The verdict: can you vibe code Apollo.io?
Keep paying for Apollo; its 240M+ contact database and email deliverability infrastructure are impossible for a solo developer to replicate.
While you can easily build a CRUD interface with a few hundred mock records and an AI email writer, the true value of Apollo lies in its massive proprietary B2B contact database, continuous scraping pipelines, and battle-tested email deliverability infrastructure. Trying to replicate the data scale and inbox reputation management alone is a multi-year engineering undertaking.
Estimated effort: 6+ months of full-time work just to build a brittle fraction of the data pipeline
What you can't replicate
- Living database of 240M+ verified contacts and 30M+ companies
- Inbound data contributor network of 2M+ sources
- Whitelisted IP pools and automated SPF/DKIM/DMARC deliverability guardrails
- Enterprise compliance moat (SOC 2, ISO 27001)

Build guide
01Project Scaffolding and Database Setup
Initialize the Next.js project with Tailwind CSS, shadcn/ui, and configure Neon Postgres with better-auth.
Create a new Next.js project using the App Router, TypeScript, Tailwind CSS, and configure shadcn/ui components. Set up better-auth with email/password authentication connected to a Neon Postgres database using Drizzle ORM. Create database schemas for users, contacts (with fields for name, title, company, email, phone, location, and industry), companies, and email_sequences.02Prospect Database Search and Filter UI
Build a multi-facet filtering interface to query contacts and companies stored in the database.
Build a dashboard page mimicking a B2B search engine with a sidebar containing multi-select filters for job title, seniority, company size, industry, and location. Implement a server-side search query builder in Next.js that executes parameterized SQL queries against Neon Postgres with pagination and sorting. Display results in a rich data table with checkboxes for bulk selection.03AI Email Assistant Integration
Integrate the Anthropic API to generate personalized cold outreach emails based on prospect firmographics.
Implement an API route that accepts a contact ID and a prompt template, fetches the contact and company details from Neon Postgres, and calls the Anthropic API (Claude 3.5 Sonnet) to draft a hyper-personalized cold outreach email. Build a modal UI in the dashboard that displays the generated draft and allows the user to edit and save it.04Email Sequencing Engine & Resend Integration
Build a lightweight sequence scheduler that queues steps and dispatches emails via Resend.
Create database tables and backend logic for email sequences with multi-step delays. Implement a background cron job using Vercel Cron that checks for pending sequence tasks, renders email templates with contact variables, and dispatches them via the Resend API. Track sent status, opens, and replies in the database.05Dashboard Analytics and Polish
Add performance overview charts and clean up UI states.
Add analytics widgets to the main dashboard showing total sequences active, emails sent, open rates, and replies using lightweight charting components. Ensure all UI states handle loading, empty datasets, and error boundaries gracefully.
