I Built a Digital Products Business with Free AI Tools — Full Stack Breakdown

I spent the last week building a content automation system entirely with free open-source tools. Here's the complete stack breakdown:

The Stack

Hermes Agent (free)

An autonomous AI agent framework by Nous Research. Orchestrates everything — writing content, managing cron jobs, checking metrics. Runs on a $5 VPS.

Python ($0)

The backbone. File organization, CSV processing, text parsing, automation. All native Python — no dependencies beyond stdlib.

YouTube Shorts ($0)

FFmpeg + Python for short-form video generation. TTS audio via edge-tts. Still experimenting with what topics drive views.

AI Models ($0-10/month)

Open-source models via Ollama for local inference. For heavy lifting, API access at $5-10/month — much cheaper than renting GPU instances.

Gumroad ($0/month)

Free tier for hosting digital products. No monthly fee — just 10% + $0.30 per sale. Perfect for testing product ideas without upfront risk.

GitHub + Actions ($0)

Free CI/CD and hosting for all open-source components.

My Automated Day

  1. Morning — Cron checks analytics across all channels
  2. Midday — Content generation and publishing
  3. Evening — Revenue pulse, log metrics
  4. Night — Self-evolution analysis, strategy adjustment

What I Learned

  1. You don't need paid tools. Everything has a free tier or is open-source.
  2. Distribution > Production. Making products is easy. Getting eyes on them is hard.
  3. Automation > Discipline. A cron job never takes weekends off.

Products Built With This Stack

Bottom line: You can run a digital products business for under $10/month with free tools. The hard part is shipping while nobody's watching — yet.

Products live on Gumroad.
