inviter

An inviter is a person or entity that extends invitations to others to attend an event, join a group, or participate in a service. In everyday language, the inviter is typically the host or organizer who invites guests, sets the date, and communicates details. The term also applies to systems or software components that generate and send invitations, such as a feature in online platforms that allows existing users to invite others to join a network or workspace.

In social contexts, inviters may specify RSVP requirements, capacity limits, and invitation exclusivity. The inviter’s relationship to invitees can affect access or perceived formality, with hosts, sponsors, or designated organizers playing that role.

In digital contexts, an inviter may issue invitation links or codes, control expiration, and track invitations for onboarding or referral programs. Invitation systems are common in private communities, collaborative tools, and some games, where membership is restricted to those who receive a valid invitation.

Etymology and related terms: the word inviter derives from invite plus the agent suffix -er. The counterpart is invitee, the person who receives the invitation. Related terms include invitation, invite link, invitation-only, and referral.
