Why Open Source Licenses Matter<\/h2>\n<div class=\"card\">\n <p><strong>Protects both authors and users<\/strong> \u2014 The license clarifies copyright ownership while providing legal protection for users, preventing infringement claims when using open source code.<\/p>\n<\/div>\n<div class=\"card\">\n <p><strong>Defines usage boundaries<\/strong> \u2014 Can the code be used commercially? Must modified code be open-sourced? These critical questions need a license to answer.<\/p>\n<\/div>\n<div class=\"card\">\n <p><strong>Enables community collaboration<\/strong> \u2014 A unified license lowers the legal barriers to collaboration, allowing developers worldwide to contribute under the same rules.<\/p>\n<\/div>\n<div class=\"card\">\n <p><strong>Prevents legal disputes<\/strong> \u2014 Clear licensing terms reduce disputes over code usage, helping the open source community thrive.<\/p>\n<\/div>\n\n\n<h2 id=\"en-categories\">3.

FAQ<\/h2>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: Are open source licenses legally binding?<\/div>\n <div class=\"faq-a\">Yes. Open source licenses are legally enforceable and have been recognized by courts in practice. Violating an open source license may constitute copyright infringement.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: How far does GPL’s “copyleft” reach?<\/div>\n <div class=\"faq-a\">GPL’s copyleft only applies to “distribution.” If GPL code is used internally only, no open-sourcing is required. However, if modified code is distributed externally, it must be open-sourced under GPL. GPLv3 also adds anti-circumvention and anti-Tivoization provisions.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: Can I use MIT\/Apache code in commercial software?<\/div>\n <div class=\"faq-a\">Yes. Both MIT and Apache 2.0 explicitly allow commercial use, including redistributing modified code as closed-source commercial software, as long as the original copyright notice is retained.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: Can a project use multiple licenses?<\/div>\n <div class=\"faq-a\">Yes. This is called “dual licensing” \u2014 allowing users to choose the license that best fits their needs. For example, MySQL offers both GPL and commercial licenses.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: Are open source licenses compatible with each other?<\/div>\n <div class=\"faq-a\">Not fully. For example, GPL code cannot be mixed with MIT code and released under MIT (GPL “overrides” MIT). However, MIT code can be incorporated into a GPL project. License compatibility is a complex topic that requires case-by-case analysis.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: How do I choose a license for my project?<\/div>\n <div class=\"faq-a\">Use the <a href=\"https:\/\/choosealicense.com\/\" target=\"_blank\" rel=\"noopener\">choosealicense.com<\/a> tool \u2014 it guides you through questions to find the best license.

What is an Open Source License<\/h2>\n<p>An open source license is a <strong>legally binding statement<\/strong> by which a software author grants others the permission to use, copy, modify, and distribute the software, while retaining some rights or imposing specific conditions.<\/p>\n<p>Without a license, publicly available source code is protected by <strong>copyright law by default<\/strong> \u2014 meaning no one has the right to use, modify, or distribute it, even if the code is publicly visible. Therefore, an open source license is the <strong>foundation of legal operation<\/strong> for any open source project.<\/p>\n<div class=\"info-box\">\n <strong>In a nutshell:<\/strong> An open source license is a “user manual” from the author that tells others what they can and must do with the code.\n<\/div>\n\n\n<h2 id=\"en-why\">2. Why Open Source Licenses Matter<\/h2>\n<div class=\"card\">\n <p><strong>Protects both authors and users<\/strong> \u2014 The license clarifies copyright ownership while providing legal protection for users, preventing infringement claims when using open source code.<\/p>\n<\/div>\n<div class=\"card\">\n <p><strong>Defines usage boundaries<\/strong> \u2014 Can the code be used commercially? Must modified code be open-sourced? These critical questions need a license to answer.<\/p>\n<\/div>\n<div class=\"card\">\n <p><strong>Enables community collaboration<\/strong> \u2014 A unified license lowers the legal barriers to collaboration, allowing developers worldwide to contribute under the same rules.<\/p>\n<\/div>\n<div class=\"card\">\n <p><strong>Prevents legal disputes<\/strong> \u2014 Clear licensing terms reduce disputes over code usage, helping the open source community thrive.<\/p>\n<\/div>\n\n\n<h2 id=\"en-categories\">3. Two Categories: Permissive vs Copyleft<\/h2>\n<p>Open source licenses can be broadly divided into two categories based on their <strong>copyleft strength<\/strong>:<\/p>\n\n<div class=\"card\">\n <h3><span class=\"tag tag-green\">Permissive<\/span> Permissive License<\/h3>\n <p>Users are free to use, modify, and redistribute the code, even in <strong>proprietary, closed-source<\/strong> commercial software, as long as the original copyright notice is retained.<\/p>\n <p style=\"margin-top:.5rem;\"><strong>Representative:<\/strong> <span class=\"tag tag-blue\">MIT<\/span> <span class=\"tag tag-blue\">Apache 2.0<\/span> <span class=\"tag tag-blue\">BSD<\/span><\/p>\n<\/div>\n\n<div class=\"card\">\n <h3><span class=\"tag tag-red\">Copyleft<\/span> Copyleft License<\/h3>\n <p>Requires that modified or derivative works be distributed under the <strong>same license<\/strong> \u2014 meaning modified code must also be open source (the “viral” effect).

FAQ<\/h2>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: Are open source licenses legally binding?<\/div>\n <div class=\"faq-a\">Yes. Open source licenses are legally enforceable and have been recognized by courts in practice. Violating an open source license may constitute copyright infringement.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: How far does GPL’s “copyleft” reach?<\/div>\n <div class=\"faq-a\">GPL’s copyleft only applies to “distribution.” If GPL code is used internally only, no open-sourcing is required. However, if modified code is distributed externally, it must be open-sourced under GPL. GPLv3 also adds anti-circumvention and anti-Tivoization provisions.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: Can I use MIT\/Apache code in commercial software?<\/div>\n <div class=\"faq-a\">Yes. Both MIT and Apache 2.0 explicitly allow commercial use, including redistributing modified code as closed-source commercial software, as long as the original copyright notice is retained.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: Can a project use multiple licenses?<\/div>\n <div class=\"faq-a\">Yes. This is called “dual licensing” \u2014 allowing users to choose the license that best fits their needs. For example, MySQL offers both GPL and commercial licenses.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: Are open source licenses compatible with each other?<\/div>\n <div class=\"faq-a\">Not fully. For example, GPL code cannot be mixed with MIT code and released under MIT (GPL “overrides” MIT). However, MIT code can be incorporated into a GPL project. License compatibility is a complex topic that requires case-by-case analysis.<\/div>\n<\/div>\n<div class=\"faq-item\">\n <div class=\"faq-q\">Q: How do I choose a license for my project?<\/div>\n <div class=\"faq-a\">Use the <a href=\"https:\/\/choosealicense.com\/\" target=\"_blank\" rel=\"noopener\">choosealicense.com<\/a> tool \u2014 it guides you through questions to find the best license.
