About

BDUI Go

Read full description

BDUI Go is a runner for server-driven UI: it opens apps described by JSON schemas and renders them natively β€” the way a browser opens websites, only for mobile screens. A schema is data, not code: it declares which components to show and which HTTP requests to make. BDUI Go renders that data with native Compose Multiplatform components β€” no webview, no downloaded executables. Scan a QR code or open a link, and the app it points to loads instantly. When its author publishes an update, you see the new screens in seconds β€” no reinstall, no waiting for a new version. TRY IT RIGHT AWAY β€” NO ACCOUNT NEEDED β€’ Component showcase: every BDUI building block, rendered live from JSON β€’ Currency exchange demo: live rates from the Frankfurter API with pull-to-refresh β€’ Weather demo: city search and forecasts via the Open-Meteo API β€’ Auth demo: automatic token injection with transparent refresh and retry HOW IT WORKS 1. An author describes an app in a JSON schema and publishes it 2. They share a link or a QR code 3. You open it in BDUI Go β€” the screens render natively on your iPhone Every publish reaches users in seconds. Authors can switch between dev, staging and production channels and roll back to any version in one click. FEATURES β€’ Native rendering (Compose Multiplatform) β€” no webview β€’ Offline cache: previously opened apps launch even without a network β€’ Recents list, with any app pinned as the default one that opens on start β€’ Host allow-list: a schema declares the hosts it may call, and requests to anything else are blocked β€’ Declarative token auth for API-backed apps β€’ Universal Links: https://bdui.io/a/… opens directly in BDUI Go PRIVATE BY DESIGN No accounts, no ads, no analytics, no tracking. The camera is used only to scan QR codes, entirely on your device.
