When you deploy your project, CatDoes gives you a free URL like yourapp.catdoes.app. If you want to use your own domain instead (like www.yourcompany.com), you can set that up too.
Custom domains require a Starter plan or above.

​
How It Works

​
Step 1: Deploy Your Project

First, ask the AI agent to deploy your project. Just tell the agent something like “I want to deploy my project” and it will walk you through picking a URL and getting your app live at yourapp.catdoes.app. If you haven’t deployed yet, check out the Deployment page for more details.

​
Step 2: Ask for a Custom Domain

Once your project is deployed, tell the agent you want to use your own domain. For example, you can say “I want to use my custom domain” and the agent will guide you through the setup.

​
Step 3: Set Up Your Domain

You’ll need to go to wherever you manage your domain (like GoDaddy, Namecheap, Google Domains, Cloudflare, or any other provider) and point it to your CatDoes app. Here’s what to do:
  1. Log in to your domain provider.
  2. Find the DNS settings for your domain.
  3. Add a new CNAME record:
    • Name/Host: your domain or subdomain (for example www or app)
    • Value/Target: catdoes.app
  4. Save the changes.
DNS changes can take a few minutes to a few hours to take effect, depending on your domain provider.

​
Step 4: Come Back and Confirm

Once you’ve set up the DNS record, go back to CatDoes and let the agent know. The agent will verify the setup and get your custom domain connected. If the record isn’t showing up yet, the agent can check again in a few minutes. Your custom domain gets a secure https:// connection automatically.

​
How Many Domains You Can Add

Each project can have a set number of domains, depending on your plan. This includes your yourapp.catdoes.app URL. You can also add extra free *.catdoes.app URLs to the same project — no DNS setup needed. Just ask the agent. They count toward the same limit. To remove a domain, ask the agent.

​
Tips

Using a root domain like yourcompany.com (without www)? Many providers don’t allow a CNAME record there. Add an A record pointing to the IP address of catdoes.app instead — ask the agent if you need help.
If you’re not sure where your DNS settings are, search for “DNS settings” in your domain provider’s help pages — every provider has them, they’re just in different places.
You can always keep using your yourapp.catdoes.app URL even after setting up a custom domain. Both will work.
