Pro edition
Add-ons
Standard edition
Resource management
DHTMLX Gantt enables end-users to allocate multiple resources, like personnel and facilities, to projects and tasks. It also helps to adjust the assignments accurately with the help of various load charts and histograms.
Critical path
It is possible to highlight the minimum duration of an entire project and determine the most vital tasks due to the built-in critical path calculation in DHTMLX Gantt. Moreover, the chart allows displaying the slack time and setting the lag and lead times.
Auto scheduling
The DHTMLX JavaScript Gantt chart library includes automatic scheduling functionality. If an end-user changes the duration of a particular task, the auto-scheduling extension updates all due dates automatically, taking into account task dependencies.
Node.js server module
It is an indispensable tool for external integration with complex CRM or ERP systems, real-time collaboration with many people working simultaneously on the same timeline, and clientless integrations with calculations based on calendars and links performed on the fly.
PDF/PNG export module
It is a standalone module that you can install locally to export Gantt charts of any size to PDF and PNG formats without the need to send your data to our server. In addition to PDF and PNG, it provides the ability to convert Gantt projects to iCal and Excel files.
MS Project and Primavera P6 module
You can also deploy an export module for MS Project and Primavera P6 on your server. This module serves to export and import Gantt data to the most popular project management formats securely.
Drag and drop
The DHTMLX JavaScript Gantt chart supports diverse drag-and-drop operations. End-users can move several tasks, create tasks from scratch, and reorder columns in the grid with the help of drag and drop. Developers can control all the behavior via API.
Inline editing
Due to a keyboard navigation mode, end-users are free to manage all tasks right in the grid via inline editing. Keyboard shortcuts allow the creation and update of project tasks and their relations.
Tooltips
You can add tooltips to any DHTMLX Gantt elements like tasks, connectors, milestones, or anything else. Tooltips can contain any information you need. You can fully customize their appearance and behavior to meet your requirements.

What Customers Say

It's stable. It's easy to set up, even if you don’t have too 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.
Dmitry (Dan) Dudin
CEO at GanttPRO
The API is extremely flexible, well documented and easy to understand if you need to look at underlying source code. The support has been responsive and high quality. We would absolutely recommend using DHTMLX and are even considering using some other products that they offer based on our experience so far.
Hive Team
Team productivity platform
For Splitvice, dhtmlxGantt fits with what we need. It's a stand-alone component, without an extra run-time fee. It's flexible and highly customizable. We get good support when we need it, but most of our questions are found right in the knowledge database.
