Push notification software sends messages directly to users’ devices and browsers — app push, web push and increasingly cross-channel (email, SMS, in-app) — to re-engage users, recover carts, announce updates and drive return visits. The category spans easy all-around tools with generous free tiers, enterprise customer-engagement platforms that orchestrate push alongside other channels, mobile-first enterprise specialists, web-push-focused e-commerce tools, and free developer messaging layers. The right choice depends on whether you need simple push, full cross-channel orchestration, web or mobile focus, and your scale.
This guide compares five of the most widely used push notification platforms in 2026 across pricing, ideal use case and standout strengths, each linking directly to the provider so you can get started.

How to choose the right push notification software
Match the platform to your channels, focus and scale. Most teams wanting an easy, capable, affordable push tool — covering mobile and web push with a genuinely generous free tier — are best served by OneSignal, the popular all-around choice. Larger companies wanting to orchestrate push as one channel within sophisticated cross-channel campaigns (push, email, SMS, in-app) get the most from Braze, a leading customer-engagement platform. Mobile-first enterprises with demanding app messaging needs are well served by Airship, a long-established mobile engagement specialist. E-commerce and content sites focused specifically on web push to recover carts and drive return visits get strong value from PushEngage. And developers wanting a free, reliable base layer to build push into their own app should use Firebase Cloud Messaging (FCM), Google’s free messaging infrastructure. Two essentials: decide whether you need simple push or full cross-channel orchestration, since that separates the affordable tools from the enterprise platforms; and respect opt-ins and frequency, because push is intrusive and aggressive notifications drive users to disable them entirely — losing the channel.
Frequently Asked Questions
What is push notification software?
Push notification software sends messages directly to users’ devices and browsers — app push, web push and increasingly cross-channel (email, SMS, in-app) — to re-engage users, recover carts, announce updates and drive return visits. It ranges from easy tools with free tiers to enterprise engagement platforms, web-push specialists and free developer messaging layers.
What is the best push notification software in 2026?
It depends on your needs. OneSignal is the popular all-around choice with a strong free tier, Braze is best for enterprise cross-channel engagement, Airship is best for mobile-first enterprises, PushEngage is best for web push and e-commerce, and Firebase Cloud Messaging is best for developers wanting a free base layer.
What’s the difference between web push and app push?
App push goes to a mobile app on a user’s phone (requiring your app to be installed), while web push goes to a browser (desktop or mobile) after a user opts in on your website — no app needed. Web push is great for e-commerce and content sites to drive return visits; app push is for engaging mobile app users. Some tools do both; others specialize.
Is push notification software free?
Some options are genuinely free or have generous free tiers — OneSignal offers a strong free tier, and Firebase Cloud Messaging is free infrastructure for developers. Paid plans (and enterprise platforms like Braze and Airship) scale by subscribers, messages or features. For many small and mid-size teams, OneSignal’s free tier is enough to start, upgrading only as volume or channel needs grow.
How often should I send push notifications?
Sparingly — push is intrusive by nature, and users who feel spammed will disable notifications entirely, permanently costing you the channel. Send fewer, genuinely valuable, well-timed notifications (order updates, relevant offers, meaningful alerts) rather than frequent broadcasts. Respecting opt-ins and frequency keeps users subscribed and engaged, whereas over-messaging quickly burns out one of your most direct channels.
