Build Sites

Apps with several pages and pages anyone can open

A site is an app on the Site plan. On top of everything a Pro app has, a site can:

have several pages, each with its own address — for example /products, /contact or /account/orders;
make pages public, so people without an Operator account can open them;
set a title and description per page, which browsers, search engines and link previews show.

Plans at a glance

Plan	Daily cost	What you get
Free	none	The app itself, ERP.net data and AI
Pro	1 credit per day	Everything in Free, plus Operator Cloud: files, tables, secrets, web requests, triggers and procedures
Site	2 credits per day	Everything in Pro, plus Pages: extra page addresses, public access and custom domains

Usage adds to the daily cost.

When you need a site

Choose Site when the app must reach people outside your team, or needs separate addresses:

Landing page for a product or a campaign.
Public contact or order form that customers fill in without signing in.
Product catalog showing live ERP.net prices and stock.
Shareable dashboard — for example delivery status a partner can open from a link.
Several distinct screens that people bookmark or share, such as /report and /settings.

You do not need a site for an internal tool that only signed-in colleagues use on one screen. Pro (or Free, if you don't need storage) is enough.

Examples

"A stock dashboard for my warehouse team" → Pro.
"A page where customers check their order status with an order number" → Site.

What a public page can and cannot do

A visitor of a public page is not signed in. So a public page cannot use:

your ERP.net connection;
the app's tables or stored files;
secret values.

Anything it shows from a server comes through a web request marked Public. A public request runs on the server with its own stored login (for example an ERP.net service user), kept under Secrets. The App Builder sets these up for you — you only type in the login values.

Example: a public catalog page calls a public request "Get products", which logs in to ERP.net with a service user and returns names and prices only.

Mark a request Public only when its result is safe for anyone to see.

Switching an app to Site

Open the app in the App Builder.
Go to Properties.
In the plan card, choose Upgrade on Site.

The Pages tab appears next to Cloud.

Downgrading from Site removes the Pages tab and turns every public page, including a public Home page, back to non-public.
