Custom domains
made easy.

AppMasker simplifies white-labeling, custom branding, and custom domains for your web app.

White-labeling your SaaS is complex and expensive...

Here's just a few things you'll have to cover during your months-long refactor.

Domain / DNS

Configure another web-server to accept new domains and manage TLS certificates.

UI Refactoring

Your UI needs to swap layouts, images, text, and other dynamic values for every client based off the hostname.

API Context

API endpoints need to handle CORS securely. Cookie management can be a mess because of this.

Deployment and Automation

Minimizing manual onboarding effort is very complex for white-labeled / self-hosted apps.

...but it's SO worth it

The payoff for white-labeling your SaaS is substantial!

More Money

White-label deals command a higher price tag from enterprise customers. Collect a cut of future resales made by MSP clients and SaaS resellers.

Less Support

Resellers of your app handle support for their customers, which means less work for you.

Free Marketing

White-label resellers will market to their customers while you reap the benefits.

AppMasker simplifies white-labeling and custom domains so you can make more $$

BYOD: Bring Your Own Domain

AppMasker enables your customers to use a subdomain or their root domain on your app (often called vanity domains).

Subdomains made easy

Just want to offer subdomain accounts? AppMasker makes client subdomains a breeze.

Root Domains for full white-labeling

White-label your app with your client's own domain. Ideal for SaaS resellers, Managed Service Providers, and enterprise users.

White-label your entire app,
or just some of it.

AppMasker allows for any level of per-domain customization that you desire.

Images and Files

Use the same url path for the same type of image or file for all clients. Upload your files to AppMasker or have us redirect to their hosted url.
