# What Is Open Source Risk?

> Open source risk is the legal, competitive, and maintenance exposure from building on or distributing open-source software — including license obligations, copyleft triggers, and community dependency.

**Open source risk** covers the legal, security, and strategic downsides of relying on or distributing open-source software in a commercial product.

### How it works

Risks split into **license compliance** and **operational dependency**. Permissive licenses (MIT, Apache) usually allow proprietary use with attribution. **Copyleft** licenses (GPL, AGPL) may require releasing derivative source if you distribute combined works — problematic for closed SaaS edge cases depending on linking and deployment architecture.

Companies maintain **SBOMs** (software bills of materials), run automated license scans, and adopt policies for approving new dependencies. **Open core** business models open-source a base product while selling enterprise features — community fork risk and cloud competition (AWS hosting your OSS) are strategic concerns, not just legal ones.

Acquirers and enterprise customers increasingly require OSS disclosure in security questionnaires.

### Why it matters

- **Founders:** Implement license review before launch, not before IPO. Relicensing a popular OSS project under a stricter license can force emergency rewrites.
- **Investors:** Diligence flags GPL in mobile apps, unvetted vendor code, and startups whose moat is entirely repackaged OSS without differentiation.

### Common mistake

Assuming "free to use" means "free of obligations." Every OSS license has conditions; ignoring NOTICE files and patent grants creates latent liability.

## FAQ

### What is Open Source Risk in simple terms?

It is the chance that using open-source code creates legal problems — like accidentally obligating you to open your proprietary code — or operational problems when a critical library stops maintained or gets relicensed.

### Why does Open Source Risk matter?

For founders, license violations can block M&A or enterprise sales. For investors, technical diligence scans dependency trees for GPL contamination, unclear attribution, and single-maintainer packages that could break production.
