I Built a Complete CRM Using Only GitHub Repos and One AI Prompt Here's How

Gitstack — Mon, 11 May 2026 18:59:13 +0000

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.

Three Ways to Make Money on GitStack

1. Sell Your Build (Easiest)

Build any tool with GitStack → List it for $20-50 one-time → Other founders buy it → You keep most of it

2. Sell Managed Hosting (Recurring)

List your GitHub repo → Offer "I'll host this for you" → Charge $50-200/month → Passive income

3. Sell Support & Customization (Service)

Same repo → Offer priority support, custom configs, white-labeling → Charge per project

GitStack takes a small fee only when you make a sale. No listing fees. No monthly charges.👇
