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 value the **secure chat functionality** of PubNub, enhancing interactive communication and file sharing efficiently.

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. The ideal software for communication and integration with developer-friendly features **Rating:** 4.0/5.0 stars **Reviewed by:** Aman G. | Software Developer, Staffing and Recruiting, Mid-Market (51-1000 emp.) **Reviewed Date:** July 28, 2023 **What do you like best about PubNub?** Real-time spilling, gaming, and scrambled record sharing are all backed by PubNub. With the direction and back help that was continuously accessible to reply questions, the establishment was very basic to total. It is fabulous at creating amazingly tried and true information centers in expansion to being culminate for building real-time applications. Joining the SDK with one of a kind applications is truly straightforward. Hence, information sharing between cross-platform programs is straightforward. **What do you dislike about PubNub?** Giving caution of changes in development should be progressed. It is conceivable to boost the speed of infrastructure bolster. The bolster team isn't real-time, so utilize caution in the event that you're making a vital application and depending on them. Certainly the cost, which may rapidly sneak up on you. **What problems is PubNub solving and how is that benefiting you?** By expelling the real-time and notice administrations from the app, PubNub is endeavoring to address a developer's issue so that the engineer may concentrate on other key components of the app. Speedy communication and successful conveyance of framework prerequisites are colossally useful to the firm. This gives designers more time to concentrate on other components of advancement. makes work more beneficial. Being able to create applications in genuine time and execute them the way I need them to moves forward my execution at work. ### 3.

It has different SDKs for different languages, making it quite versatile. So cross-platform applications can exchange data easily. **What do you dislike about PubNub?** The support team is not real-time and if you are developing some critical application and vouching for the support team, then be careful. The documentation is not user-friendly as expected by beginners. **Recommendations to others considering PubNub:** Please read the documentation carefully as it is not easy to find everything in the documentation, and it takes a while for sure. Make a habit of using the console frequently as it will help to code quickly. **What problems is PubNub solving and how is that benefiting you?** We are developing a software which our internal team can use from their phone. Instead of an Android application that can be bulky, we are using web-based solution API and then have no chances to crash. - [View PubNub pricing details and edition comparison](https://www.g2.com/products/pubnub-pubnub/reviews?filters%5Bnps_score%5D%5B%5D=4§ion=pricing&secure%5Bexpires_at%5D=2026-08-14+03%3A51%3A14+-0500&secure%5Bsession_id%5D=7c61f02d-6649-4e34-9af1-52871c884573&secure%5Btoken%5D=76be77542d09bce9ccb05b70edbfd0c45d6e4325e34973c9bc623b81efd5a289&format=llm_user) ## PubNub Integrations -
