Ext

Commercial License

This is the appropriate option if you are creating proprietary applications and you are not prepared to distribute and share the source code of your application under the GPL.

• Based on the "Quid Pro Quo" principle, if you wish to derive a commercial advantage by not releasing your application under an open source license, you must purchase an appropriate number of commercial licenses from Ext. By purchasing commercial licenses, you are no longer obligated to publish your source code.

Commercial licenses:

• Are on a per developer basis. Each person who directly or indirectly creates an application or user interface containing Ext components is considered a developer.
• Are perpetual and include upgrades to all minor revisions. For example: a 2.0 license includes all 2.x releases including 2.0, 2.0.2, 2.1, 2.2.1, etc.
• Are royalty-free.
• Remove any obligations to release any source code under GPL.

OEM / Reseller License

This is the appropriate option if you are creating a product that is a software development library, toolkit or framework. There are many benefits to partnering with us:

• With an OEM license, your customers (developers) would not be required to meet the terms of the GPL license and can use Ext functionality under your license terms
• You could offer the only official Ext-based product in your market
• Many opportunities for co-branding and co-marketing
• Get authorized support directly from the Ext team
