Return format

Returns the live URL, deployment ID, and slug:

Deployed successfully!

URL: https://my-waitlist.invoker.page
ID: dep_abc123
Slug: my-waitlist

Example

User prompt:

Deploy a waitlist page for my app called Acme at acme-waitlist

What Claude does:

1. Calls use_template with template: "waitlist" to fetch the base HTML.
2. Customizes the HTML with "Acme" branding.
3. Calls deploy with the modified HTML and slug: "acme-waitlist".
4. Returns the live URL https://acme-waitlist.invoker.page.

Notes

• Form action placeholder: Use as the action attribute on any <form> element. This is replaced with the real submission endpoint at deploy time. Forms without this placeholder will not have their submissions captured.
• Slug rules: Slugs must be lowercase and may contain hyphens. If the requested slug is already taken, the deploy will fail with an error.
• Free plan limit: Free accounts can have up to 5 active deployments at a time. Use teardown to delete a deployment and free up a slot.
• No build step: The HTML is served as-is. There is no bundler, preprocessor, or framework involved. Inline your CSS and JavaScript, or link to external CDNs.
