DHTMLX Gantt and Syncfusion Gantt are both JavaScript Gantt libraries with free licensing paths, visual dependency links, drag-and-drop editing, and TypeScript support. The decision between them turns on where each product draws the free-tier boundary: DHTMLX Gantt locks auto-scheduling, critical path, resource management, baselines, and split tasks behind a paid Pro upgrade, while Syncfusion Gantt includes those features in a product that qualifies for a free Community License for teams under certain revenue thresholds.
The choice usually comes down to these questions:
- Does the organization qualify for the Syncfusion Community License?
- Does the application need auto-scheduling, critical path, resource management, baselines, or split tasks without a paid upgrade?
- Does the team need AI documentation support for Claude Code or another coding agent?
This comparison article compares DHTMLX Gantt and Syncfusion Gantt using these criteria: installation and setup, licensing and cost, scheduling features, export support, framework support, TypeScript support, and AI support.
