Its four core components - Gantt, Scheduler, Grid, and Diagram - are designed for enterprise use cases where out-of-the-box solutions fall short: large datasets, deep customization requirements, and production environments that demand reliable long-term support. With over 20 years of active development, a dedicated engineering team, and thousands of enterprise deployments across the USA, EU, and beyond, DHTMLX stands as one of the most battle-tested JavaScript UI libraries available today. It is used by development teams across industries, including healthcare, manufacturing, logistics, finance, and government. DHTMLX Gantt is built for advanced project and portfolio management in complex environments. It supports hierarchical task structures, multiple dependency types, constraints, and automatic scheduling, enabling accurate planning across large projects. Built-in features such as critical path calculation, baseline tracking, resource management, workload visualization, and progress tracking help teams monitor execution and identify bottlenecks. With support for large datasets, zoomable timelines, split tasks, milestones, and customizable scales, Gantt is well-suited for industries such as construction, manufacturing, and IT project delivery. Its extensible API allows deep customization of task behavior, rendering, and integrations with backend systems. DHTMLX Scheduler provides a flexible and highly interactive solution for calendar and resource scheduling scenarios. It includes multiple view modes such as day, week, month, timeline, and units views, allowing developers to tailor scheduling interfaces to specific use cases. Features like recurring events, drag-and-drop editing, multi-resource assignment, and dynamic loading make it ideal for booking systems, field service management, healthcare scheduling, and workforce planning. Scheduler also supports timezone handling, custom event templates, and real-time updates, ensuring smooth operation in distributed and high-load environments. DHTMLX Grid is a high-performance data grid engineered to handle large volumes of structured data with speed and efficiency. It uses smart rendering and virtualization to ensure fast loading and smooth scrolling, even with hundreds of thousands of rows. The Grid supports advanced features such as sorting, filtering, grouping, inline editing, column reordering, resizing, and freezing, as well as custom cell templates and editors. It also includes data export (Excel, CSV), clipboard operations, and integration with server-side data processing, making it a strong foundation for enterprise dashboards, admin panels, and analytical tools. DHTMLX Diagram enables rich visual modeling and diagramming capabilities within web applications. It supports building flowcharts, organizational charts, decision trees, and BPMN-like process diagrams with a flexible system of shapes, connectors, and layouts. Developers can define custom shapes, control routing logic, and implement interactive editing features such as drag-and-drop, alignment, and grouping. The Diagram component integrates seamlessly with application data, serving as a visual layer for workflows, system architecture, and business process modeling. Together, these components can be combined into fully integrated solutions, e.g., using Gantt for long-term planning, Scheduler for operational resource allocation, Grid for managing large datasets, and Diagram for visualizing workflows, all within a consistent UI and API framework. Beyond these core tools, DHTMLX includes a broader ecosystem of components, including the Suite library with 20+ UI widgets (forms, layouts, charts), Kanban, To Do List, Spreadsheet, Pivot, Vault file upload tool, and Rich Text editor. This allows teams to build complete, end-to-end applications using a single, cohesive technology stack. DHTMLX is built on a stable JavaScript foundation (vanilla JS with optional React, Angular, Vue, and Svelte integrations) and is backend-agnostic, working seamlessly with REST APIs and JSON. Designed for scalability and long-term use, it offers extensive customization, detailed documentation, and responsive technical support, making it a reliable choice for mission-critical enterprise applications.

Tailored for your needs **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Entertainment | Mid-Market (51-1000 emp.) **Reviewed Date:** December 21, 2018 **What do you like best about DHTMLX UI?** Being able to start with a solid foundation of javascript code which still allows me to customize the chart to exactly what I need. The documentation is also amazing with good examples for most cases. **What do you dislike about DHTMLX UI?** There are some scenarios in which documentation becomes hard to come by and examples are few. An example is when figuring out how to get multiple instances of the gantt chart on a page and how to customize each of those gantt charts individually. **Recommendations to others considering DHTMLX UI:** dhtmlxGantt does a lot of things I've found most people want out of a gantt chart. The documentation has for the most part been solid and support has been able to give me an answer whenever I have emailed them about something that I was unable to find in their documentation. Their product also comes with a lot of example code for specific features users would be interested in which have been helpful in seeing how they intended the product to be used. **What problems is DHTMLX UI solving and how is that benefiting you?** Visually representing tasks with dependencies. Being able to start with a good foundation has saved us time in the coding process and has helped keep our team's code more in sync with one another. ### 2.
