Advanced In-App Messaging SDK

Deliver perfectly timed, highly contextual in-app messages without slowing down your application. Trigger rich UI overlays instantly from the Edge with zero client-side bloat.

Zero-Latency Triggers via Edge-Native Architecture

When a user performs a critical action inside your application, delaying their reward or notification by even a second can ruin the experience. Legacy systems rely on sluggish, centralized servers to evaluate user behavior before triggering an overlay. VipulPush utilizes an edge-native architecture for our advanced in-app messaging SDK. Behavioral triggers and logic are evaluated directly at the edge node closest to the user. This guarantees that your contextual messages, onboarding modals, and promotional overlays appear instantly with absolute zero latency.

A True Zero-Bloat SDK for Maximum Performance

Integrating a third-party messaging SDK often means sacrificing your app's performance. Traditional tools bundle massive JavaScript payloads or heavy native libraries that severely damage load times and drain battery life. We built our advanced in-app messaging SDK with a relentless focus on zero bloat. The integration is incredibly lightweight, loading asynchronously and executing outside of the critical rendering path. Your application maintains its blazing-fast speed and flawless Core Web Vitals while still delivering rich, interactive messaging experiences.

Unlimited Impressions with Flat-Rate Pricing

In-app messaging should be about maximizing engagement, not worrying about your monthly bill. Unfortunately, the standard industry model penalizes growth by charging you per impression or per active user. VipulPush disrupts this with transparent, flat-rate pricing. Because our edge infrastructure is highly optimized, we pass the compute savings directly to you. Whether your advanced in-app messaging SDK serves a thousand impressions or a hundred million during a viral spike, your costs remain completely flat and predictable.
