pageflare vs
OneSignal.
OneSignal is a great push notification service — but push is one piece of a PWA. pageflare manages your entire progressive web app: install prompts, offline support, manifest, analytics, and push notifications — with site performance optimization baked in. One platform instead of two.

Push is one feature.
PWA is a platform.
Install is the foundation
Push notifications only reach users who've opted in. Getting users to install your PWA — or even visit repeatedly — requires managing install prompts, guided flows, and engagement hooks. pageflare handles all of it.
Offline builds trust
An app that works without connectivity feels native. A branded offline page with cached content keeps users engaged even when their connection drops. OneSignal has no answer for this.
Speed drives opt-in
Users are far more likely to install and opt into notifications from a fast-loading site. pageflare's built-in optimization means your PWA loads fast before any install or push prompt appears.
One SDK, not two
Adding OneSignal to an existing site means another SDK, another service worker conflict to debug, another vendor to trust with user data. pageflare consolidates everything into one script.
Manifest matters
A correct, complete web app manifest determines whether your PWA looks right when installed — the right icon, splash screen, and display mode. pageflare manages and validates it automatically.
Analytics in context
Knowing your push click rate means nothing without knowing your install rate. pageflare tracks the full funnel from first visit to install to push opt-in — so you optimize the right step.
The complete PWA platform. Not just push.
