global Freeloaders is based on the concept of getting a free place to stay and "seeing the world from a local's perspective". It predates CouchSurfing, having been founded in 2001, but has much fewer users. Members do not send individual requests for accommodation; they blast a request to several hosts at once. According to the website, one should only register if planning to host within the next 6 month, in an attempt to guarantee an active host community. In reality however this fact is not validated. One thing that distinguishes Global Freeloaders from similar networks is that it specifically asks members to host just as often as they are hosted by others.

Servas was created in 1949 by Bob Luitweiler, an American who lived in Denmark. Servas recommends that guest apply at least 4 weeks in advance of travel. Participation in Servas requires 2 letters of reference and paying a membership fee, which varies by country, and a personal interview with a local Servas coordinator. After the interview, the traveler gets a "letter of introduction" that's good for one year of travel, and a list of hosts in the countries he or she is visiting. Travellers contact prospective hosts in advance (lead time varies as defined by each host), giving estimated dates of travel, and they may be asked to reconfirm one or two days in advance of visit. They can stay with hosts for up to 3 days and 2 nights. Hosts provide sleeping space. Meals may be provided as well as assistance in visiting the city or area. At the end of their trip, Servas travellers are expected to provide a report to the local coordinator with any information that may be useful.

Google Maps is actually a map application but supports searching and finding countless hospitality places. The advantage of using Google Maps is that for many places you will find direct contact information like a website, email address or a phone number (for WhatsApp). If you use Google, you are potentially tracked and exposed to commercials, but direct contact to a hospitality place makes things much more personal and should be less expensive in general. And like Booking.com and Airbnb, places are often rated and reviewed on Google Maps.

Booking.com is mainly a hotel reservation website for commercial purposes. However, it also offers many listings of private people, like vacation rentals, apartments, guest houses, and BnBs. Especially in remote regions, it can be of advantage over other websites offering similar places. Often places are listed on several places concurrently, like hostels on Booking.com but also on Airbnb, or private apartments on Airbnb but also on Booking.com.

Airbnb was founded after two San Francisco locals rented out their airbed during a conference that made it hard to find accommodation. The service enables members to rent out their spare house, apartment, room(s), or couch in exchange for monetary compensation. Members can read reviews left for other members and their accommodation. Accommodation can be searched for based on several parameters including specific neighborhoods, privacy, and price. The amount of interaction between the host and the guest varies: in some cases the host will spend a lot of time with their guests and in other cases, they will never meet at all. Airbnb collects service fees from both the host and the guest from every booking. If the guest damages the property of the host, the host may be eligible for reimbursement from Airbnb under its $1,000,000 guarantee. Many hotels, hostels and guesthouses use Airbnb, which makes it harder to distinguish between a "real" host and a hospitality business entity.
