How do I publish my app to my own custom domain?
Go to Domains tab, click Add a custom domain, then enter your domain name.
What are DNS records? Where/How do I add them?
You purchase your domain at a Domain registrar (like GoDaddy, or Name.com). You build and host your app with Hercules. You use DNS records to connect your domain to Hercules so the internet knows where to find your website. You must set up your DNS records following the instructions we give you:| Type | Name | Value |
|---|---|---|
| A | @ | 104.18.220.38 |
| CNAME | www | cname.onhercules.app |
| CNAME | _acme-challenge | <your-unique-acme-challenge-value> |
| TXT | _cf-custom-hostname | <your-unique-custom-hostname-value> |
Will this work for www too?
Yes. When setting up your custom domain, you can choose to have all subdomains redirect to your root domain (e.g. www.myapp.com would redirect to myapp.com).
My domain isn’t working, what do I do?
Click Having trouble connecting a domain? to open the diagnostics tool. This will check your DNS configuration and show you exactly what’s wrong. The diagnostics will identify common issues like incorrect DNS record types, missing DNS records, or DNS propagation delays.
Can I connect multiple domains to the same app?
Yes. You can connect as many custom domains as you’d like to a single app. All domains will show the same content.Additional FAQ

My domain doesn't work on my device but works on someone else's?
This is usually a DNS caching issue. Try clearing your browser cache, flushing your DNS cache,
or waiting a few hours. Different ISPs and devices cache DNS records for different amounts of
time.
