I Can't Code — But I Built a Full Marketing Automation Platform with AI (and Open-Sourced It)

#opensource #react #supabase #ai

I'm a solo entrepreneur from India. I have zero coding knowledge — I literally don't know the difference between a function and a variable.

But last month, I open-sourced a full-stack marketing automation platform that I built entirely with AI.

The Problem

I run a coaching business. My clients are coaches and consultants who need marketing automation — email sequences, payment tracking, lead management. The tools that do this (HubSpot, ActiveCampaign, ConvertKit) cost $200-800/month. Most solopreneurs can't afford that.

What I Built

Claude Coach Kit — a free, open-source alternative:

📧 Multi-step email nurture sequences with auto-enrollment
💰 Razorpay payment tracking with webhooks
📊 UTM attribution — trace every payment back to the exact ad creative
📋 Google Sheet sync for lead management
📈 9-page analytics dashboard
🔄 Payment recovery automation

Tech stack: React 18 + Supabase + TailwindCSS + Edge Functions

The Crazy Part

Every single line of code was written through conversations with Claude. I'd describe what I needed, Claude would build it, I'd test it, and we'd iterate.

The entire project — 78 files, 20+ pages — was built this way.

It's now serving real clients processing real payments.

Architecture

Ad Platform (Meta/Google)
    ↓ (UTM parameters)
Landing Page
    ↓ (visitor tracking)
Supabase Edge Function (track-visitor)
    ↓ (stores UTMs + visitor ID)
Razorpay Payment
    ↓ (webhook)
Supabase Edge Function (razorpay-webhook)
    ↓ (matches visitor → payment)
Email Automation (SMTP/Resend)
    ↓ (nurture sequences)
Analytics Dashboard (React)

Why Open Source?

Because every coach and solopreneur deserves access to enterprise-grade marketing tools, regardless of budget.

HubSpot charges $800/month. ActiveCampaign charges $200/month. Claude Coach Kit charges $0. Forever.
