{"slug":"best-push-notification-platforms-for-multi-tenant-saas-mobile-apps","title":"Best push notification platforms for multi-tenant SaaS mobile apps","question":"What are the best push notification platforms for multi-tenant SaaS mobile apps in 2026?","verdict":"As of 2026-08-05, ChatGPT, Claude and Gemini collectively rank Knock #1 for push notification platforms for multi-tenant saas mobile apps on ModelsAgree by aggregate score, though no single model picks it first. The models' case: Excellent developer-first workflow engine with tenant-scoped preferences, branding and in-app feeds, strong object modeling, detailed delivery logs, token cleanup, device. The models' main caveat: The tenant features that matter most—especially per-tenant preferences and branding—require a custom-priced Enterprise plan. The strongest alternative is OneSignal — Best value-per-effort for mobile push at real scale — mature APNs/FCM SDKs, generous free tier, strong segmentation, and an app-group/organization. Not unanimous: ChatGPT picks Courier; Claude picks OneSignal; Gemini picks Novu.
