# Build a Waitlist Page in Lovable with Sheet Ninja

## Lovable and Sheet Ninja

Lovable is one of the fastest ways to go from idea to a real, working web app. Describe what you want, and within minutes you've got something that looks and feels production-ready.

But when it comes to storing data, things get awkward quickly. **Lovable's built-in options are either overkill for a simple project or require backend knowledge most vibe coders don't have yet.**

Sheet Ninja changes that. You get all the speed and polish of Lovable for your UI, with Google Sheets handling your data - somewhere you can actually see it, edit it, and share it without touching any infrastructure.

## The use case

You have an idea and you want to know if anyone actually cares before you build it. A waitlist page does one thing: **captures emails from people who want in**. You collect them, you own them, and you can start talking to your future users tonight.

## Here’s how:

#### 1. Set up your Google Sheet

Create a new [Google Sheet](https://docs.google.com/spreadsheets/d/1YWe0gO_fBncby3kK6RuixwjSgr5-uJE45urFrPT-S_U/edit?usp=sharing) and add these column headers in Row 1:

| name | email | created_at |
| --- | --- | --- |

#### 2. Create your Sheet Ninja API

Then go to sheetninja.io, connect your Sheet, and copy your API endpoint URL. Here’s the [Quickstart guide](https://docs.sheetninja.io/quickstart#3-simple-steps) if you need a reminder.

Make sure to enable the right endpoints. For this use case we’ll just need ‘Add Row’ because we’re adding a row to the spreadsheet.

That's your database, your CRM, and your export tool - all in one place you already know.

#### 3. Build it in Lovable

Open a new Lovable project and paste this prompt into the AI:

8--- DATA ---
9The data lives in a Google Sheet connected via Sheet Ninja. My Sheet Ninja base URL is: <<YOUR_ENDPOINT>>.
10The sheet has these columns: email, name, created_at
11
12--- HOW IT WORKS ---
13- The page has a headline, a short description, and a signup form
14- The form asks for name and email
15- When someone submits, save their name, email, and current date/time automatically
16- After submitting, show a confirmation: "You're on the list — we'll be in touch"
17- Don't let the same email sign up twice — show a friendly message if they try
18
19--- KEEP IT SIMPLE ---
20- No login needed - Show a loading state while the form submits
21- Show a friendly error if something goes wrong
22- Clean, minimal design
23— the form should be above the fold
```

Replace <<YOUR_ENDPOINT>> with your Sheet Ninja URL and hit send. Lovable builds the whole thing.

## What you get

And your sign ups? They’re already in your Google Sheets:

## Why Google Sheets?

Every signup lands as a row in your Sheet the moment it happens. **You can see your list grow in real time, filter by date, and copy emails into any tool you already use:** without exporting, importing, or paying for a CRM you don't need yet.

Most waitlist tools lock your data inside their platform. **With Sheet Ninja, the data is yours from day one.**

Ship the page tonight. When you're ready to launch, your list is already waiting.

## DON'T OVERTHINK IT. JUST SHIP IT.

You have a dozen ideas in your notes app. Pick one. Grab a Sheet. Go live tonight.
