How to Build a Simple Frontend for n8n Workflows Using Firebase

From JOHNWICK

Building AI automations and AI agents with n8n is one of the best no-code/low-code methods out there. You can integrate your favorite developer tool and build robust automations and agents in minutes. However, there is one problem: n8n does not have a frontend feature where you can show a user interface to interact with the agent or workflow outside the n8n console. Those who want a fully low-code option are often discouraged because they now have to hire a frontend developer to build a UI for them or learn frontend development skills to do so. Well, not anymore. Firebase Studio makes creating user interfaces for the n8n backend simple and efficient. In this guide, we will explore Firebase Studio and build a simple full-stack automation tool using n8n and Firebase Studio. To get started, let’s briefly take a look at Firebase Studio.

Overview of Firebase Studio

Firebase Studio is an agentic cloud-based development environment that helps you build and ship production-quality full-stack AI apps. It’s like Lovable but has several other features due to Google’s wide developer ecosystem of tools.

With Firebase Studio, you can:

  • Generate frontends via chat prompts.
  • Connect to backends through REST APIs or webhooks.
  • Edit code manually if needed.

In practical terms, this means that the backend logic designed in n8n can be made accessible to end users through Firebase Studio interfaces. A simple form, dashboard, or data-entry screen can be created in minutes, which gives workflows a face to interact with So, since we have the introductions out of the way, let’s begin setting up n8n and connecting n8n to Firebase.

Configuring the n8n Workflow

We’d use a newsletter subscription workflow. This workflow is simple but enough to show how to integrate Firebase Studio and n8n. The workflow will do the following:

  • Capture the email address submitted by the user.
  • Save the email to a Google Sheet.
  • Send a welcome message via Gmail to confirm subscription.


The sample newsletter n8n workflow To begin, head over to n8n and login. Download the JSON file for this workflow here and import it into your n8n console. Once you have imported the JSON file to n8n, configure the Google Sheets and Gmail nodes with the relevant account credentials.

The webhook node settings page The next step is to adjust the webhook settings. Open the Webhook node, and you will see the page above. You need to configure 3 important components, as highlighted in the image above.

  • The Webhook URL: You can decide to set the URL to test or production, but since we are just playing around, setting it to “Test URL” is preferred.
  • The HTTP method: Set this to “POST”, since we are expecting data to be sent into the workflow.
  • Path: You will notice that the default path is lengthy and ugly, so rename it to something easy, like “email”.

Once you are done with these setups, head over to Firebase Studio to finish up with a user interface.

Connecting n8n to Firebase Studio

Head over to Firebase Studio and Login or create an account if you do not have an account already. Once you have created an account, you should see this image below, meaning you’re ready to get started!

Firebase Studio Creator page Next, add the following prompt to generate the UI for the newsletter page: Create a sleek, dark-themed landing page for my n8n-focused newsletter, including: A black background with a matt gradient. Center-aligned layout with modern typography. Black And White Theme Headline: 
“Get 1 Free n8n Automation Every Week”

Subheadline:
“Stay ahead of the curve with weekly workflow drops, tips, and updates on the latest from the n8n ecosystem.”

Form field: Email (required)

CTA Button: “Subscribe”

Additional design elements: No navbar, no footer links

Clean spacing and visually balanced Everything is packed in the center

This landing page should feel personal, trustworthy, and modern, focused solely on collecting emails for the newsletter.

Once you have added the prompt, click on the “Prototype with AI” button and wait a while for Firebase to generate the UI. When Firebase is done, it shows you what it has done before completing the UI, as seen in the image. Once you are satisfied with the UI specs, you can click on the “Prototype this App” button.

UI preview page on Firebase Studio You’re good to go! You should see the UI design that Firebase generated.


UI design generated by Firebase Studio Next, we would add the REST endpoints so that n8n receives the email after someone subscribes. Head over to the webhook setting on n8n and copy the webhook URL, then add this prompt using the chat interface:

“Create a simple subscription form with one input field for email and a submit button. On submit, send a POST request to my n8n webhook at <your-webhook-url>.” Now, finally.. We have to test the entire system. Go to n8n and start the workflow. Then, return to Firebase and enter an email address in the email box.

As seen in the n8n console below, the workflow executed successfully, and you should receive an email, and the Google sheet will be updated.

Successful n8n workflow execution Congrats and well done for making it this far. As you have just seen, Firebase Studio is a great companion for n8n backends. This guide has only introduced the basics, so take time to experiment to explore customization of the UI and POST/GET requests with more complex workflows.
