You’re building a digital product, maybe a WordPress plugin, a downloadable app, or a game. You’ve nailed the features, built your marketing page, and hooked up payments. But then comes the legal and technical side of things: what kind of software license should you use?
It’s not just a legal checkbox. The license you choose defines how your software is distributed, protected, and monetized. It shapes how users can use, share, or resell your product, and how you’ll enforce or automate that access.
In this guide, we’ll break down the most common kinds of software licenses, when to use them, and how WooCommerce businesses can manage licensing easily using tools like WC Key Manager.
What Is a Software License?
A software license is a legal agreement that defines how a user can use a piece of software. Whether you’re selling premium software, offering a free plugin, or distributing open source tools, you’re bound by a license, and so are your users.
Some licenses allow unrestricted use and sharing. Others limit how long the software works, where it can be installed, or how many devices it can run on.
Main Types of Software Licenses
Let’s explore the most widely used software license types, grouped by purpose and restriction.
1. Open Source Licenses
Open source licenses allow users to access, modify, and share the source code. They’re popular among developers and startups looking to build in public or encourage contributions.
Common examples:
- MIT License – Very permissive. Allows reuse with attribution.
- GPL (GNU General Public License) – Requires derivative works to be open source too.
- Apache License 2.0 – Allows commercial use, distribution, and modification.
Best for:
- Developer tools
- WordPress plugins (GPL is required for the repository)
- Collaborative software
2. Freeware
Freeware is software that’s free to use but doesn’t offer access to source code. Users can install and run it, but can’t modify or redistribute it.
Best for:
- Promotional tools
- Entry-level versions of premium software
- Personal productivity tools
3. Freemium / Dual Licensing
Freemium software is offered with basic features for free and advanced features under a paid license. Many WordPress plugins follow this model.
Best for:
- WooCommerce plugins
- SaaS tools
- Digital products with upgrade paths
4. Commercial / Proprietary Licenses
Commercial licenses grant users the right to use the software under strict terms — no source code access, redistribution limits, activation keys, or per-device restrictions.
Variants include:
- Single-site license – One website or user
- Multi-site license – A set number of installations
- Time-limited license – Annual or monthly access
- Lifetime license – One-time purchase with no expiration
Best for:
- Premium plugins and themes
- Game key resellers
- Membership access tools
- Any paid digital product

FAQs
What’s the difference between open source and commercial licenses?
Open source licenses allow users to view and modify code, often with fewer restrictions. Commercial licenses are more restrictive and typically require payment, limiting how the software is used and shared.
Can I offer multiple license types for the same product?
Yes. Many developers offer single-site, multi-site, and lifetime licenses for the same product. WC Key Manager supports assigning different key rules based on product variation or plan.
Do I need a lawyer to create a software license?
For complex use cases, legal help is smart. But many developers start with common templates like the MIT or GPL license. WC Key Manager handles the enforcement side, how keys are activated, restricted, and expired, once you choose your model.
Conclusion: Choose the Right License, Enforce It with Confidence
Choosing the right software license type isn’t just about legal protection — it directly affects how your product grows, how you support it, and how much recurring revenue you earn.
