Put your Codex app online.

Right now it runs on localhost, which is your computer and nobody else’s. Connect Codex once, then one sentence puts it at an address anyone can open. No more localhost.

Connect once

A short block in its settings. Then never again.

Sign in at app.tiniest.cloud, open Connect, and pick Codex.

Codex
  1. Connect shows the block, filled in.
  2. Paste it into Codex. It adds it to its own settings.
  3. Restart Codex.
[mcp_servers.tiniest-cloud]
url = "https://app.tiniest.cloud/mcp"
http_headers = { "Authorization" = "Bearer <your key from Connect>" }
Connect fills in your key.

Then say the words.

In Codex, in the chat where you built the app.

Plain answers

About Codex and Tiniest Cloud.

How do I put a Codex app online?

Paste the short settings block from Connect into Codex once and restart it. Then say “put this on Tiniest Cloud” and Codex uploads the app and gives you its address.

Where does the block go?

Into Codex’s own settings. Paste it into the chat and Codex adds it for you; the block names the address and carries your key, and Connect fills both in.

Do I need to know how to code?

No. You describe the app, your agent builds it, and one more sentence puts it online. The only command you will ever see is the one line that connects your tool, and Connect fills that in for you.

Is it free?

Yes, to start. Five live apps with sign-in, saving and AI included, forever. Personal is $10 a month for unlimited apps and your own domain.

Do the people who use my app pay?

Never. They open your link and sign in with an email link or their Google account. Only the person who put the app online has a plan.

Another tool?

Same sentence, every agent.
