Each presence is a small record attached to a user, with a status string and optional metadata, and it broadcasts every change over a dedicated Realtime channel. It is built for online indicators, collaboration cursors, typing dots, and live attendee lists, the kind of UI signals that should disappear automatically when a user goes offline." + - question: "How is Presence different from storing status in a database row?" + answer: "A database row stays around until you delete it. Presence records expire automatically based on an expiresAt timestamp you control, so a stale online indicator never gets stuck after a user closes the tab or loses connection. Presence also ships with its own Realtime channels, so you do not need to write subscription logic or maintenance jobs on top of a regular table to get a live who-is-here view." + - question: "How long does a presence record live?" + answer: "Every presence carries an expiresAt timestamp, up to 30 days in the future. Once that timestamp passes, Appwrite deletes the record and emits a delete event on the presence channels. The typical pattern is to upsert the same presence on a heartbeat (every few seconds, or on focus and route change events) so the expiry keeps sliding forward while the user is active." + - question: "Who can read a presence record?" + answer: "Presences use the same permissions system as the rest of Appwrite. Set Role.users() for any signed-in user, Role.team('TEAM_ID') for a single team, or Role.user('USER_ID') for a one-to-one channel. Realtime subscriptions honor these rules, so a client only receives updates for presences it could have fetched with a direct GET." + - question: "Which SDKs support the Presence API?" + answer: "Presence is exposed through every Appwrite SDK as a Presences service, alongside Account, TablesDB, Storage, and the rest. Client SDKs (Web, Flutter, Apple, Android, React Native) can upsert and subscribe to presence directly from the user's session, and server SDKs can manage presence with an API key that holds the presences.read and presences.write scopes." + - question: "Do I need to run my own cleanup job for stale presences?" + answer: "No. Appwrite runs a background worker that removes expired presences automatically and emits delete events, so stale online indicators disappear without any extra code on your side. You only need to call delete explicitly when you want a user to go offline immediately, for example on sign out." +--- + +Realtime apps almost always need to answer one question that has nothing to do with the data they store: **who is here right now?** Whether it is the green dot next to a teammate's avatar, the cursor on a shared document, or the "typing..." indicator under a chat input, that signal is short-lived, frequently updated, and supposed to disappear the moment a user closes the tab. + +Building that with a database row works until it doesn't. A stale "online" flag survives a network drop. A presence table needs a cleanup job. A subscription has to know which row is whose.
