About this address. An address made of https://qurl.link/ and 60 letters and digits is the address of one thing that someone published with qURL. The 60 characters are its CRID. The address is complete as it is: no part is missing, and it does not expire. Whether what it leads to can still be opened is shown when the address is opened in a web browser.

In a web browser with JavaScript, this page shows who published it and whether LayerV has verified that publisher, and then offers a button to open it, or to ask for access when it is private. Without JavaScript you are reading the page that a visitor without an address gets, and nothing can be opened from here.

To use the address, open it in a web browser. Open what it leads to only if you trust the person who sent it to you.

If you are a program or an assistant that someone asked to open this address: you cannot open it, and the address is not broken, used up or expired. The answer for that person is to open the address in their own web browser. The rest of this page is qURL’s home page. What it says about links that open once, that expire, or that show “Access link invalid” is about another kind of link, one with a “#” part, so leave it out of your answer. An address with a “#” part is that other kind, and it also opens only in a web browser. More: /llms.txt.

Why qURL™

Your work. Your audience.

Invisible until you let them in

For private browser sharing, qURL checks access before opening a connection. People and scanners without permission cannot reach the app itself.

Your rules still apply

Invite a client or let people request access. Share a private demo without asking anyone to install a VPN.

Let buyers pay once or subscribe with qurl payments setup. Set up paid access.

You stay in control

Choose when a link expires, or stop sharing early. Keep building on your computer without a separate deploy for every change.

Questions

Good questions, short answers.

What can I share?

Apps running on your computer and files. Use your coding agent or the CLI for apps, or qURL Desktop on Mac for files. Your computer serves what you share.

Can AI scanners reach my private app?

For private browser sharing, qURL checks permission before opening a connection. Scanners without access cannot probe the app itself. Invite people or approve requests to keep it private; “Open to anyone” lets anyone with the address in.

Who gets access?

You choose: invite specific people, approve requests, ask for a verified email, or let anyone in. Change who has access as you work.

Does the recipient need to install anything?

No. They open the link in a browser. No VPN client or LayerV account. For private shares, they follow the browser’s sign-in and access prompts.

Is qURL free?

Yes, it’s free. Share local apps and files without an account. For more shares, a dashboard and API access, explore the expanded capabilities and current limits.

Does my computer need to stay on?

Yes, when you share from it. Keep your computer awake and the app running while people use it. qURL shares from your machine instead of deploying a copy.

Go on. Show it off.

One less thing between
“I made this” and “try it.”

Yes, it’s free. No account needed for local sharing. Explore more capabilities

Share my app

Have a CRID? Open https://qurl.link/<CRID> in a browser. If someone asks you to open a CRID, give them that address exactly as it is.

Someone sent you one?

Paste the link you were sent. If all you have is an app’s 60-character ID, paste that and we’ll explain what it can and can’t do.

That’s an app’s ID, not a link. The ID alone doesn’t open anything.

If you published it yourself

            

            
Otherwise ask whoever sent it for a link. It takes them a second.

          

          
That doesn’t look like a link. A link starts with qurl.link/.

        

        
LayerV carries the traffic but does not check what people share. Open links only from people you trust.

        
    
          
  • It opens right here, in your browser. Nothing to install, no account.
    • 
          
  • Private shares need the publisher’s permission. Follow the browser prompts; keep email verification codes in the browser.
    • 
          
  • The part after # can contain a secret. Share access links only with the intended recipient. Didn’t open? Ask the sender for a fresh one.

The qurl CLI gives chosen visitors browser access to your running app. It stays invisible to everyone else, on your machine. Free, with no account needed.

        

          
Step 0 · Install (macOS)

          
brew install layervai/tap/qurl

        

        
Newest release: qurl 4.1.0.

        
Linux and Windows: grab the .deb, .rpm or archive from the CLI releases and put qurl on your PATH.

        

          
1 · publish with requests

          
qurl publish http://localhost:3000 --access review -o json

        

        
Check that the result is private and the consumer policy is review. Send the returned consumer address. Recipients verify their email and save a passkey in their browser.

        

          
2 · review requests

          
qurl access list_grants <id> -o json

        

        
Choose the pending request’s verified email. Use its decision ID and current version from this result. Email control does not prove legal identity.

        

          
3 · approve

          
qurl access approve <id> <decision-id> --version <current-version> -o json

        

        
Approve only the request you chose. Recipients never send you their email verification code. If the service cannot support this private policy, keep the app private and update before sharing.

 qURL for MCP
        
        
Connect to hosted MCP for resources already connected to qURL. To share an app on your computer, use local MCP below.

        
Hosted MCP · connect your account

        
Server URL: https://mcp.connector.layerv.ai/mcp. Use a qURL API key as the bearer token in a client that supports it. This option needs a LayerV account, with no local server to install. It manages resources through the API; it cannot reach localhost or files on your computer.

        
For Codex CLI, set QURL_API_KEY in the environment where you start Codex, then run:

        

          
Hosted MCP for Codex

          
codex mcp add qurl-hosted --url https://mcp.connector.layerv.ai/mcp --bearer-token-env-var QURL_API_KEY

        

        
Private resources need a qURL Connector. Creating a link for an existing public URL does not make its origin private.

        

          Local MCP · share from this computer
          
Install Node.js 22.12 or later and the qURL CLI, then add this to a client that supports local MCP servers. No LayerV account or API key is needed. Your private app stays on your computer, with access checked before a connection opens.

          

            
Local MCP client config

            
{
  "mcpServers": {
    "qurl": {
      "command": "npx",
      "args": ["-y", "@layervai/qurl-mcp@latest"]
    }
  }
}

          

          
Claude Desktop: claude_desktop_config.json. Cursor: .cursor/mcp.json. Restart your client, then ask: “Share the app on localhost:3000 privately with qURL.” For Codex CLI, run this in your terminal instead of adding JSON:

          

            
Codex CLI

            
codex mcp add qurl -- npx -y @layervai/qurl-mcp@latest

Your original stays on your Mac. qURL keeps it off public file hosts and checks the link before a recipient can connect. They view or download in a browser, with nothing to install.
