Chat and messaging are critical components for application success. When searching for a provider to enable in-app messaging, you might compare Stream Chat with Sendbird. Sendbird is a highly funded, feature-rich chat application that is priced as if they are the only provider in the market. Stream Chat, however, provides an even richer complete messaging experience, bundling more advanced features out of the box.

Summary

  • Stream has years of experience building highly scalable, high-performing infrastructure powering chat along with activity and news feeds for over one billion end users.
  • Stream Chat has been proven to support 5 million concurrent users in a single channel, making Stream the preferred in-app chat provider for enterprise organizations hosting the world’s largest online events.
  • Stream Chat is the first and only messaging API/SDK solution available on global edge infrastructure for max performance across continents, with latency 5x lower than a traditional region-based cloud approach.
  • Stream’s solution is feature rich, providing capabilities like AI moderation, @mentions, banning/muting users, custom objects, threads, reaction, slash commands, and built-in search.
  • Stream provides an extensive portfolio of front end components and a set of beautiful UI kits to make integration more straightforward than any other product on the market.

High-Level Overview

Stream Chat is the most complete chat solution available. It supports five use cases out of the box, providing a beautiful UI kit for each in both light and dark modes. The UI kit can be handed off to your designer, and they’ll have all the assets at their fingertips, making it a breeze to swap out what they need to. The five use cases are:

  • Social Messenger
  • Livestream
  • Commerce
  • Team
  • Gaming

Selecting the use case will modify your chat settings for that usage — for example, the Livestream use case will turn off typing indicators and read status since the volume will be so high.

Built on top of Go, Raft, and RocksDB, Stream Chat leverages many of the same components our market-leading Activity Feed solution is built upon. Over the years our team has learned how to scale feeds to support billions of updates a month in real time, and we’ve used that experience to create one of the fastest and most scalable chat solutions possible. We are trusted by Hopin, IBM, BeachBody, Under Armour, Crunchbase, NBC Sports, Bandsintown, eToro and many others. We are GDPR compliant, HIPAA ready, EU and Swiss Privacy Shield complaint as well as CCPA.

Stream’s Strengths over Sendbird

  • Component libraries for React, React Native, Flutter, iOS and Android (Java, Kotlin, and the world’s first Jetpack Compose chat SDK).
  • Features: Reactions, Threads, Slash Commands, Rich Messaging, and support for chatbot integrations.
  • AI Moderation
  • Highly scalable, stable and high performing infrastructure
  • 2x to 4x more cost effective
  • Simple Migration

Front End Components

Stream provides component libraries for React, React Native, Flutter, iOS, and Android. This vastly reduces the time your team needs to spend building the chat frontend. Integrating with Stream typically takes days, whereas integration with Sendbird can take much longer if your existing tech stack isn’t supported. Stream’s component libraries are fully customizable so you are in control over your chat user experience.

Stream’s frontend components also include built-in support for unread counts, connection recovery, message states, and read events, among many other advanced features. (View a full list of Stream Chat SDK features for the frontend language of your choice.) Although it may be possible to achieve similar outcomes with Sendbird, Stream’s comprehensive component libraries are designed to save you time and hassle — one of the main reasons to develop your in-app chat on top of an API solution in the first place.

It should also be noted that Sendbird obfuscates their SDKs (JS, iOS, Android). What this means is if you’re trying to debug unexpected behavior, determine if you’re writing good code to the SDK, etc, your life just became much more difficult.

Premium Features

Out of the box, Stream provides advanced features for your one to one, group, or open channel messaging experiences. Features like slash commands, on-prem option, reactions, and threads. We also provide developers with a clean API and webhooks, allowing them to build custom features like chatbots, user polls, and anything else they dream up. Sendbird advertises built-in language translation capability, but they’re simply calling out to 3rd party services as we explain in our blog.

Messaging – Stream Chat vs. SendBird

AI Moderation

Stream provides admins the ability to mute and ban users, mute channels, and send system-wide notifications to help keep your conversations civil. Our tools allow you to ensure user safety within your app. Activating our AI based moderation will automatically protect your users from spam, profanity, and explicit content. We even have a partner that can take your AI moderation to the next level, detecting advanced concepts like self-harm, grooming and many others.

Sendbird doesn’t provide any AI moderation.

Highly Scalable, Stable and High Performing Infrastructure

Stream Chat is built upon the same Go, Raft, and RocksDB infrastructure that powers the activity and notification feeds for over one billion end users. With the ability to support more than 5 million concurrent connections for a single chat channel, Stream’s ability to scale is second to none.

Scalability & Performance – Stream Chat vs. SendBird

Stream’s infrastructure has had 99.99% uptime over the past 12 months, showcasing the kind of stability customers can rely on. We’re confident enough in our uptime that we offer a 99.999% uptime SLA to enterprise customers.

Enterprise Features – Stream Chat vs. SendBird

From proposals we’ve received from customers, Sendbird is between 2x and 4x higher on price than Stream. This increase doesn’t even account for the fact that Sendbird isn’t multi-tenant. Their pricing is based per app.

Simple Migration

Stream can work with you to make your migration a snap. With our import tools and customizable interfaces, we can help get you off Sendbird and into Stream Chat in no time. Companies have been switching to Stream because of our:

  • Scalability
  • Performance
  • Stability
  • Advanced Features
  • Customer Support
