Compare push notification services (SNS, Notification Hubs, FCM, OCI Notifications).
Output will appear here...A comparison of push, SMS, and email notification services across AWS (SNS/Pinpoint), Azure (Notification Hubs/Communication Services), GCP (Firebase Cloud Messaging), and OCI (Notifications/Email Delivery), and native SMS support is the clearest capability gap: AWS SNS/Pinpoint and Azure Communication Services both offer native SMS sending, while GCP's FCM has no native SMS marketing capability at all (only Firebase Auth phone verification, a narrower use case), and OCI Notifications has no native SMS either, relying on webhook integrations to third parties like Slack or PagerDuty instead.
No, FCM's phone-related capability is limited to Firebase Auth phone number verification (for login flows), not a general SMS sending/marketing capability. For SMS campaigns on a GCP-centric stack, you'd need a third-party SMS provider (Twilio, etc.) integrated separately, GCP doesn't offer a native equivalent to AWS Pinpoint SMS or Azure Communication Services SMS.
For push notification delivery specifically, yes, there's no per-message charge as of the current comparison snapshot, which is a genuine differentiator versus AWS SNS's per-million pricing. That said, associated Firebase services you might use alongside FCM (Analytics, Remote Config for targeting) have their own usage considerations, so 'free push' doesn't mean the entire surrounding notification workflow is free.
Not natively, OCI Notifications has no built-in templating and is fundamentally topic-based routing to fixed endpoint types (email, HTTPS webhook, PagerDuty, Slack, Functions, Streaming), not a marketing-campaign-oriented service like Pinpoint. A templated multi-channel campaign on OCI would need custom implementation via Functions, it's not a configuration gap, it's a missing product category.
The comparison table is a static, hand-maintained dataset of feature rows grouped by category (overview, channels, routing, targeting, pricing) with free-text search across all fields; it's a reference snapshot, not a live specs feed, verify current channel support and pricing directly with the provider before a notification platform selection.
Don't assume GCP or OCI have an SMS-sending equivalent to AWS/Azure just because they're full-featured cloud platforms, this is a genuine product gap on both, requiring a third-party integration if SMS is a requirement.
FCM's free push pricing makes it attractive purely on push-notification cost, but evaluate the full notification workflow (segmentation, analytics, templating) it lacks compared to Pinpoint before assuming FCM alone replaces a marketing-notification platform.
OCI's webhook-based fan-out (Slack, PagerDuty, email) is well suited to operational/infrastructure alerting but is a poor fit for customer-facing marketing notifications, match the OCI Notifications use case to ops alerting, not customer engagement campaigns.
