PubNub Platform

PubNub Platform provides globally distributed infrastructure and APIs for building, managing, and optimizing real-time interactive applications. It includes publish/subscribe messaging, presence, data storage and synchronization, serverless message processing, access control, analytics, and integrations. Its services support channel-based messaging, message history and catch-up, structured data synchronization, event processing, and routing data to external systems. PubNub operates the underlying network, routing messages between devices and services with average worldwide delivery under 100 milliseconds and a 99.999% uptime SLA. Developers can build across web, mobile, gaming, IoT, and server platforms using SDKs and REST APIs.

  Send messages between users, devices, and services through channels, with support for high-volume communication and interactive application features.
• Reach Users With Low-Latency Global Delivery
  Route messages through a global network designed for low-latency delivery, regional failover, and scalable service across locations.
• Resume Message Delivery After Interruptions
  Help clients recover from connectivity interruptions and retrieve historical messages, including activity they missed while offline.
• Store And Synchronize Application Data
  Keep message history, application metadata, structured data, and shared files available across connected clients, including after clients return from being offline.
• Control Access And Protect Data
  Manage client permissions for PubNub resources and protect data using documented encryption options and access controls.
• Track User And Device Activity
  Monitor presence and occupancy across channels and use custom state to support real-time application experiences.
• Process Events At The Network Edge
  Run event-driven logic within PubNub's network to transform or route messages and automate application behavior without managing function infrastructure.
• Build Across Platforms With SDKs And APIs
  Use SDKs and HTTP APIs to integrate PubNub capabilities into applications across a range of programming languages and platforms.
• Turn Live Data Into Actionable Decisions
  Review application activity through dashboards, identify trends, and use real-time rules and actions to respond to live data and user behavior.
• Connect PubNub Events To External Services
  Filter and forward real-time events to supported external systems and deliver mobile push notifications through supported providers.
• Monitor Activity And Moderate Messages
  Inspect live channel activity and apply moderation tools to review or filter messages in real time.

PubNub Chat

PubNub Chat provides Chat SDKs and hosted messaging infrastructure for adding real-time chat to applications. Developers can build public-channel, direct, and group conversations using features such as threads, mentions, reactions, typing indicators, presence, and read receipts. The offering also supports message history, push notifications, access controls, moderation, and chat management tools, while PubNub handles the underlying messaging infrastructure.

  Show message read status and unread channel counts, with an option to mark channels as read.
• React To And Pin Messages
  Give users ways to respond to messages with emoji and keep selected messages visible at the top of a channel.
• Organize Replies Into Threads
  Keep focused side conversations attached to a parent message and let users quote messages in their replies.
• Mention Users And Link Channels
  Help users address others directly and reference channels within chat messages.

Mobile Push Notifications

PubNub Mobile Push Notifications connects PubNub messaging with Apple Push Notification service (APNs) and Firebase Cloud Messaging (FCM) to deliver notifications to iOS and Android devices. Applications can associate device tokens with channel names so devices receive notifications when a message is published to a channel. Notifications can be triggered by events or state changes, and delivery can fall back from in-app messaging to mobile push when users are offline. PubNub manages the connection to push providers for authenticated delivery.

• Reach iOS And Android Devices
  Deliver mobile push notifications to users’ devices using the native push services APNs and FCM.
• Reach Users Across Delivery Modes
  Deliver alerts in-app when users are online or fall back to mobile push when they are offline.
• Route Alerts Through Channels
  Connect device tokens to channels so messages published to those channels can reach the associated devices as notifications.
• Trigger Timely User Alerts
  Use events or state changes to send timely notifications, including updates about jobs, orders, and operational exceptions.
• Deliver Alerts At Scale
  Support notification delivery across a global service designed to handle traffic at scale and provide low-latency delivery.
• Simplify Provider Connectivity
  Rely on PubNub to manage its connection to APNs and FCM for authenticated push delivery.

BizOps Workspace

BizOps Workspace is a no-code set of tools in the PubNub Admin Portal for managing and monitoring PubNub applications in real time. Operations and support teams can view and update users, devices, channels, and memberships, while moderators can monitor conversations, edit or remove messages, mute or ban users, and send moderator messages. Powered by App Context, it provides a way to search, view, and update application metadata without building custom admin tools. When used with PubNub’s Chat SDK, it also supports watching users and viewing and replying to threads.

• Manage Apps Without Writing Code
  Give operations, support, and moderation teams direct access to application management tools in the Admin Portal without requiring separate custom tools.
• Monitor Live Messages And Activity
  Give teams visibility into live message flow and user activity so they can review conversations, investigate issues, and monitor application behavior.
• Moderate Messages And Users
  Help moderators manage conversations by changing or removing messages, muting or banning users, and sending moderator messages.
• Find And Update Users And Devices
  Help teams locate users or devices, review their information, and make updates through the workspace.
• Manage Channels And Memberships
  Let teams find channels, update channel information, and review or change channel membership through the no-code workspace.
• Update App Metadata In Real Time
  Manage application objects through a no-code interface. App Context emits real-time events when values change, so applications can respond to updated user, device, channel, or membership data.

PubNub MCP Server

The PubNub MCP Server connects MCP-compatible AI coding agents to PubNub documentation, SDK references, account context, and live API tools. Agents can retrieve current implementation guidance, work with PubNub account keys, and exercise core API methods while building real-time features. It supports hosted workflows as well as Docker and npx options, and works with tools including Claude, Cursor, Windsurf, Visual Studio Code, and other MCP-compatible clients.
