Pendu is a free service for gamers combining voice parties, group calls, and chat. Drop-in party rooms support up to 50 people and include hosting and moderation features. Users choose a game, fill seats with friends, and begin immediately or schedule a later party. Group messaging supports text, reactions, voice notes, media, and replies from notifications. Voice and video calls start directly from group chats without meeting links or a waiting room. After a party, users can select teammates to play with again; mutual selections create a one-tap way to start another party together. Pendu displays trending games by day, week, and month. Messaging, calls, and party rooms work in a modern browser without installation, and the service describes desktop sessions as ready for use on a PC while gaming. Pendu is available on the web and Android. The site describes it as free to use and links to a Help Center, privacy information, terms, and child-safety resources.
