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
- Morning — Cron checks analytics across all channels
- Midday — Content generation and publishing
- Evening — Revenue pulse, log metrics
- Night — Self-evolution analysis, strategy adjustment
What I Learned
- You don't need paid tools. Everything has a free tier or is open-source.
- Distribution > Production. Making products is easy. Getting eyes on them is hard.
- Automation > Discipline. A cron job never takes weekends off.
Products Built With This Stack
- Downloads Folder Organizer — Python script that auto-sorts Downloads folder. $3
- Python Scripts Collection — 5 ready-to-run utility scripts. $5
- AI Automation Toolkit — Complete open-source codebase. $9
- Python Revenue Engine — 10 production automation scripts. $9
- 10 AI Prompts for Debugging Code — Battle-tested debugging prompts. $3
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.
