Chumbaq or OneSignal? An honest answer.
The best-known push tool, now with a smaller free plan. Here's where each one wins, including the rows where we lose.
Choose OneSignal if
- You send at very large scale and want a vendor with years of track record
- You need a SOC 2 report today
- You're happy with push and in-app and don't need WhatsApp
Choose Chumbaq if
- You've outgrown 1,000 MAU and want a free plan that covers a real app
- You want WhatsApp in the same journeys as push and email
- You want campaigns scored on purchases against a control group
- You want the option to run it on your own servers

What changes when you switch
The free plan got smaller
OneSignal's free plan now stops at 1,000 MAU for mobile push and in-app. Chumbaq's covers 2,500.
Keep your FCM and APNs setup
Chumbaq sends through the same credentials, so you don't touch your push certificates.
Prove the push paid off
A control group shows what each campaign actually added in sales.
Chumbaq and OneSignal
Can I run Chumbaq next to OneSignal while I switch?
Yes. Both read the same FCM and APNs tokens. Run them side by side for a release or two, then turn OneSignal off.
Will my users need to re-subscribe?
No. Notification permission belongs to your app, not to OneSignal. Chumbaq picks up each device's token when the new app version opens.
Bring your users back
Free up to 2,500 monthly active users. No card, no sales call.
