Intellij IDEA Community Edition - commercial proprietary software developing
<p>Can I use free Intellij IDEA Community Edition for the developing, if I'm working on the proprietary commercial product?</p>

<p><strong>Yes.</strong></p>

<p>Intellij IDEA Community Edition is (almost) entirely licensed under the Apache 2.0 license (<a href="http://www.jetbrains.org/display/IJOS/License+Information" rel="nofollow">http://www.jetbrains.org/display/IJOS/License+Information</a>). </p>

<p>The Apache 2.0 license allows for commercial use (<a href="http://choosealicense.com/licenses/apache-2.0/" rel="nofollow">http://choosealicense.com/licenses/apache-2.0/</a>).</p>

<p>The following is my understanding of the problem:</p>

<p>You are not restricted to what kind of software you develop unless you are developing a product that is derived from Intellij IDEA, for example, if you are developing your own IDE that is derived from IDEA.</p>

<p>That being said, you can even use the commercial version of Intellij IDEA to develop a commercial product that is not an IDE itseft and doesn't use Intellij IDEA's source code.</p>

<p>In addition to the Apache 2.0 license for IDE, there are also now some bundled with plugins that are now proprietary JetBrains license: <a href="https://www.jetbrains.com/legal/community-bundled-plugins/?product=iic&amp;version=2021.1" rel="nofollow noreferrer">https://www.jetbrains.com/legal/community-bundled-plugins/?product=iic&amp;version=2021.1</a>.</p>
<p>There doesn't look to be any restriction on using those plugins for a commercial purpose.</p>
