Understanding software licenses is important whether you’re a developer, business owner, or just someone who uses apps. Here’s a quick and easy guide to the most common software licenses out there.
🔓 Open Source Licenses
These licenses allow anyone to view, use, and often modify the source code.
1. MIT License
- Simple Meaning: Do whatever you want with the code, just give credit to the original creator.
- Example Use: Small projects, very flexible.
2. Apache License 2.0
- Simple Meaning: Like MIT, but adds legal protection from patent issues.
- Example Use: Used by big companies like Google.
3. GNU GPL (General Public License)
- Simple Meaning: You can use and change the code, but anything you share must also be open source under the same license.
- Example Use: Ensures software stays free forever.
4. GNU LGPL (Lesser GPL)
- Simple Meaning: Like GPL, but allows the code to be used in closed-source software too.
- Example Use: Common for libraries.
5. BSD License
- Simple Meaning: Do what you want, just keep the license and credit.
- Example Use: Used in both academic and commercial projects.
6. Creative Commons (for content)
- Simple Meaning: Not for code, but great for images, docs, or design. Some rights reserved.
- Example Use: Software documentation or media.

These licenses are more restricted and usually don’t allow modification or redistribution.
1. EULA (End User License Agreement)

- Example Use: Microsoft Office, Photoshop.
🧪 Other or Mixed Licenses
1. Dual Licensing
- Simple Meaning: Same code, two license options—usually one free, one commercial.
- Example Use: Gives flexibility to different users.
2. Public Domain
