Interactive JavaScript/HTML5 Gantt Chart
for Your Solutions
DHTMLX Gantt is a full-featured Gantt chart for cross-browser and cross-platform applications.
The most complete library to cover all the needs of a project management app.
Key Features of DHTMLX JS Gantt Library
Resource allocation
DHTMLX Gantt provides rich resource management functionality, which enables users to benefit from efficient resource planning techniques. For example, a resource load chart gives insight into the current workload and helps to allocate resources optimally.
Grouping tasks by resources
It is possible to assign as many resources per task as you need. In order to conveniently navigate a project you can group tasks by the assigned resources. Instead of a common Gantt chart you can have a resource view, which allows monitoring task allocation.
Export and import from MS Project
DHTMLX Gantt can be a perfect alternative to MS Project in your application. Our JavaScript Gantt component enables users to import Gantt charts from MS Project as well as export them back as MPP files. Besides, DHTMLX Gantt supports Primavera, Excel, iCal, and PDF/PNG formats.

of tasks. You can load any number of tasks to the JavaScript Gantt component and it

What Customers Say
Best choice for product development. Absolutely
It's stable. It's easy to setup, even if you don't have to much development experience. It's highly customizable. It's full of features out of the box (and if something missing, you can write your own addon to cover missing functionality). It's beautiful out of the box, which is not always the case for similar components. Workload functionality is included, which is not the case for such components.
A complete and easy to use companion for planning and resource management applications development
We have used the DHTMLX components, expecially the scheduler and the GANTT, to realize some complex resource management use cases that would require a lot of effort to realize from scratch. Using these components has significantly reduced the release time providing a good, bug free experience for the end users.
Versatile product and excellent support
We used dhtml for developing the Gantt charts in our project management tool. The product was easy to implement and is evolving continuously. So we are able to always have the best features in our cloud HR and ERP apps.
Truly Exceptional Products!
We searched high and low for a suite of components to make our lives much easier in developing our products, We initially had a need for a Gantt Chart and this one really stood out from the rest. I can tell you that after implementing it on 2 large products we are very impressed with the quality of this component as well as their other products.
Outstanding component
After reviewing many options for a Gantt component, we selected the one from DHTMLX. It is beautifully designed (appearance/UI) which was a key consideration for us, but really it's the full scope of features and capabilities that make it stand out. It has the flexibility for us to make it work exactly the way we need, and it has been a very simple process to integrate it and get it up and running.
