PubNub

Global infrastructure for real-time, interactive applications

Visit PubNub

PubNub is a cloud-based real-time communication platform that provides infrastructure and APIs for sending and receiving messages between devices, apps, and services. It uses a publish/subscribe model where clients publish to named channels and subscribe to the channels they care about, addressing the need for low-latency delivery, ordered messaging, catch-up after reconnections, and fan-out at scale without teams building and operating the underlying systems themselves.

The platform includes programmable pub/sub with channels, subscriptions, message actions, signals, message types, and channel groups, alongside presence detection, message persistence and data storage, analytics, and logic functions for interpreting and acting on messages. It offers 50+ SDKs for web, mobile, gaming, and IoT, plus integrations with push notifications, events, Kafka, and webhooks. Security features include end-to-end encryption and fine-grained access control, with SOC 2, SOC 3, HIPAA, GDPR, and CCPA compliance noted. The PubNub MCP Server and Skills support AI-assisted development, while PubNub Insights provides dashboards and PubNub Illuminate supports real-time experimentation and optimization. The global network spans multiple regions with region pinning and a 99.999% uptime SLA.

PubNub is aimed at product and engineering teams building interactive applications across sports and media, digital health, gaming, ecommerce, and transportation. The platform is available through a free plan and paid editions; contact Sales for details on packaging and availability.
