BDUI Go vs Vays

BDUI Go opens mobile apps that are described in JSON: their screens, navigation and API requests. Authors create these apps in the BDUI web dashboard and share a link or a QR code. You open it in BDUI Go, and the screens render natively on your iPhone. Each app opens inside BDUI Go, so there is nothing extra to install. When the author publishes an update, you get the new version without reinstalling anything or waiting for an App Store update. A JSON description is data, not code: it lists which components to show and which requests to make. BDUI Go renders it with native Compose Multiplatform components — no webview, no downloaded executables. TRY IT RIGHT AWAY — NO ACCOUNT NEEDED • Component showcase: every building block, rendered live from JSON • Currency rates: live exchange rates from the Frankfurter API, pull down to refresh • Weather: city search and forecasts from the Open-Meteo API • Sign-in demo: an app that signs in to an API and keeps the session fresh automatically More demos with QR codes — a tea shop, a live earthquake feed, a cafe menu — at https://bdui.io HOW IT WORKS 1. An author describes an app in JSON in the BDUI web dashboard and publishes it 2. They share a link or a QR code 3. You open it in BDUI Go — the screens render natively on your iPhone Authors can try changes on a separate test channel before publishing them, and roll back to any earlier version in one click.
