You can focus on launching innovative features instead of managing complex infrastructure. Our platform lets you build, deliver, and manage real-time experiences across web apps, mobile apps, and IoT devices. Whether you are creating in-app chat, live audience engagement, operational dashboards, IoT coordination, AI-driven interactions, or any other real-time functionality, PubNub brings it to life with a suite of purpose-built APIs, SDKs, Solution Kits, integrations, and analytics. What makes us different? ~Scalability~ PubNub is the industry’s most scalable platform that allows for rapid concurrent usage without financial penalties. Because we allow for an unlimited number of concurrent users, you’ll never have to worry about exponential cost increases due to growth. \* Handles over 800 million active devices and over 3 trillion API calls delivered monthly. \* Record for the largest online concurrent event with more than 10.5 million users \* One connected fitness client stated, “From testing to 1,500 rides a day today, to an estimated 15,000 rides a day in the coming months, we’re confident PubNub can handle that growth.” \* "When we hit our concurrency limit [with our previous provider], it was a no-brainer to go with PubNub to power our entire platform and our whole team gave the go-ahead. We knew we would be supported by PubNub no matter how many users and messages we were handling.” Virtual Events Company ~Reliability~ With low latency and high uptime, PubNub users can trust in and rely on a true real-time digital experience that leads to authentic and engaging interactions for their audiences. \* 99.999% uptime Service Level Agreement and global points of presence with automatic routing for failover and redundancy. \* Every message delivered to any device in milliseconds \* Multi-region replication, redundancy within and across data centers, geographic server distribution, geo-routing, and latency monitoring. ~Security and Compliance~ While powering real-time engagement is our passion, security is our priority. We deliver enterprise-grade security, end-to-end encryption for every message running over the network, fine-grained access controls, localized data storage, and more. \* PubNub is ISO 2700, SOC 2 Type II, GDPR, and HIPAA compliant and we conduct annual SOC and ISO audits along with annual penetration testing conducted by third parties. \* A leading healthcare software solution provider stated “data security and HIPAA compliance are extremely important … When we evaluated PubNub as a real-time messaging service, we were very impressed by how easy they were to use. We were sold on PubNub as a partner once we learned about their strengths in data security, SOC 2, and HIPAA compliance.” ~Flexibility~ PubNub is a platform solution that enables teams to build the real-time experiences users demand and leaves the door open for adding additional features and functionality in the future. \* We have developed over 50+SDKs and over 65 pre-built integrations with external and third-party APIs, PubNub gives developers the features they need regardless of programming language or tech stack. \* A food delivery service customer reduced ticket resolution times from five minutes to 30 seconds and stated that “having that flexibility in building and being able to have our chat operate in real-time was key to us—that’s why we chose PubNub.” ~Support~ As a trusted extension of your ops team, PubNub is a partner from design through testing, launch, and beyond. With our white glove support and features like 24/7 support across the globe, a robust self-service library, and operational dashboards, ensuring your app is supported at any level, throughout its lifecycle. \* One PubNub client went from having a dedicated programmer spend 75% of their time monitoring their in-house chat to effortlessly scaling their chat to support 40x growth within a year. \* Partnering with PubNub allowed one virtual events customer to bring their users together in ways not previously possible, “With PubNub and their live event support team, we are able to truly scale our chat to a large number of concurrent users at a time, and that’s what enables us to bring that interactivity between a creator and their fanbase.” \* A rideshare customer was able to focus on building their app because "powering real-time updates and signaling is not our domain. Using PubNub lets us focus on our expertise.” ## PubNub Pros & Cons **What users like:** - Users appreciate the **secure chat functionality** of PubNub, enhancing their interactive communication with real-time capabilities.

Saved Us Countless Dev Weeks on Server-Push Solutions **Rating:** 4.0/5.0 stars **Reviewed by:** Greg G. | Principal Software Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** June 29, 2026 **What do you like best about PubNub?** Saved our teams countless dev weeks in building custom server-push solutions across the enterprise **What do you dislike about PubNub?** Our main frustrations have been recurring, unexplained reliability issues — presence-related timeouts and 500 errors that have repeatedly hit our production services with no change on our end, usually requiring us to reach out and confirm the problem was on PubNub's side rather than being proactively notified. This is made worse by limited observability: the status page reports latency but not availability, and we lack self-service access to API and presence logs, so investigating an incident means manually requesting log exports and waiting. Usage and billing visibility is also weaker than we'd like — it's been consistently hard to understand what drives our transaction volume, including how transactions are counted and why a meaningful share of our billed publish volume comes from presence events we don't even consume. **What problems is PubNub solving and how is that benefiting you?** PubNub powers the real-time messaging infrastructure behind our consumer-to-agent and consumer-to-consumer communication across several Zillow products. Rather than building and operating our own WebSocket and pub/sub infrastructure at scale, we rely on PubNub to deliver messages reliably and with low latency, manage channel subscriptions, and handle presence detection so we can show who's online and surface unread message counts. This lets our engineering teams focus on product features — chat experiences, co-shopper notifications, agent messaging — instead of the underlying real-time delivery layer, and it scales with our traffic without us having to manage that capacity ourselves. ### 2. Reliable Real-Time Communication with Some Limitations **Rating:** 4.5/5.0 stars **Reviewed by:** Sandeep G. | Engineering Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** June 24, 2026 **What do you like best about PubNub?** I find PubNub extremely reliable. It's been crucial for our education platform because we rely heavily on its functionality for live sync interaction, connecting teachers and students in real-time. The whole data transfer aspect works well, especially for live interactions like scribbling between teachers and students. Additionally, PubNub made it easy to get started, even if mastering all aspects required digging into the documentation. **What do you dislike about PubNub?** History fetching is limited. I mean, you can hardly fetch 50 messages in one round trip. If I have to get the entire history for my use case, for scribbling data, I need to make sequential calls to get the entire data. Sequential stage was not present in PubNub. The kind of features we have, like writing on the Canvas, if the sequential message doesn't come in order, then it looks odd, and the context gets lost. So we have to build a sequencing logic on top of it. **What problems is PubNub solving and how is that benefiting you?** PubNub enables real-time communication and data reflection between teachers and students on our online education platform. It supports live interactions and data transfer efficiently, making our synchronous activities smoother and more reliable. ### 3.
