Reliable at scale

Custom Domains Built for Scale

Manage hundreds or thousands of domains for your SaaS app with automatic SSL, DNS verification, and secure activation.

Works With Your SaaS App

Connect custom domains for your users’ instances directly to your SaaS platform — no extra configuration required.

Automatic SSL & DNS Verification

SSL certificates and DNS ownership verification are fully automated — domains activate only after verification.

Programmatic Domain Management

Add, verify, and manage your users’ domains programmatically through API — no UI required.

Uptime & Reliability

Designed for SaaS at scale with robust infrastructure — fair-use bandwidth ensures your app stays live reliably.

Built-In Security

Automatic SSL, Web Application Firewall (WAF), and DDoS protection keep all custom domains secure by default.

Scales With Your Users

Whether you have 100 or 10,000 users, the platform handles domain provisioning, verification, and SSL automatically — no manual intervention required.

Scale with confidence

How SaaS Domain Management Works

Integrate custom domains for your users in four simple steps — secure, automated, and scalable.

  • Step 1: Add your upstream

    Enter the URL where your app or platform is hosted.
    Example: customer1.saas.com

  • Step 2: Connect user domains

    Add the domains your users own or will point to your platform.
    Example: app.customer1.com

  • Step 3: Verify DNS

    Automatically verify ownership via DNS. Instructions can be sent to your users or handled programmatically through the API.

  • Step 4: Activate with SSL

    Once verified, the domain goes live with a fully provisioned SSL certificate — secure and ready for your users.

Frequently Asked Questions

Answers to common questions about offering custom domains for your users.

Can I manage domains for hundreds of users?

Yes. Our system is designed for multi-tenant apps and can handle hundreds or thousands of user domains at scale, with automated SSL and verification.

Is there an API for programmatic domain management?

Yes, API access is available via our early-access program. It allows you to add, verify, and manage domains for your users without a UI.

How secure is the domain connection for my users?

All domains use automatic SSL, DNS verification, and optional WAF/DDoS protection to ensure secure connections for every user.

Can I integrate this with internal tools or dashboards?

Absolutely. You can assign custom domains to internal tools or dashboards, giving teams secure and easy access while maintaining central control.

What happens if a user misconfigures their DNS?

Domains only activate after successful DNS verification, so misconfigurations won’t go live. Our API and dashboard provide clear error messages for troubleshooting.

Do you support enterprise or self-hosted deployments?

Yes. For organizations that require complete control, TLS termination, and compliance, we offer a self-hosted enterprise option with dedicated support.
