Every product has a default *.sleekplan.app subdomain that you can use right away — for example, yourproduct.sleekplan.app. Sleekplan also uses this domain for links in customer notification emails. You can replace the default with any subdomain you own.

​
Use the default subdomain

Your default subdomain is assigned when you create a product and is visible in Settings → Widget. It is active immediately and Sleekplan uses it when sending customers email notifications that link to feedback posts or changelog items.

​
Connect a custom domain

1

Open domain settings

Go to Settings → Widget and click Change next to your current domain.
2

Enter your domain

Choose Custom domain and enter the full hostname you want to use.
Enter only the domain name — no scheme, no trailing slash. Sleekplan stores it as-is.
3

Add a CNAME record

In your DNS provider’s dashboard, add the following record. Replace feedback with the subdomain you entered in the previous step.DNS propagation may take minutes to 48 hours depending on TTL.
4

Wait for SSL to be provisioned

Sleekplan auto-issues a Let’s Encrypt certificate when a valid CNAME is detected. Provisioning takes 5–20 minutes; the domain returns an error during that window.
No manual certificate work is required; renewal is automatic.
