Nudj’s white-label surface is pragmatic: a custom domain for your user-facing URLs and a theme system that matches the look of the embedded experience to your brand.
There is no Nudj-supplied native mobile app published under a customer’s developer account. If a conversation with your account manager suggests otherwise, raise it — the platform does not currently ship that product.

​
Custom domains

​
Setting one up

A subdomain such as engagement.yourcompany.com points at Nudj with a CNAME record to cname.vercel-dns.com; a whole domain uses an A record to 76.76.21.21. Nudj adds the domain first and sends you the exact records, and the certificate is issued automatically once they resolve. Step-by-step guide: Custom domains. API reference: Custom Domains. Each domain in the admin panel’s Domains tab has an open button, so teams can check the branded address before announcing a launch.

​
Multiple domains per organisation

An organisation can have multiple verified domains, used for regional sites, white-labelled partners, or staging. The Shopify widget preview prefers a custom domain over the default Nudj address, so in-merchant admin previews render against the branded URL.

​
Theming

​
Source of truth

Theme variables live on the community.theme object. The admin panel’s Branding & Theming section is the canonical editor. Theme values cascade from the organisation’s default community down to child communities; child communities can override individual variables. Reference: Widget Theming System in the engineering repo has the full variable list, data flow, and CSS variable mapping.

​
Theme presets

PR #1886 added theme presets — pre-built configurations that ship values for colours, typography, spacing, and component shape. Admins can pick a preset in the Shopify embedded admin and tune individual variables without starting from scratch.
