What is In-App Messaging? How It Differs from Push Notifications

Home > Blog > In-App Messaging vs. Push Choosing between in-app messaging, push notifications, and SMS is a critical decision for global user retention, yet many product teams mistakenly group them under the generic label of "notifications." While sending an alert seems simple, using the wrong channel at the wrong time is a primary driver of notification fatigue and user churn. This 2026 strategic guide breaks down in-app messaging vs. push notifications vs. SMS — technical and operat

Best PubNub Alternatives in 2026 for Social and Chat Apps

Home > Blog > Best PubNub Alternatives Finding the best PubNub alternatives in 2026 requires more than just swapping one messaging pipe for another. While PubNub is a powerhouse for raw data streaming, building a high-engagement social app on its infrastructure often means fighting the platform to add basic in-app chat SDK features like friend lists or community roles. Most developers looking for a PubNub alternative aren't just seeking reliability; they are looking for social-native

Video Call API & WebRTC Guide 2026: Choosing the Best Infrastructure for Scale

Home > Blog > Video Call API & WebRTC Guide A Video Call API is the managed infrastructure layer that abstracts the complexity of WebRTC, allowing developers to integrate high-quality signaling, routing, and media delivery without building a backend from scratch. In 2026, as raw WebRTC management becomes increasingly specialized, choosing the right infrastructure defines your product's reliability. At Nexconn, we've found that the shift from "owning the stack" to leveraging a high-per

Twilio Programmable Chat EOL: Best 2026 Alternatives

Home > Blog > Twilio Alternatives in 2026 Twilio built its business on carrier infrastructure. SMS, voice, programmable phone numbers — that's where the company made its name, and that's where its engineering depth genuinely lives. In-app chat arrived later, and the trajectory is worth understanding. Twilio launched Programmable Chat as a dedicated in-app chat API for developers building arbitrary applications. By 2022, it was officially deprecated — Twilio told existing users to migr

What is a Chat SDK? When to Use It Instead of a Chat API

Home > Blog > What is a Chat SDK A Chat API is a server-side interface — the contract between your backend and the messaging infrastructure. Authentication, message routing, offline queuing, push delivery, history storage. Your backend engineers work with it. End users never encounter it directly. Choosing the right integration path defines your product's ceiling. For a deep dive into how native social infrastructure handles 3,000+ concurrent members and "gift storms", explore the Azal

Sendbird Alternatives in 2026: Why Engineering Teams Are Moving On

Home > Blog > Sendbird Alternatives in 2026 Sendbird did something important: it made in-app chat accessible at a time when the alternative was building the entire stack from scratch. For a lot of teams, that mattered. For a lot of teams, it still does. The frustration that's driving migrations in 2026 isn't that Sendbird doesn't work. It's that the cost of working with it — the pricing structure, the engineering overhead, the gaps between documentation and actual SDK behavior — has s

Home > Blog > The Definitive Guide to In-App Messaging Building chat looks easy on a whiteboard. You send a string, they get a string. Simple, right? But then reality kicks in. You’re dealing with a user on a shaky 3G connection in a Jakarta basement where packets simply vanish. Then there’s the aggressive battery management on budget Android phones that kills your background process the second a user switches apps—all just to save a tiny bit of "juice." That "instant" message is now

Easily Add Chat to your iOS App with the Nexconn Swift Chat SDK

Home > Blog > Easily Add Chat to your iOS App In the current digital landscape, the cost of "context switching" has become a hidden hurdle for business growth. If a user has to jump out of your app to sort out a delivery or ask a quick question, your sales path is basically dead. It’s a total vibe killer. When they head to a different chat app, you aren't just losing their attention for a minute. You are actually giving away control of your data and your brand's value to a third party.
