I needed a CRM. I had $0 budget. So I built one with GitHub repos and AI.
Last month my close friend needed a CRM for my startup. HubSpot wanted $99/month. Salesforce wanted $300/month.
So I did something crazy: I built one using only free GitHub repos and a single AI prompt.
Here's the exact stack GitStack gave me:
| Tool | What It Does | GitHub Stars |
|---|---|---|
| Supabase | Database + Auth | 78K |
| n8n | Workflow automation | 46K |
| Metabase | Analytics dashboards | 41K |
| Cal.com | Scheduling | 32K |
Total cost to run: $5/month on a VPS
vs HubSpot/Salesforce: $99-300/month
That's $3,600+/year saved on ONE tool.
But here's the real magic — The Master Prompt
GitStack didn't just give me the tools. It gave me one copy-pasteable prompt that I fed into Cursor.
That prompt built:
- Database schema
- Authentication system
- API endpoints
- Frontend UI
- Deployment config
From "I need a CRM" to "It's live" in 2 hours.
Total spend: $5/month. Not $300.
This isn't just for CRMs
Build It Once, Sell It Forever
Here's what most people miss:
I built that CRM for $5/month. But I can also sell it on GitStack's marketplace to other founders who need the same thing.
How it works:
- I used GitStack to build a working CRM (free open-source stack + one AI prompt)
- I polished it, branded it, made it deploy-ready
- I listed it on GitStack Marketplace for $30 one-time purchase
- Other non-technical founders buy it → deploy in one click → save $99/month on HubSpot
They get: A working CRM for $30 one-time (vs $1,200/year HubSpot)
I get: $30 every time someone buys
GitStack gets: A small transaction fee
No coding required for the buyer. No ongoing SaaS bill. One purchase, own it forever.
