What does hostless mean?
Hostless means without a host or central server. In computing, the term can describe software, a service, or a system whose functions do not depend on one dedicated remote host. Such systems may instead run on users' devices, distribute work across a network, or use resources in a serverless architecture. The word is more specialized than its simple English components suggest, so it is encountered mainly in technology, networking, and discussions of cloud or distributed computing. It should not be used as a general synonym for every system without a permanent physical server, since the precise arrangement varies by context. In ordinary writing, a phrase such as “without a host” is often clearer. Hostless nevertheless usefully highlights the architectural distinction between a centralized service and one whose components can operate independently across multiple devices or environments.
adjectiveWithout a host or host server; operating or occurring without being hosted on a central computer or server. In computing, it may also describe a system or application that runs on users' own devices rather than on a dedicated remote host.
- Without a host, host server, or other central hosting system.
- Of or relating to software or services that run without a dedicated server, often across users' own devices.
"The application uses a hostless architecture, with its main services running across users' devices."
"The team designed a hostless solution that allowed the application to run directly on each participant's device."
"Because the update was hostless, no changes to the central server were required."
In computing, hostless technology shifts the backbone of an application from a remote server to the devices where its users already work.

Etymology of hostless
The word was formed in the 20th century from the noun “host” and the suffix “-less,” meaning “without.” “Host” in its computing sense developed from an older meaning of a person who receives guests, which in turn comes from Latin hospes, meaning “guest” or “host.” The same Latin source also underlies words such as “hotel,” “hostel,” “hospital,” and “hospitality.”

How hostless is actually used
The term is relatively uncommon in general English and is most often used in computing and networking contexts. It can describe a system that has no central host or, more narrowly, software designed according to a serverless or distributed architecture. The sense is technical rather than ordinary.
Easily confused with hostless
A host is the computer or system that provides services or resources, whereas hostless describes something that does not depend on a central host.
