Licensing
This page outlines the requirements of the GoAhead open source license and the options for the commercial license. Please note, this text only provides a guideline. You must consult the actual licenses for details of the governing terms.
GoAhead is licensed under the GPLv2 Open Source license. This open source license should meet your needs if you work for a non-profit or educational institution. The open source license can also work well for evaluation within your company or for pure open source projects.
For commercial applications, we recommend a Commercial License. If you require a commercial license or commercial support for GoAhead, please see Commercial License below or contact Embedthis Software.
Embedthis no longer offers the old GoAhead logo branded open source license. The GPLv2 is the only open source license available.
If you have any further questions, please read the licensing FAQ or contact us at

Open Source License
The GPLv2 Open Source license is ideal for integrating with other open source software, internal use, evaluation, and some cases of stand-alone use.
Stand Alone Use
If you are using GoAhead in a stand-alone manner as a free-standing binary, and are not integrating the GoAhead source code or libraries with your software to create a derivative work, then the GoAhead GPLv2 open source license should be sufficient.
Integrating with Other Open Source Software
If you are integrating GoAhead source code or libraries into your application and your software is 100% open source and is licensed under an Open Source License that is GPLv2 compatible, you may use GoAhead with the open source license and embed GoAhead in your applications or devices.
Integrating with Non-Open Source Software
If GoAhead is integrated into your application or your application is linked using static or dynamic linking with libraries containing any GoAhead source code, and you do not wish to publish your source code to satisfy the GPLv2 license, and you wish to redistribute your application, then you will need a commercial license.
GoAhead Download Package
With the GoAhead download, you will receive binaries, source code, samples and documentation and you need not pay any license fees. However, you must abide by all the provisions of the GoAhead Open Source license. There are four main requirements in order to use the GoAhead WebServer in your product with the GoAhead Open Source license:
- You must notify Embedthis prior to any shipment of product containing GoAhead
- You must prominently display the Embedthis GoAhead Logo on the initial page of your embedded Web application or device
- You grant Embedthis permission to identify your company as a user of GoAhead in conjunction with its own marketing efforts, including placing your company logo on the Embedthis web sites.
- You agree to license back to Embedthis all modifications you make to GoAhead under the Embedthis Contributors License.
Please read the GPLv2 Open Source License for full details.
Commercial License
You will need a commercial license if your application is linked with GoAhead, statically or dynamically, and your application source code it is not provided to your customers under an approved open source license, and you wish to redistribute your application. A commercial license includes the added benefits of support services and priority notifications.
In summary, there are several good reasons to purchase a commercial license:
- You require the ability to redistribute your product without displaying the GoAhead branding.
- You do not want to license back your extensions to Embedthis.
- You need a warranty on the GoAhead software (see license for details).
- You do not want to run the risk of your organization's software falling under the governing terms of any open source license.
- You need support services.
- You want priority notification of updates, upgrades, security issues and emergency patches.
