InAppStory features and specs

  • In-App Stories
    Native, Instagram-style Stories that surface product updates, offers, and tutorials at the right moment inside the app. Interactive widgets, triggers, targeting, and analytics turn passive taps into feature adoption, zero-party data, and shoppable journeys.
  • Gamification
    A Game Center with 12+ ready-to-use game mechanics (Wheel of Fortune, Mystery Boxes, Advent Calendar, Puzzle, Match 3, Memories, and more) shaped by 1,000+ real campaigns. Pick a game, customize design and rules with no code, and launch across web and mobile to drive engagement, retention, and promo-code distribution โ€” with custom games available on request.
  • In-App Messages
    Personalized, event-triggered messages delivered as full-screen banners, modals, bottom sheets, and pop-ups at natural touchpoints in the user journey. Advanced targeting on segments, behavior, and CDP data, dynamic placeholders for personalization, and real-time analytics make them far more effective than push for actions that need immediate context.
  • SMART Banners
    Targeted in-app banners that keep offers, loyalty rewards, countdowns, and partner placements visible exactly where users make decisions โ€” without interrupting the flow. They reinforce stories, in-app messages, and mini-games, and support upsells and monetization by turning existing intent into action.

Nullstack features and specs

  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing InAppStory and Nullstack.

Why should a person choose your product over its competitors?

InAppStory's answer

Most competitors do Stories and stop there; InAppStory lets you consolidate Stories, mini-games, in-app messages, and zero-party data collection into one SDK and dashboard, replacing several point tools. It's built for measurable outcomes and backed by an in-house Creative Studio, a 30-day free trial, and proven scale of 25M daily viewers and 30,000+ stories created.

What's the story behind your product?

InAppStory's answer

Founded by CEO Vlad Lastovsky, InAppStory started from a simple insight: apps struggled to hold attention against social media's video and Stories formats, so he built a native way to bring that format inside apps. It has since grown from a single Stories tool into a full engagement platform (Stories + games + messaging + banners), now an international company.

What makes your product unique?

InAppStory's answer

InAppStory is an all-in-one in-app engagement platform, not just a Stories tool โ€” it combines native Stories, fully playable in-Stories mini-games, in-app messaging, banners, and interactive widgets in one no-code console. It runs through a single SDK for iOS, Android, Flutter, React Native, and web, so teams update everything in real time without developers.

How would you describe the primary audience of your product?

InAppStory's answer

Product, marketing, and growth teams at mid-market and enterprise companies with an existing mobile app who want better engagement, onboarding, and retention without heavy engineering. It's strongest in e-commerce and retail, finance, telecom, and travel, with global adoption across EMEA, the Middle East, and CIS.

Which are the primary technologies used for building your product?

InAppStory's answer

InAppStory ships as native and cross-platform SDKs โ€” Swift (iOS), Kotlin/Java (Android), Flutter, React Native, and web โ€” with story content rendered via a WebView layer for rich HTML/CSS/JS interactivity, so new formats deploy without app updates. Content, targeting, and analytics run from a cloud-based no-code console that integrates with tools like Google Analytics, Amplitude, and CDPs.
