- Verdict: **Serious undertaking** (38/100 vibecodeable)
- Estimated effort: 6+ weeks of full-time engineering

## Verdict

You can build a polished UI clone of the app catalog, but keeping the live Google and Meta ad-creative matching pipeline running at 5M-app scale requires significant engineering.

The front-end catalog explorer with multi-facet filters is straightforward to build with Next.js and Turso or Cloudflare D1. However, the true value of NicheMaps lies in its data pipeline—ingesting 5 million apps and programmatically indexing live ad creatives from the Google Ads Transparency Center and Meta Ad Library without breaking when those platforms update their DOM structures. A solo developer can build a personal prototype by mocking or selectively crawling a few hundred target apps, but duplicating the full 5M-app data lake and ad-matching engine is a heavy infrastructure undertaking.

### What you can't replicate

- The exact 5M+ app columnar dataset synchronized daily from app stores
- Robust, self-healing scrapers against upstream changes in Google and Meta ad transparency portals

## What it does

Market research and ad intelligence SaaS built for mobile app developers and indie founders, tracking 5M+ iOS and Android apps across Google Ads and Meta Ad Library.

### Core features

- Catalog explorer for 5M+ iOS and Android apps with exact result counts
- Multi-facet filtering (ad status, IAP monetization, installs, ratings, category)
- Ad intelligence integration pulling creatives from Google and Meta transparency hubs
- Traction & spend scoring (Zombie Hunter, sustained ad-spend rankings, niche velocity)
- Daily email digest pushing one ad-running app per day
- App comparison and shareable shortlists

## The business

### Pricing

- Free: $0 / forever
- Premium: $79 / month
Team size: Small, focused team.

## The hard parts

- Scraping and mapping Google Ads Transparency Center and Meta Ad Library creatives to specific mobile app bundle IDs at scale
- Maintaining a responsive columnar analytics store over 5 million app records with real-time facet counts
- Daily synchronization and data hygiene across millions of app store listings without hitting rate limits

## How to vibe code NicheMaps

### Prerequisites

- Node.js (free): Runtime for running Next.js and data ingestion scripts
- GitHub (free): Version control and CI/CD deployment connection
- Resend account (free): For sending the daily email digest

### Recommended AI tools

- Claude Code: Best-in-class agentic coding tool for scaffolding full-stack search indexes, UI tables, and scraper cron jobs
- Cursor: Ideal for iterative frontend component design and reviewing data-table diffs

### Stack

- Frontend: Next.js
- Backend: Next.js API Routes / Cloudflare Workers
- Database: Turso (SQLite at the edge for faceted app catalog search)
- Auth: better-auth
- Payments: Stripe
- Other: Resend, Firecrawl

### Hosting

- Cloudflare (Hosting Next.js frontend, API endpoints, and scheduled cron jobs for data sync): $0-5/mo
- Turso (Serverless SQLite database storing app catalog metadata and facets for fast queries): $0/mo

### Build guide

1. **Scaffold Project and Database Schema** — Initialize the Next.js project with Tailwind CSS, configure Turso for SQLite storage, and define the database schema for apps, categories, metrics, and ad statuses.

```
Initialize a new Next.js project with TypeScript and Tailwind CSS. Configure Turso (libSQL) as the database client. Create migration files for an 'apps' table (id, name, bundle_id, platform, category, rating, installs, iap_enabled, ad_status, created_at) and an 'ad_creatives' table (id, app_id, network, creative_url, run_start_date, days_running). Ensure proper indexes on category, ad_status, and installs to support fast faceted filtering.
```

2. **Build Catalog Explorer and Faceted Search UI** — Build the main catalog browsing dashboard with server-side filtering, sorting, pagination, and exact result counts matching NicheMaps' layout.

```
Build a responsive dashboard layout in Next.js mimicking the NicheMaps catalog explorer. Implement a sidebar with filters for Category, Min Installs, Min Rating, IAP Monopolization, and Ad Status (Running vs Not Running). Create a high-density data table that displays app metadata, install velocity, rating, and active ad counts with live server-side pagination and exact result counts queried from Turso.
```

3. **Build App Detail View and Ad Creative Inspector** — Create the app detail view modal or page showing metadata, growth charts, and embedded mock/live Google and Meta ad creatives with run durations.

```
Create an app detail page component in Next.js that loads when clicking an app row from the catalog. Display historical install and rating growth baselines using simple SVG charts. Add an 'Ad Creatives' section showing cards for each active ad pulled from Google Ads and Meta Ad Library variants, complete with days-running badges and direct links to transparency centers.
```

4. **Implement Sustained Spend & Zombie Hunter Views** — Add specialized analytical views for ranking apps by sustained ad spend duration and surfacing low-rated apps with high ad spend.

```
Implement dedicated discovery views in the sidebar: 'Sustained Spend' (ranking apps by how long their ads have run continuously) and 'Zombie Hunter' (filtering for apps with ratings below 3.8 that maintain active ad campaigns). Write optimized SQL queries in Turso to power these views instantly without client-side lag.
```

5. **Configure Daily Digest Email Cron Job** — Set up a scheduled Cloudflare Worker cron trigger to select one ad-running app daily and dispatch it via Resend to subscribed users.

```
Configure a Cloudflare Workers cron trigger that runs every morning at 8:00 AM UTC. The worker should query Turso for a random app currently running ads, format a clean HTML email template featuring the app's metadata and creative snapshot, and dispatch it via the Resend API to all confirmed subscribers in the newsletter table.
```

6. **Integrate Stripe Billing & Premium Paywall** — Add Stripe Checkout integration with trial periods and promotional pricing to gate ad-status filters and creative intelligence.

```
Integrate Stripe billing into the Next.js app to handle the Premium tier ($79/mo with an introductory $63.20 first-month promo and 7-day trial). Set up webhook endpoints to update user subscription status in the database. Protect API routes and UI filters so free users can browse metadata but cannot query ad-status filters or view raw ad creatives without an active subscription.
```

### Cost vs paying

**Starting costs (one-time):**

- Custom Domain: $12.00 / year
- Total: ~$12 one-time

**Ongoing costs (monthly):**

- Resend Email API: $0 / month (Free tier up to 3k emails)
- Total: ~$0 / month

- Paying for the SaaS instead: $79.00 / month
- Build time: 40-60 hours
- AI tool credits: $20.00 (Claude Pro / Cursor)
- Break-even: 0 months (Free to host personal clone vs $79/mo paid SaaS)
