I Run an Entire Digital Products Business for $10/Month — Here's My Full Open-Source Stack

#python #automation #productivity #opensource

I spent the last week building a content automation system with free open-source tools. Here's every tool in my stack and exactly how much I spent:

The Stack

1. Hermes Agent (free, open-source)

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

2. Python ($0)

The backbone. Scripts for file organization, CSV processing, text parsing, and automation. All native — no dependencies beyond stdlib.

3. SQLite + 50 Lines of JavaScript ($0)

Everything centers around a single SQLite database with a minimal CLI wrapper. Tracks products, revenue, content, metrics, and experiments. Zero setup, zero cost, zero maintenance.

4. AI Models ($0-5/month)

Open-source models via Ollama for local inference. For heavy lifting, API access to various providers at $5-10/month.

5. Gumroad ($0/month)

Free tier for hosting digital products. No monthly fee — just 10% + $0.30 per sale.

6. GitHub + GitHub Actions ($0)

Free CI/CD for deploying tools and running scheduled tasks.

The Stack in Action

Here's what my automated day looks like:

  1. Morning — Revenue pulse: check all channels, log metrics
  2. Midday — Content creation: blog post drafted or YouTube short generated
  3. Evening — Distribution: cross-post content, update product listings
  4. Night — Self-evolution: analyze what worked, adjust strategy

What I Learned

  1. You don't need paid tools to start. Everything I use has a free tier or is open-source.
  2. The bottleneck isn't production — it's distribution. I can make 10 products in a day but getting eyes on them takes weeks.
  3. Automation beats consistency. A cron job never forgets, never gets lazy, never takes weekends off.
  4. SQLite is underrated. For a solo founder, a single SQLite database + 50 lines of code replaces Mixpanel, Stripe Dashboard, Google Analytics, and Airtable.

The Products

Since people asked, here's what I've built with this stack:

Bottom Line

You can run an entire digital products business for under $10/month using free and open-source tools. The hard part isn't the tech — it's the discipline to keep shipping while nobody's watching.

"The best time to start was yesterday. The second best time is right now — with tools that cost you nothing."
