Publishing Your Softr App

How to publish your Softr app.

Publishing the application pushes all your changes to the web instantly. Your application and all pages in Studio are not visible to anyone before you publish and share a link.

By default, your application gets assigned a random subdomain: https://<randomname>.softr.io and is published to the Staging environment of Softr (not visible to anyone except you). You can view domain and publication status info by clicking the Publish button on the top navigation bar.

When you want your application to be visible to anyone on the web, you need to publish your changes to the Live environment and share a link. You can do this by clicking the Publish button inside the pop-up.

After publishing, you can share the public subdomain link to anyone (e.g. “https://ninfa906.softr.io” from the example above). In the next section, you’ll find out how to personalize your subdomain link.

Previewing your Softr app

Softr also has an option to Preview the app before publishing to see how it works and what it looks like. You can even preview the app as specific users of your application to see exactly what a user or group of users will see on their side. To preview your Softr app, click on the Play icon in the upper right of Softr Studio.

With the preview open, you can use the dropdown in the upper left to search and select the user you would like to preview as. You can also generate a shareable preview link using the Get shareable link button in the upper right of the preview window so that others can preview your application if needed. Use the device selector in the top-middle of the screen to preview your app on different device screen sizes.

Previewing with QR Code

You can also easily preview the tablet and mobile versions of your app by scanning the QR code that is available when previewing those devices in the Softr Preview. Simply select tablet or mobile view at the top of the preview window and scan the QR code with your device.

Alternatively, you can also email a link to preview the app to your Softr account email.

Custom Subdomain

You can customize your public subdomain that is assigned randomly (https://<randomname>.softr.io) to “https://application-name.softr.io”. You can do this from the Publish dropdown as shown below.

  • fetchRead one page in full, as Markdown.
  • list_pagesSee every page in this documentation.

Query these docs over HTTP

The same tools also work as plain web requests. Use this for scripts, or for any tool that does not support MCP. There is one endpoint per tool. Arguments go in the query string, and the answer comes back as JSON.

https://docs.softr.io/api/docs/search?query=custom+domain

Read the OpenAPI description. It is built from the same definitions as the tools, so it always matches what the endpoints do.

Read these docs as Markdown

Add .md to any page URL to get its Markdown source. You can also send the headerAccept: text/markdown to the page URL itself.

To read the whole documentation in one file, open llms-full.txt. For a short index of every page, open llms.txt.
