OTT App Builder
Design and customize your branded OTT app from one admin panel. Set branding, colors, borders, profile icons and menus for TV, desktop, mobile and tablet - and preview every change live before you publish.



Build and Customize Your Custom OTT Platform for TV, Desktop, Mobile & Tablet
inoRain's App Builder puts your whole streaming UI in one admin panel and lets you create your own OTT platform without writing a single line of code. It is the visual layer of inoRain's OTT middleware - set your branding, colors, borders, profile icons and menus, then tailor the layout for TV, desktop, mobile and tablet, and watch every change render live before you publish.
The result is a fully custom OTT platform that looks unmistakably yours on every screen your viewers use.

Everything You Can Customize
One panel, total control. The App Builder mirrors the five control groups in your admin panel. Change a setting, see it instantly in the live preview, then save when it's right.
Branding
Upload your logo, splash artwork and brand assets so your custom OTT platform feels unmistakably yours from the very first screen.
Color settings
Define primary, secondary and background colors plus button styles to match your palette and keep contrast crisp on every screen.
Border settings
Dial in corner radius and border treatments for cards, posters and buttons - from sharp and modern to soft and rounded.
