What Is Google AI Studio Custom URL? A Complete Guide to Publishing Web Apps with *.ai.studio Subdomains

One of the biggest headaches when building AI apps isn't writing prompts—it's figuring out how to quickly share your finished prototype with clients, managers, or the broader community. In the past, you had to set up your own server, handle DNS resolution, and sometimes pay for a domain just to let someone access your app.

Google AI Studio's new Custom URL feature removes all of that friction. Once you've built your application in the built-in Build Mode, you can assign a memorable custom URL at publish time—no extra steps required.

Think of it as issuing your AI creation a personalized passport on the spot—no paperwork, no waiting. The whole world can visit your AI webpage in seconds.

The One-Line Summary

Google AI Studio's Custom URL feature lets developers publishing full-stack web apps in Build Mode assign a custom *.ai.studio subdomain directly—eliminating complex DNS setup and cloud hosting costs.

What Problem Does It Solve?

Before Custom URLs arrived, developers faced a string of friction points when sharing AI projects:

  • Complicated deployment: Even after writing the code, you still had to upload it to Vercel or Google Cloud Run and manually configure API keys and environment variables.
  • Hard-to-remember URLs: Auto-generated random URLs like app-12345-abc.run.app are long, forgettable, and unsuitable for presentations or portfolios.
  • High DNS configuration barrier: Using a branded custom domain requires owning one and configuring DNS records (CNAME, A records)—a steep climb for anyone without a web engineering background.
  • Hosting costs: Paying for hosting just to demo a Hackathon project or a proof-of-concept can feel like overkill.

Google AI Studio's Custom URL handles all of these steps within a single platform.

Core Features

1. Built into Build Mode — One-Click Publishing

Once you've designed a full-stack application in Google AI Studio's Build Mode, just click the Publish button in the upper right corner. A publish settings panel will appear, and you'll see the Custom URL input field right there.

2. Freely Assign Your Own *.ai.studio Subdomain

Type in the name you want—as long as it isn't already taken, the system reserves it for you immediately. For example, my-creative-bot.ai.studio. Your demo URL becomes polished and brand-ready.

3. Easy Domain Transfer and Management

If you want to reassign a Custom URL to a new application, simply unpublish or delete the original app. Once the URL is released, it can be immediately assigned to a new project.

How Does a Custom URL Compare to Traditional Deployment?

The table below summarizes the differences between Google AI Studio Custom URL and other common publishing methods:

Feature AI Studio Custom URL Traditional Cloud Run External Platform (e.g., Vercel)
URL format *.ai.studio (customizable) *.run.app (random) *.vercel.app or custom domain
DNS setup None required None / manual for custom domain Manual for custom domain
Code export Not needed — one-click publish Deploy via Git or CLI Export to GitHub, then connect
Best for Quick prototypes, hackathons, PoCs Production, high-load enterprise apps Frontend frameworks, branded domains

What Non-Engineers Need to Know

For product managers, marketers, and AI creators, this feature means the barrier to productizing AI has never been lower.

You no longer need to ask an engineer to spin up a server or configure a domain. Once you've tuned your prompt and designed your interface in AI Studio, you can publish it yourself and share a professional-looking URL with partners. This dramatically cuts communication overhead and speeds up product concept validation.

Who Is It For?

  • AI creators and individual developers: Quickly build a personal portfolio or AI tool demo.
  • Hackathon teams: Ship a working, shareable web app with a great URL for judges—fast.
  • Product managers and business development: Present custom AI solutions with a branded, polished demo URL.

Who Might Not Need It?

  • Enterprises requiring a fully independent domain: Scenarios like ai.yourcompany.com still require exporting the code and deploying to Google Cloud Run or Vercel.
  • Systems with strict security and compliance requirements: Custom firewalls, IP restrictions, or complex database connections still call for a traditional backend deployment.

How to Get Started

  1. Sign in to Google AI Studio.
  2. Go to Build Mode and design your application.
  3. Once everything is working, click Publish in the upper right corner.
  4. In the settings panel, enter your desired subdomain in the Custom URL field (e.g., my-app).
  5. Confirm, and within seconds your app will be live at https://my-app.ai.studio.

[!IMPORTANT] Custom subdomains must comply with Google's Terms of Service. URLs associated with fraud, phishing, or other policy violations may be revoked or disabled at any time.

Our Take

Google AI Studio's Custom URL feature is another clear signal that Google is positioning AI Studio as an AI application incubator, not just an API playground.

It's evolving into a seamless develop-and-publish platform. By lowering the barrier on the "last mile" of sharing and deployment, Google attracts more lightweight developers and non-traditional technical users into its ecosystem. This kind of low-code / no-code publishing experience is shaping up to be a key battleground among major AI platforms going forward.
