# OneSignal alternatives for subscription apps

The main OneSignal alternatives for a subscription app are Whisperr, Customer.io, CleverTap, Airship and Braze. If you mostly need retention, Whisperr decides who gets a message and writes it, and can still send push through your OneSignal account. If you need a bigger campaign platform, Customer.io and CleverTap have published prices, and Braze sells by quote while Airship publishes no prices (a quoted platform plus a self-service tier).

## Whisperr

Whisperr adds the part OneSignal leaves to you: deciding which users need a retention message, writing it for each of them, and measuring it against a 10% holdout. It reads product events and subscription events from RevenueCat, Superwall or Adapty, and sends through your own providers, including OneSignal.

## FAQ

### Do I have to leave OneSignal to use Whisperr?

No. Whisperr can use your OneSignal account as its push provider. OneSignal keeps delivering notifications while Whisperr decides which users get a retention message and writes it.

### Why look for a OneSignal alternative?

Usually because sending isn't the hard part. Deciding who should get a message, what it should say, and whether it kept anyone takes work that OneSignal leaves to you. Teams then want either more campaign tooling or retention that runs on its own.

### Which alternative is closest to OneSignal in price?

Whisperr has a free plan up to 1,000 users and paid plans from $49 a month. CleverTap Core is listed at $85 a month and Customer.io Essentials starts at $100 a month. Airship and Braze don't publish prices.

### Which alternative measures lift against a control group?

Whisperr holds back 10% of users by default and shows retention and revenue kept with a confidence interval once each group has 200 users. Braze has a Global Control Group with an uplift report, CleverTap has an account-wide System Control Group, Airship has holdout experiments, and Customer.io runs holdout tests per email message.
