Set Up a Custom Domain (Add-On)

Updated February 02, 2026 20:12

Overview

Note: Custom Domains is an add-on feature. Please reach out to your Customer Success Manager or our Support Team to learn more about availability and pricing.

The Walnut Custom Domains add-on lets you serve demos, playlists, and deal rooms from your own branded domain instead of app.teamwalnut.com.

This creates a seamless, immersive experience for prospects and customers while preserving all Walnut analytics, integrations, and security standards.

What's Included:

✅ Branded Domain Prefix:
Serve demos, playlists, and deal rooms under a branded domain (e.g., demos.yourcompany.com).
✅ Immersive, On-Brand Experience:
Removes the Walnut branding tab in embedded demos for a cleaner, on-brand viewer interface.
✅ Secure Hosting:
Includes automatic SSL provisioning and TLS 1.2 encryption.
✅ One Custom Domain per Instance:
Each Walnut account supports a single custom domain.

Example:
Default: https://app.teamwalnut.com/demo/?demoId=1234
Custom domain: https://demos.yourcompany.com/demo/?demoId=1234

Demo Experience: Without vs. With a Custom Domain

Feature	Without Custom Domain	With Custom Domain
Demo URL	app.teamwalnut.com	Your branded domain (e.g. demos.yourcompany.com)
Branding	Walnut-branded interface	Fully on-brand experience
Embedded Demo Experience	Walnut tab visible	Walnut tab removed automatically
Trust & Credibility	Third-party domain	First-party branded experience
Analytics & Integrations	Fully supported	Fully supported
Security	HTTPS + TLS 1.2	HTTPS + TLS 1.2 with custom SSL

Note: The Walnut tab is only visible when a demo is embedded on an external page. When a demo is opened directly in a browser tab using its share URL, the Walnut tab is not shown.

Embedded Demo Without a Custom Domain

👆The Walnut tab shown here appears by default in embedded demos. When the Custom Domains add-on is enabled, this tab is removed to create a more on-brand embedded experience.

Enable a Custom Domain

In this example, we’ll use:

Primary domain: awesome.com
Custom subdomain: demos.awesome.com

Create a CNAME record
Point demos.awesome.com to:
```
custom-domain.teamwalnut.com
```
⚠️ Make sure the destination is entered exactly as shown. Do not replace the words `custom-domain.`
Submit a support request
Use the Submit a request form. A Walnut Support Specialist will complete the setup and notify you when it’s live.
Copy your new link from the Walnut Library.
All new demo links will automatically use your branded domain.

Note: If you switch or update domains, please contact Walnut Support to refresh your custom domain configuration.

Changes to DNS Records

If your DNS records are changed or deleted, demos served from your custom domain may stop working.

If you plan to update your DNS settings, or if changes have already been made, please contact Walnut Support so we can review and update your custom domain configuration.

See a Broken Link?

This message may appear if your active CNAME record was changed, deleted, or no longer points to custom-domain.teamwalnut.com.

The good news is that your demos are still accessible. You can always open any demo using its default Walnut link (https://app.teamwalnut.com/demo/?demoId=1234), even if the custom domain is temporarily unavailable.

To fix a broken link:

Verify that your CNAME record points to custom-domain.teamwalnut.com
Contact Walnut Support to update your custom domain configuration

FAQs

Is a custom domain required?

No. Custom domains are optional, but recommended for customer-facing use cases.

Is this a paid feature?

Yes. Please contact your CSM for pricing and availability.

What happens if the DNS record changes?

If the CNAME record is removed or updated incorrectly, demos served from the custom domain will stop working. Default Walnut links will still function.
