How I Make $100/Month from Open Source (Step-by-Step Guide)
Here is exactly how I make passive income from open source Node.js packages, without a paid product or customers.
The Strategy
My approach is simple: build useful CLI tools, publish them on npm, and monetize through affiliate links and tips.
Step 1: Build Tools Developers Actually Need
I focused on 3 pain points:
- Security scanning for .env files (dotguard)
- Git commit history visualization (gitpulse)
- Code snippet management (snippetx)
Step 2: Optimize npm Package Pages
Each package has:
- Clear README with install instructions
- Cross-promotion between packages
- Affiliate links to hosting providers
- Ko-fi tip button
Step 3: Write SEO Articles
I publish Dev.to articles targeting developers searching for:
- How to deploy Node.js apps
- Git security best practices
- Open source monetization
Step 4: Build an Audience
The loop: npm packages -> README links -> Dev.to articles -> affiliate clicks
Hosting Recommendation
If you need affordable cloud hosting, check out DigitalOcean. Their $6/mo droplets are perfect for Node.js apps and they offer a free trial.
