StemJSON

StemJSON lets a published mobile app grow new native features from plain words, so users get functions the app never planned for and developers can serve individual needs without building each one or shipping a release. Key capabilities: • Describe a new feature in plain language inside the app • Generate declarative StemJSON modules from those descriptions • Validate every module at runtime before it runs • Build features from real iOS and Android native components • Enforce limits the app developer sets in advance • Customize layouts, logic, and data per user without new releases The closing step checks each generated module and assembles it from genuine native parts, so results look and perform like hand-built screens. Developers stay in control through predefined boundaries that define what users can request and what the runtime is allowed to build. Because the format is a open JSON specification, the same modules can be pushed from a backend, written in tools like StemStudio, or shaped directly by end users. Built for mobile developers, product teams, and app publishers who want personalized features and faster iteration without the overhead of a full release cycle. Typical use cases include custom dashboards, user-defined workflows, server-driven interface updates, and tailored tools for niche customer segments. Teams can extend a shipped app as needs emerge, keeping the experience native while responding to real user requests.
