Custom Domains

Connect your own domains as custom domains to your applications.

By default every application is assigned a subdomain. We generate a unique slug from the name which serves as the default subdomain. For example if your application is called My Test Application the generated subdomain would be: If the slug is already taken, our system adds a number at the end to make it unique, for example

Custom Domains

Subdomains are a great way to get started quickly or try out how applications work, but for real usage it's recommended to add a custom domain. Every application supports up to 10 custom domains. You can simply point your domains with an ANAME/ALIAS record to our load balancer. ANAME records allow us to be flexible how we assign IP addresses internally, the downside is that some DNS providers still do not support it. Since we completely own our IP space, we also allow an A record to be added instead as a fallback option.

TLS Certificates

For every custom domain we will automatically add a free TLS certificate. Issuing and renews are automated by our platform. We currently issue ACME certificates powered by Google, Let's Encrypt and ZeroSSL.

Custom Certificates

Custom TLS certificates are currently not supported.

Default Domain

If you have added multiple domains to your application, but one domain should be the main domain name all others redirect to, we offer the option to set it as default domain. Setting a default domain will result in all other domains (including the subdomain) to redirect via 301 status code to your default domain.
