Every application you build in Saasio is composed of two fundamental building blocks. Understanding the distinct role of each is the key to creating a powerful, full-stack application.
Pages: The User Interface
Pages are what your users see and interact with—like a homepage, a
dashboard, or a profile section. They are the visual front-end of your
application.
API Routes: The Backend Logic
API Routes are the invisible backend. They are server-side endpoints
that handle data, process requests, and communicate with your database or
other services.
Pages: Building Your User Interface
Your project’s pages form the map of your application. When you create a new project, Saasio automatically includes two essential, non-deletable pages:- Home (
/): The default page users land on when they visit your main URL. - 404 (
/404): The “Not Found” page shown when a user tries to access a URL that doesn’t exist.

1. Navigate to the Pages Tab
In the left panel of the Visual Editor, ensure the Pages tab is selected. This area lists all the pages in your project.

2. Create a New Page
Click the
+ icon at the top of the pages list. This action opens a
prompt to name your new page.3
3. Enter the Page Name
Provide a clear, simple name for your page. This name will automatically become its URL path. For example:
- A page named
pricingwill be accessible atyour-domain.com/pricing. - A page named
about-uswill be accessible atyour-domain.com/about-us.

Creating a new page in the Saasio editor by providing a name.
Once created, you can click on any page in the list to load it onto the
central canvas and begin designing its layout and content.
API Routes: Powering Your Backend
API Routes are your application’s connection to the server. They are essential for any task that requires secure or private logic, such as fetching user data, processing a payment, or connecting to another company’s API. Here’s how to create one.1
1. Navigate to the API Routes Tab
In the left panel, switch from “Pages” to the API Routes tab.

2. Create a New API Route
Click the
+ icon to open the API route configuration dialog.3
3. Define the Route Path and Method
Every API route needs two critical pieces of information:
- Path Name: The unique URL for your endpoint (e.g.,
/users,/products). This is the address that your application (or other services) will call. - Method: The HTTP method the route will respond to. This defines the type of action the route performs:
GET: Retrieve Data. Use this method to read or fetch information from your database or an external service.POST: Create New Data. Use this method to add a new record to your database or send data to an external service.PUT: Update Existing Data. Use this method to modify a record that already exists.DELETE: Remove Data. Use this method to permanently remove a record from your database.
