Customize your Map Portal with App Builder

With our App builder, you can easily customize your custom Map Portal according to your needs. You can create a user-friendly interface all by yourself, easily and quickly, without any programming knowledge.

Firstly, you need to install Map Portal through GIS Cloud Manager. Learn more about it here.

You can also edit the custom apps by adding adequate advanced options in the Advanced tab. And if you’re familiar with JavaScript and JSON, you can access the core app file (app.json), edit it additionally, and add more complex features through the text file as well. This way, you can customize your Map Editor and Map Viewer custom apps as well.

To sum it up – it is possible to add your personal logo, custom color, tools, buttons, panels and many more.

Open app builder

To start the app builder open your custom app and add /builder in the URL bar e.g.,

Log in with your GIS Cloud credentials. The App builder interface will open from the left side.

The Preview button is used to review changes made on a custom app before they are published to other users or the public. Changes will be saved after hitting the Save button.

After all the changes are made and saved, delete the ‘/builder‘ finish, from the app URL to exit the App Builder.

Options to customize your app


Select default map from the drop down menu. This map will open by default when the app is refreshed.
