Build a Real Estate Map CRM with Claude Code in 10 Minutes

What We're Building

By the end of this tutorial, you'll have a fully functional real estate CRM that includes:

• Interactive map showing all your property deals with color-coded markers
• Deal management - add, edit, and track properties through your pipeline
• Dashboard analytics - total deals, active deals, closed deals, portfolio value
• Filtering & search - find deals by status, property type, price range, or location
• CSV export - download your data anytime
• Responsive design - works on desktop and mobile

The best part? You don't need to write a single line of code yourself. Claude does all the heavy lifting.

Prerequisites

Before we start, make sure you have:

• Claude Code installed - If you haven't already, grab it from claude.ai/code
• A DartUp account - Sign up free at dartup.dev (your first deployment is free!)
• Node.js installed - Version 18 or higher

Step 1: Create Your Project

First, let's create a new folder for our project and open Claude Code in it.

This opens up Claude Code in your new project directory. Now the fun begins!

Step 2: Tell Claude What to Build

Here's where the magic happens. Just describe what you want in plain English. I like to be specific about the features I want, but you can start simple and iterate.

Here's the prompt I used:

Build me a real estate CRM web app called "Pinpoint" with these features:

1. Interactive map showing property deals using Leaflet
2. Sidebar navigation with Dashboard, Map View, All Deals, Active, Closed, and Reports
3. Dashboard with stats cards: Total Deals, Active Deals, Closed Deals, Portfolio Value
4. Deals table with columns: Address, Price, Type, Status, Date
5. Property types: Residential, Commercial, Industrial, Land
6. Deal statuses: Active, Pending, Closed (color code the map markers)
7. Add Deal modal with form fields
8. Search by address/city
9. Filter by status, type, and price range
10. Export to CSV button
11. Clean, modern black and white design
12. Use localStorage to persist deals

Make it a static HTML/CSS/JS app so it's easy to deploy.

Hit enter and watch Claude work. You'll see it thinking through the architecture, creating files, and building your app piece by piece.

Step 3: Test It Locally

Before deploying, let's make sure everything works. You can just open the HTML file directly, or spin up a quick local server:

Open http://localhost:3000 in your browser. Play around with it! Add some deals, try the filters, check out the map. If something's not quite right, just tell Claude what to fix.

Step 4: Deploy to DartUp

Now for the exciting part - let's put this thing live! If you haven't already, sign up for a free DartUp account and grab your API key from the dashboard.

First, tell Claude your API key (it'll remember it for future deployments):

My DartUp API key is: jd_xxxxxxxxxxxx

Remember this for future deployments.

Now, the moment of truth. Just say:

Deploy this to DartUp

Claude will zip up your project, upload it, and DartUp will have it live in seconds:

That's it! Your real estate CRM is now live on the internet. Share the link with your team, access it from your phone, or just show it off to your friends.

Customizing Your CRM

The beauty of building with Claude is that iteration is a breeze. Want to add features? Just ask:

• "Add a notes field to each deal"
• "Change the color scheme to blue and white"
• "Add a chart showing deals closed by month"
• "Make the markers cluster when zoomed out"

After making changes, just say "deploy this again"and your updates go live.

Taking It Further

This is just the beginning. Here are some ideas to level up your CRM:

• Add authentication - Make it multi-user with login/signup
• Connect a database - Switch from localStorage to a real backend
• Email notifications - Get alerts when deals change status
• Property details - Add photos, documents, and contact info
• Mobile app - Ask Claude to add PWA support for offline access

The point is: you now have a working foundation that you built in minutes, not months. And it's running live on a real URL that you can share with anyone.

Wrapping Up

We just built a complete real estate CRM with interactive maps, deal tracking, analytics, filtering, and export functionality. And then deployed it live. All in about 10 minutes.

This is what building software looks like in 2026. No wrestling with frameworks, no debugging CSS for hours, no configuring deployment pipelines. Just describe what you want, and watch it come to life.
