Your developer just added an open source library to the project and says "it's free, we can use it." Do you trust that? At Meteora Web, we've seen too many projects arrive with incompatible licenses and vulnerable dependencies. A compliance mistake can cost you a lawsuit or a security breach. In this guide, we explain how to use open source in business safely and legally, starting from the real problem: you don't know what's actually in your code.
Why is open source in business a strategic choice that needs management?
Open source isn't "free" in the sense of no cost. It's free as in "liberty," not as in "free beer." You can use, modify, and distribute it, but you must respect the license terms. If you ignore them, you risk copyright infringement lawsuits. But there's more: security. An outdated open source component is an open door for attackers. We see it daily in Italian SMEs: no one tracks dependencies, no one updates them. The result? A compromised website or a data breach that could have been avoided.

The good news? With a simple process, you can turn open source into a competitive advantage. Full control of the code, zero lifetime fees, active community. But it requires discipline.
First step: dependency inventory
Before anything else, you need to know what you're using. Every library, every framework, every tool. Create an inventory with name, version, and license. It sounds tedious, but it's the foundation of everything. Without an inventory, you can't do compliance or security.
Immediate actions: run an audit with tools like FOSSA or Snyk to scan your repository. They tell you licenses and vulnerabilities in minutes.
Which open source licenses can I use commercially without issues?
Not all licenses are the same. The two main families are permissive and copyleft. Permissive (MIT, Apache 2.0, BSD) let you use the code almost as you wish, even in proprietary software. Copyleft (GPL, AGPL) obliges you to release your code under the same license if you distribute the software. For internal use, GPL is fine. But if you distribute or sell the software, you must open your code. AGPL is even stricter: it applies even for network use, like SaaS.

At Meteora Web, we always recommend preferring permissive licenses for critical components. Fewer obligations, fewer risks. But if you use copyleft, document everything and verify the impact on your business model.
How to verify a package license before using it
Check the LICENSE file in the repository. If it's not there, don't use it. Then check choosealicense.com to understand the terms. Finally, use an automatic scanning tool to make sure nothing is missed.
How to manage security of open source dependencies?
Vulnerabilities in dependencies are the leading cause of breaches in web applications. The most famous case? Log4Shell, a flaw in a Java library used everywhere. Companies that hadn't updated it were hit massively. We see it often: servers with expired SSL certificates and outdated plugins. Security isn't an option; it's a process.
The solution is threefold: update regularly, monitor vulnerabilities, and test before going to production. Blind updates aren't enough: you might break something. But not updating is worse.

Automation: your best ally for security
Set up a continuous integration (CI) system that checks dependencies on every commit. Tools like Dependabot on GitHub or Renovate automatically create pull requests when a library has a security update. Your team just reviews and merges. We use this approach for all projects: it reduces risks and saves hours of manual work.
Open source vs proprietary software: which is better for your business?
It depends on the context. If you need standard software (CRM, ERP), proprietary might be faster to implement. But for custom solutions, open source gives you control. Owning your stack beats renting it. Lifetime fees and hostage data aren't the best choice. With open source, the code is yours, the data is yours. And if the vendor disappears, you don't lose everything.
But beware: open source requires internal skills. If you don't have a technical team, it might be more expensive. At Meteora Web, we've seen companies save thousands by switching to open source, but also companies that spent more on consulting. The choice depends on your team and business model.

When open source really saves you money
If you need to build a proprietary platform, open source eliminates licensing costs. Take Laravel, for example: free, with a huge community. We've built multi-tenant platforms for agencies with Laravel, saving tens of thousands of euros compared to SaaS solutions. And the code is ours, not hostage.
How to implement an open source policy in your company?
You don't need a 50-page document. Just a clear policy with three points: which licenses are allowed, how new dependencies are approved, and who is responsible for security. Define a process: every new library must go through review. If it doesn't meet criteria, it's not used.
Responsibility must be clear. In a small company, it can be the senior developer. In a larger one, a committee. But someone must answer if a component is vulnerable.

Checklist for your open source policy
1. List of approved licenses (MIT, Apache 2.0, BSD).
2. Obligation to register every dependency in an inventory.
3. Automatic vulnerability scanning at every build.
4. Monthly dependency updates.
5. Team training on risks and best practices.
What to do now
Don't wait for a problem to wake you up. Here are concrete actions to take now:
1. Scan your code with Snyk or FOSSA to find licenses and vulnerabilities.
2. Update critical dependencies within a week, especially those with high CVSS scores.
3. Write a minimal policy of one page and share it with the team.
4. Automate checks with Dependabot or Renovate.
5. If you lack internal skills, contact us. At Meteora Web, we help you secure your stack.
Open source is an extraordinary resource, but it must be managed. Do it well, and it will give you freedom and savings. Do it poorly, and it will cost you dearly. The choice is yours.
