License FAQ
What license does QueryLeaf use?
QueryLeaf is licensed under the Apache License 2.0, a permissive open source license maintained by the Apache Software Foundation.
Can I use QueryLeaf in a commercial product?
Yes. The Apache 2.0 license allows you to use, modify, and distribute QueryLeaf in any application — commercial, SaaS, internal tools, OEM, whatever you need. No licensing fees, no usage restrictions.
Can I use QueryLeaf in a closed-source application?
Yes. Unlike copyleft licenses, Apache 2.0 does not require you to open-source your own code. You just need to include the license and copyright notice.
What are the requirements of the Apache 2.0 license?
The main requirements are:
- Include the license: Distribute a copy of the Apache 2.0 license with your software
- State changes: If you modify QueryLeaf's source code, note that you made changes
- Preserve notices: Keep copyright, patent, trademark, and attribution notices intact
That's it. No source code disclosure, no copyleft, no network-use provisions.
Are there any restrictions?
The Apache 2.0 license prohibits:
- Using the QueryLeaf name, trademarks, or logos to endorse your product (without permission)
- Holding contributors liable for damages
Does this license cover all QueryLeaf packages?
Yes. All packages — the core library, CLI, Web Server, and PostgreSQL Server — are covered under the same Apache 2.0 license.
Can I modify QueryLeaf and keep my changes private?
Yes. You can modify QueryLeaf for your own use without sharing your changes. If you distribute your modified version, you need to note that changes were made, but you don't have to open-source them.
What about patents?
The Apache 2.0 license includes an explicit patent grant from contributors. If you use the software as licensed, contributors cannot pursue patent claims against you for that use.
How do I get support?
