  136. <li><a href="gpl.html">GNU GPL</a> Open Source license.</li>
  137. </ul>
  138. <h2>GoAhead Commercial License</h2>
  139. <p>The GoAhead commercial license is a royalty-free license that provides you with the following benefits:</p>
  140. <ul>
  141. <li>The right to develop and modify the software to embed in your products</li>
  142. <li>The ability to redistribute your products with the software</li>
  143. <li>The ability to keep your source code private</li>
  144. <li>Simple royalty-free, one-time purchase options</li>
  145. <li>Software maintenance for updates, upgrades and security patches</li>
  146. <li>Priority software support services</li>
  147. </ul>
  148. <p>If you require a commercial license or commercial support for GoAhead, please contact us at:
  149. <a href="mailto:licensing@embedthis.com">licensing@embedthis.com</a>.</p>
  150. <h2>Open Source License</h2>
  151. <p>GoAhead my be used with the <a href="gpl.html">GPL Open Source license</a>. This is ideal for evaluating
  152. GoAhead, for internal use, stand-alone use, or for integrating exclusively with other GPL software.
  153. If you intend to distribute your software and link GoAhead with your application, the GPL requires you
  154. to provide public and full access to all source code and documentation on a nondiscriminatory basis.
  155. If you do not wish to provide source code to your application, you must purchase a commercial license.</p>
  156. <h3>Evaluating GoAhead</h3>
  157. <p>If you are evaluating GoAhead internally, and not distributing any products containing GoAhead, then you may
  158. be able to use the GPL license for this evaluation. Once complete, you may purchase a commercial license so
  159. that you can distribute your product. You may evaluate, develop, modify, and embed GoAhead in your
  160. application or product provided it is not distributed. You may copy and modify the source code provided
  161. all copies fall under the GPL license.</p>
  162. <h3>Stand Alone Use</h3>
  163. <p>If you are using GoAhead in a stand-alone manner as free-standing binaries, and are not integrating the
  164. GoAhead source code or libraries with your software to create a derivative work, then the GPL license may
  165. be sufficient. Stand-alone use does not permit linking GoAhead using either static or dynamic linking.</p>
  166. <h3>Use with Other GPL Software</h3>
  167. <p>If you are integrating GoAhead source or libraries into your application and your software is also
  168. fully licensed under the GPL license, you may use GoAhead with the GPL license and embed GoAhead
  169. in your applications or devices. You do not need any other agreement or license &mdash; the GPL is all you
  170. require.</p>
  171. <h3>Embedding with Non-GPL Software</h3>
  172. <p>If GoAhead is embedded into your application, or your application is linked using static or dynamic
  173. linking with libraries containing any GoAhead source code and you do not wish to publish your source code
  174. under the GPL, then you will need the GoAhead Commercial license.</p>
  175. <p>Please contact <a href="mailto:licensing@embedthis.com">licensing@embedthis.com</a> if you have any
  176. questions about licensing GoAhead.</p>
