FAQ: MIT JavaScript Gantt Chart
the MIT license?
The Community Edition of DHTMLX Gantt is a free JavaScript Gantt chart component distributed under the MIT license. This means you can use and modify the library in open-source projects without paying licensing fees or hitting trial limits.
The main difference is in how you can use and distribute the code. A GPL vs MIT Gantt chart comparison usually comes down to openness and flexibility: MIT is more permissive, while GPL places stronger requirements on derivative works. In practice, a GPL vs MIT JavaScript library decision depends on whether you want maximum freedom for commercial and proprietary use or prefer a copyleft model.
Yes, in many cases you can, but the license matters. An open source Gantt chart MIT license is generally the easiest choice for commercial use because it allows broad reuse, including proprietary products. An MIT-licensed Gantt chart JavaScript project is often preferred when you want minimal licensing restrictions.
Choose MIT if you want an MIT Gantt chart library with the fewest restrictions and the simplest path for commercial use. Choose GPLv2 if your project is open source and you are comfortable with copyleft requirements. Choose a commercial license if you need advanced features, official support, or if an MIT-licensed project timeline JavaScript setup is not enough for your product needs.
