DHTMLX is a collection of JavaScript UI components for building complex, data-intensive web applications. 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. Key Features - Advanced Gantt chart with dependencies, critical path, auto-scheduling, and resource management. - Interactive Scheduler with multiple calendar views, recurring events, and drag-and-drop editing. - High-performance Grid with virtualization, large dataset handling, and advanced data operations. - Diagram component for workflows, org charts, and BPMN-like visual modeling. - Scalable architecture optimized for complex timelines and high data volumes. - Extensive customization via API, templates, and configuration options. - Seamless integration with modern frameworks and REST/JSON backends. - Extended ecosystem with UI widgets, Kanban, Spreadsheet, Pivot, and more. - Built-in export, data processing, and real-time interaction capabilities. - Comprehensive documentation and responsive enterprise-level support. Key Use Cases DHTMLX is the right choice for development teams building: - Project portfolio management and PMO tools with multi-project Gantt views and resource leveling. - Enterprise resource planning (ERP) modules for scheduling production, logistics, and workforce. - Healthcare scheduling platforms for patient appointments, OR management, and staff rostering. - Construction and engineering project tracking with baseline, critical path, and progress analytics. - SaaS platforms for team collaboration, sprint planning, and delivery tracking. - Back-office data management applications requiring high-density, editable data grids. - Business process management (BPM) tools with visual workflow editors. - IT operations dashboards with network diagrams, infrastructure maps, and live event grids. - HR platforms for org chart visualization and shift planning. - Custom CRM and ERP interfaces requiring complex, interactive UI components.

What problems is DHTMLX UI solving and how is that benefiting you?
It allowed me to build a beautiful website using components like a scheduler. The spreadsheet library is one of the best I frequently use on websites. It will enable me to work with Excel files on my PHP websites easily Review collected by and hosted on G2.com.

"It is a powerful and well-documented tool"
4/5
What do you like best about DHTMLX UI?
The time saving when building a calendar from scratch and the ease to modify events, along with the large number of extensions that can be used. In addition, it is very customizable, since it has several themes to choose from depending on your needs. In our concrete case, we have opted for Material Design. Last, but not least, there is a great coherence between all the extensions and the main module in such a way that just by indicating that you want to use an extension, the main module offers you its new options. The tool also has a forum with great activity of both users and moderators answering. Review collected by and hosted on G2.com.
What do you dislike about DHTMLX UI?
When you need a full functionality or extension that the Scheduler does not provide by default, you have to do reverse engineering to understand and develop it by yourself. Although it has a good documentation and a lot of examples that help you in that task. Review collected by and hosted on G2.com.
Recommendations to others considering DHTMLX UI:
We believe that for our specific case, it has been a profitable investment with a considerable time saving and obtaining a high level of versatility. Review collected by and hosted on G2.com.
What problems is DHTMLX UI solving and how is that benefiting you?
Integrate a calendar into a SaSS tool developed by our organization, https://www.laycos.net. The benefit has been the reduction of development time and related costs. In addition, given the large number of extensions that the tool has, we have been able to increase the characteristics of our own product in aspects that we had not yet taken into account.
