How to Monetize Open Source Projects
You built something useful. People use it. Here is how to make money from it.
The Reality of Open Source
- 90% of open source projects make $0
- Top 1% make $100K+/year
- Most maintainers burn out without funding
- Monetization is possible but requires strategy
Model 1: Open Core
How it works:
- Core product is free and open source
- Premium features are paid
- Hosted version is paid
Examples:
- GitLab (free CE, paid EE)
- WordPress (free core, paid hosting)
- Supabase (free self-host, paid cloud)
Best for:
- Infrastructure tools
- Developer tools
- Products with clear free/paid line
Revenue potential: $10K-1M+/year
Model 2: SaaS Hosting
How it works:
- Software is free to self-host
- You charge for managed hosting
- Convenience is the value
Examples:
- Plausible Analytics
- PostHog
- Cal.com
Best for:
- Complex software (hard to self-host)
- Products requiring updates/maintenance
- Teams without DevOps resources
Revenue potential: $5K-500K/year
Model 3: Sponsorships
How it works:
- GitHub Sponsors, Open Collective, Patreon
- Companies and individuals donate
- Often tied to usage or visibility
Examples:
- Vue.js (Evan You - $500K+/year)
- React Training
- Many npm package maintainers
Best for:
- Popular projects with large user base
- Projects used by companies
- Maintainers with personal brand
Revenue potential: $1K-100K/year
Model 4: Consulting and Support
How it works:
- Software is free
- Charge for implementation help
- Charge for priority support
- Charge for custom features
Examples:
- Redis (Salvatore Sanfilippo)
- Sidekiq (Mike Perham)
- Many WordPress developers
Best for:
- Enterprise users needing support
- Complex implementations
- Custom integrations
Revenue potential: $50K-500K/year
Model 5: Dual License
How it works:
- Open source license (GPL, AGPL) requires sharing code
- Commercial license allows proprietary use
- Companies pay to avoid open source requirements
Examples:
- Qt (desktop framework)
- MySQL (before Oracle acquisition)
- MongoDB (before SSPL change)
Best for:
- Libraries used in commercial products
- Tools with strong copyleft licenses
- Enterprise-focused projects
Revenue potential: $100K-10M+/year
My Recommendation
For most indie developers:
Start with Model 2 (SaaS Hosting) + Model 3 (Sponsorships)
- Make code open source
- Offer hosted version for convenience
- Add GitHub Sponsors for community support
This gives you:
- Recurring revenue from hosting
- Community support and goodwill
- Lower barrier to adoption
Implementation Steps
Step 1: Validate demand
- Are people using your project?
- Are companies using it?
- Are they asking for features?
Step 2: Choose your model
- Open core for clear free/paid features
- Hosting for complex software
- Sponsorships for community projects
Step 3: Set up payment
- Stripe for SaaS
- GitHub Sponsors for donations
- Lemon Squeezy for simplicity
Step 4: Communicate clearly
- README explains monetization
- Pricing page for hosted version
- Sponsorship tiers and benefits
Common Mistakes
- Changing license without community input
- Making free version too limited
- Not communicating value of paid features
- Ignoring community feedback
- Expecting immediate revenue
Final Thoughts
Monetizing open source is possible but not easy. It requires a great product, clear value proposition, and patience.
Start with what your users need, price fairly, and build from there.
Building a SaaS? SaaSLaunch gives you the technical foundation so you can focus on your product, not boilerplate.
