LeadFlow — Lead Generation & Email Enrichment Platform

A unified platform for three lead-scraping pipelines with email enrichment via Anymailfinder.

Tech Stack

Next.js 16 (App Router) + TypeScript
SQLite via Prisma 7 + better-sqlite3
shadcn/ui + Tailwind CSS
Anymailfinder API v5.1 — email enrichment (bulk JSON + individual search)
Vayne API — LinkedIn Sales Navigator scraping
Apify — Google SERP scraping

Setup

1. Install dependencies

cd leadflow
npm install

2. Configure environment

Copy .env.local.example to .env.local:

cp .env.local.example .env.local

Edit .env and .env.local:

APP_ENCRYPTION_SECRET=your-32-character-secret-here!!

3. Run database migration

npx prisma migrate dev

4. Start the app

API Keys — Where to Get Them

Go to Settings in the sidebar to enter and save credentials. All keys are AES-256 encrypted before storage.

Anymailfinder

Sign up at anymailfinder.com
Account → API → copy your key (format: starts with your account prefix)
Pricing: 2 credits/valid decision maker email, 1 credit/person email
Bulk API charges only when downloading results

Apify

Sign up at apify.com
Console → Account → Integrations → API tokens
The app uses the apify/google-search-scraper actor (pay-per-event)

Vayne

Sign up at vayne.io
Dashboard → API Settings → generate token
Connect LinkedIn in the Vayne dashboard — Vayne manages the LinkedIn session on their end
No need to manually export cookies

Pipeline Workflows

Tab 1 — AirScale → Email

Export companies from AirScale as CSV
Upload → map domain column
Select decision maker categories
Start Enrichment → bulk API runs asynchronously
Export CSV/Excel

Tab 2 — LinkedIn Sales Navigator → Email

Build search in Sales Navigator, copy URL
Paste URL + set max results → Start Scrape
Vayne scrapes profiles (polls until done)
Select profiles → Enrich with Emails
Export results

Tab 3 — SERP → Email

Enter search term (e.g. "Solaranlage Installateur Deutschland")
Set country/language, enable social filter
Select decision maker categories
Start → Apify scrapes Google, domains extracted, then bulk enriched
Export results

How Anymailfinder Bulk Works

All domains submitted as one POST to /v5.1/bulk/json
Poll status every 5s until completed
Download results once (credits charged at download, not submission)
Speed: ~1,000 domains per 5 minutes

Database

SQLite at ./leadflow.db. Inspect with:

npx prisma studio

Troubleshooting

Issue	Solution
"API key not configured"	Add key in Settings
Job stuck at "running"	Check server console (`npm run dev` terminal)
Prisma errors on build	Run `npx prisma generate && npm run build`
