Try while without an account
With no account and no card, your agent deploys your app as a trial, in one request. You keep it by creating your account.
Updated November 3, 2026.
Step 1: Give your agent these instructions
Open your agent in your app’s folder, and paste these instructions into it:
Read while.sh/agents, then deploy my app with while.Your agent connects to while’s trial MCP server, https://app.while.sh/essai, with no account and no credentials. It then deploys your app and gives you its address.
If you use Claude, ChatGPT or Mistral Vibe in the browser, first add a custom connector at https://app.while.sh/essai, with no authentication. Then ask the agent to deploy your app.
Step 2: Open your app
Your app is live over HTTPS, at the address your agent gives you.
With Claude, ChatGPT or Mistral Vibe in the browser, your agent also gives you a confirmation link. Open it within the next few minutes: that’s how while checks that a person is behind the trial, and without that visit, the trial stops.
Step 3: Keep your app
To keep your app, open the claim link your agent gives you, and create your account. The Free plan is €0, and you only pay for what your apps use.
Your agent then connects to while’s MCP server, https://app.while.sh/mcp, and carries on with your account.
What a trial deploys
A trial deploys a simple app, with its database if it has one. If your app needs more, your agent tells you, with the link to create your account.
