Nimbus SDK 3.0 is available today for iOS, Android and Unity. It is our lightest, fastest, most dependable SDK yet: a smaller footprint in your app, ads that start sooner, and an integration that takes less of your engineering team’s time.
Smaller framework
↓-25%
Faster mapping at app launch
↑+83%
Fewer allocations per request
↓-19%
Less code to integrate
↓-50%
Measured on iOS 3.0 against 2.x; the integration figure is an average.
What makes 3.0 great
01
Nimbus is stable even when your app is busy
3.0 is built for apps that do many things at once
Ad loading and rendering run alongside your app’s own work without getting in its way, so ads behave the same way in every user session
02
You get a lighter, faster-launching app
Our SDK is 25% smaller than before and maps into your app faster at launch
Your app is smaller, and starts up faster for your users
03
Video ads start sooner
On iOS, our Quickplay renderer loads video creatives faster, so users see the ad right away
More of the impressions you win become revenue you capture
04
An improved rewarded experience
Rewarded ads show a visible countdown so users know when they can close the ad
The SDK fires one clear reward-earned event when the reward is due, so your reward logic has one signal to listen for
05
Plug-and-play SDK demand
Add a new SDK demand partner with a single line of code
Our 3.0 SDK absorbs demand partner updates automatically, so fixes and features reach you without waiting on a Nimbus release
06
Same code on every platform
Our SDK works the same way on iOS, Android and Unity
Your team can nearly copy integration code from one platform to the next
“We were publishers before we were an ad platform, so we know what an SDK costs an app in size, user experience and engineering hours. 3.0 is the SDK we always wanted to ship, and we’re proud to put it in publishers’ hands.”
An updated engineering spec
One framework. 3.0 ships as a single code-signed NimbusKit framework with everything needed to run ads.
Adapters as packages. Each SDK demand partner adapter is a separate package you can upgrade or pin independently.
Swift 6 native. The public API is fully thread-safe, with Swift 5 compatibility for teams that aren’t there yet.
An API that reads top to bottom. Async and fluent; a typical iOS integration takes about half the code it did before.
Measured on iOS. The framework maps into the app 83% faster at launch, uses about 10% less heap memory and makes 19% fewer allocations per request.
Android. Static render rates are substantially improved.
Moving to 3.0
3.0 supports iOS 15 and up through Swift Package Manager or CocoaPods, Android through Gradle, and Unity through the Unity package. Upgrade guides and the full API reference are in the Nimbus docs.
