Smooch Embeddables: The next generation of Messaging SDKs

Today, as part of our SaaS pricing plans, we're making our iOS, Android and Web SDKs available to software makers for distribution under their own brand.

This offer coincides with the general availability of new versions for each of our SDKs. This release has been developed specifically with the high performance and scalability needs of leading software companies in mind: Web Messenger 4.0, Android SDK 5.0 and iOS SDK 6.0. Our new SDKs are powered by a set of optimized backend APIs that we have progressively deployed to production over the last few weeks.

SDKs for Distribution

Introducing our SDKs as an OEM component completes the package for software makers. They'll now be able to offer the full spectrum of messaging channels that the businesses they power need to engage with a diversified customer base.

Smooch Embeddables

This new capability allows you to distribute web and in-app messaging SDKs under your own brand to your customers, so that you can build software that provides access to these channels using our API.

Our brandable offering equips you with ready-to-distribute builds of our SDKs that are rebranded at the code level to cover the full SDK API. For example, instead of Smooch.init() your SDK will be initialized with YourBrand.init(). This way Smooch truly lies under the hood. As always, the conversation UI remains fully customizable by each app or website that embeds it.

With the package, you also receive documentation covering everything you need to know about distributing an iOS, Android and Web SDK for your customers, along with the details on what they need to integrate into their apps and websites.

If you've opted for our Enterprise pricing plan, you’ll also get access to the full source code of our 3 SDKs via your own private Github repository.

Performance, Performance, Performance

This major iteration to our SDKs has been focused on these ‘under the hood’ changes. The core of all 3 SDKs has been refactored using a new, highly optimized initialization sequence. We have fully redesigned how each SDK interacts with the Smooch platform, and when key events like creating an appUser or establishing a WebSocket connection should be happening.

These optimizations result in a faster SDK initialization. For example, compared to the Smooch iOS SDK 5.x, our init sequence on 6.0 is twice as fast!

Overall, these deep changes deliver significantly reduced usage of the CPU and networking resources, ultimately resulting in better battery life for the end-user. On the backend side, it sets our platform on a growth and scalability path upon which we can build for many years to come.

Other Improvements in Web Messenger 4.0

Web Messenger is also getting its own set of improvements with this release. The biggest change is that Web Messenger now renders itself in an <iframe>. This delivers the following key benefits:

  • Web Messenger gets its own JavaScript runtime, making it compatible with 100% of websites and Javascript frameworks (and we know there’s more than a few 😝 ).
  • Web Messenger gets its own CSS context, making head-scratching styling bugs nonexistent.

Following our performance focus for this release, we have also changed how Web Messenger is loaded into a website: now it’s asynchronous. This will significantly improve your website load time when including Smooch, and lead to an overall snappier experience.


The new SDKs include a few API changes mainly around the way you initialize them. To upgrade to the latest version follow our instructions for each of the SDKs: Web Messenger 4.0, Android SDK 5.0 and iOS SDK 6.0.

If you're just starting out, the Smooch dashboard will point you to use the latest versions.

What’s next

This new SDK release sets us the trajectory for future enhancements. You can look forward to us constantly improving and making our SDKs more powerful. We are already working on adding more rich capabilities to make it easy for you to deliver whole new types of messaging experiences.
