Choosing the Right License for Your Bioinformatics Python Package
When developing a bioinformatics Python package on GitHub, choosing the right license is essential. Your license determines how others can use, modify, and distribute your software. This article will help you pick the best option.
Why Does a License Matter?
A software license clarifies:
- Whether your code can be used commercially.
- If modifications and redistribution are allowed.
- Whether derivative works must remain open-source.
Recommended Licenses for Bioinformatics
1. MIT License (Most Permissive)
- ✅ Allows: Unrestricted use, modification, and distribution.
- ✅ Requires: Attribution to the original author.
- ❌ Does not require: Derivatives to be open-source.
Best for: Maximizing adoption and usage.
📌 Example:
2. GNU General Public License (GPL-3.0) (Most Restrictive)
- ✅ Allows: Modification and redistribution.
- ✅ Requires: All derived works to remain open-source (Copyleft).
- ❌ Not suitable for: Proprietary/commercial extensions.
Best for: Ensuring improvements remain open-source.
📌 Example:
3. Apache License 2.0 (Permissive + Patent Protection)
- ✅ Allows: Free use, modification, and distribution.
- ✅ Includes: Patent protection against legal claims.
- ✅ Requires: Attribution, but allows closed-source derivatives.
Best for: Projects needing permissive licensing with extra legal protection.
📌 Example:
4. BSD 3-Clause License (Permissive, MIT Alternative)
- ✅ Allows: Modification and redistribution.
- ✅ Protects: Against misuse of project names.
- ✅ Allows: Commercial and proprietary use.
Best for: Permissive licensing with name protection.
📌 Example:
Summary Table
| License | Open-Source Required? | Commercial Use? | Modification Allowed? |
|---|---|---|---|
| MIT | ❌ No | ✅ Yes | ✅ Yes |
| GPL-3.0 | ✅ Yes | ✅ Yes | ✅ Yes (must be open-source) |
| Apache 2.0 | ❌ No | ✅ Yes | ✅ Yes |
| BSD 3-Clause | ❌ No | ✅ Yes | ✅ Yes |
Which License Should You Choose?
- If you want maximum adoption → MIT or Apache 2.0.
- If you want derivative work to remain open-source → GPL-3.0.
- If you want minimal legal risk but some name protection → BSD 3-Clause.
