Show HN: StemJSON – a language for LLMs to extend native mobile apps on the fly
StemJSON is a new declarative language designed to allow LLMs to generate and update native mobile app UI and logic on the fly. It aims to enable server-driven UI and AI-generated features without requiring full app binary updates.
Why it matters
It provides a framework for more dynamic, AI-driven mobile application development, potentially reducing the need for traditional app store update cycles.
StemJSON is a new declarative language that turns descriptions into native apps - written by AI, pushed by your backend, or shaped by your users.
What it is The language AI uses to build native apps StemJSON is a declarative language based on JSON, well-suited for AI to generate comprehensive, performant native app UI and logic - whether building new apps or extending existing ones.
The format is open. Drop it into AI tools, prototyping environments, IDE extensions, or alongside hand-written code to simplify and accelerate native app design, development, and delivery.
