Customization overview

Everything Atlas shows a user — the sign-in page, the account portal, the emails and text messages it sends — can be made to look and sound like your product, not Atlas. Customization is per-instance, so your Development and Production instances can differ while you get it right.

Make Atlas look like your product

What you can customize

Localization

Where to configure it

Open the dashboard, select the instance you're editing, and use the Customization section. Changes apply to the hosted pages, the embed widget and the SDK components together — you style once and it lands everywhere Atlas renders UI.

Customization is per-instance and does not copy from Development to Production. When you go live, reproduce your branding, templates, custom domain and localizations on the Production instance deliberately.
