Firebase Cloud Messaging vs PushEngage

Firebase Cloud Messaging (FCM) delivers messages and notifications between servers and client devices over a reliable, battery-efficient connection. Senders can choose notification messages for display to users or data messages for an app to process. Messages can go to an individual device, groups of devices, or devices subscribed to topics; instant-messaging payloads can be up to 4096 bytes. Sending options include the Firebase Admin SDK, the FCM server protocol, and the Firebase console Notifications composer. Notification messages integrate with Google Analytics for engagement and conversion tracking, and A/B Testing with Remote Config supports testing notification variants. Setup guides cover Apple platforms, Android, web, Flutter, Unity, and C++. The JavaScript API works in browsers that support the Push API, including Chrome extensions using it. The web SDK requires HTTPS. FCM is free: its listed plan is free. Data in transit is protected with TLS, but FCM has no built-in end-to-end encryption; apps handling sensitive data must provide that protection themselves.

PushEngage is a messaging platform for websites and apps, with web push, app push, PWA push, desktop push, and in-app messaging. It also supports WhatsApp and chat widgets. Web push works with Chrome, Edge, Safari, and Firefox without an app install; native mobile push is available for iOS, Android, Flutter, and React Native. Audience segmentation, automation workflows, and API access are listed capabilities. Integrations include HubSpot, Shopify Plus, WooCommerce, WordPress, Magento, PrestaShop, Wix, and Zapier; the platform also provides a REST API and SDKs for web and mobile environments. The free plan supports one website or app, 200 subscribers, and 30 campaigns. Business costs $9 a month for up to 50,000 subscribers, Premium costs $15 a month for up to 100,000, and Growth costs $24 a month for up to 250,000. Paid plans bill by active subscribers, and unsubscribed users are removed automatically. Workflow counts and step limits vary by plan. PushEngage states that it is GDPR and CCPA compliant and offers a 14-day period to request a full refund if it is not a fit.
