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.

"Lets a small team ship a serious product"
5/5
What do you like best about DHTMLX UI?
- Feature-completeness from day one — drag-and-drop, recurring events, multiple views, custom event rendering. All the things we'd otherwise have spent months building ourselves.
- Genuine customisability. We've been able to skin it, extend event templates, and integrate it tightly with our PHP/JS stack without fighting the framework.
- Performance with real-world data volumes. Consultants have busy diaries and the calendar stays responsive.
- Well-organised documentation and a responsive support team when we have hit edge cases. Review collected by and hosted on G2.com.
What do you dislike about DHTMLX UI?
Honestly, my gripes are fairly minor and mostly the flip side of working with a mature, comprehensive suite. Mobile and touch UX, particularly on the Scheduler, is at its best on desktop. On smaller screens it does the job, but feels more functional than delightful. Review collected by and hosted on G2.com.
What problems is DHTMLX UI solving and how is that benefiting you?
At its core, DHTMLX solves the build-vs-buy problem on UI components that are deceptively complex. We're a small team building a vertical SaaS for medical consultants in Ireland — every week we'd spend reinventing a scheduler or a data grid is a week we're not building the clinical workflow that actually differentiates our product.

"Seamless Integration and Outstanding Support with DHTMLX Spreadsheet"
4.5/5
What do you like best about DHTMLX UI?
For our use case, we we're looking specifically at the Spreadsheet widget. But we can see how we could apply many of the other DHTMLX widgets on our software.
During the trial phrase, when we did a feasibility study on the use of the DHTMLX Spreadsheet, the team over there responded to all our queries. Both technical and from a sales perspective they were very helpful.
The tool itself is well written and well documented as well. We were particularly impressed with the completeness of the formulas that the Spreadsheet includes. It was easy to setup, in part due to the documentation provided.
And we integrated the widget into our product suite with little effort. Review collected by and hosted on G2.com.
What do you dislike about DHTMLX UI?
To be honest no much, they've been helpful throughout the whole process. Review collected by and hosted on G2.com.
What problems is DHTMLX UI solving and how is that benefiting you?
Time and reliability are probably the biggest factors. The guys are DHTMLX have nailed the design of the product and the cost benefit calculation was pretty simple.
We can buy this off the shelf solution and shortcut a whole bunch of time in our internal development process. Review collected by and hosted on G2.com.

"Great experience using DHTMLX Gantt – simple and powerful!"
5/5
What do you like best about DHTMLX UI?
We are very satisfied with the product. It is incredibly developer-friendly and the documentation is clear and well-structured.

The flexibility and customization options are a big plus. Review collected by and hosted on G2.com.
What do you dislike about DHTMLX UI?
So far, we haven't experienced major issues. However, having more examples for complex use cases (like multi-project views or custom critical path rendering) would be helpful to speed up development even more. Review collected by and hosted on G2.com.
What problems is DHTMLX UI solving and how is that benefiting you?
We needed a powerful and flexible Gantt component to integrate into our operations management system. DHTMLX Gantt has helped us save significant development time by providing an out-of-the-box solution that is highly customizable and easy to implement. It allows our users to visualize and manage planning and execution timelines efficiently, which improves internal coordination and project control. The component’s reliability and performance are essential for our SaaS platform. Review collected by and hosted on G2.com.

Very flexible, good UX thought and capabilities, we could find alternative solutions using DHTMLX components for flexible implementation in our products.

"Fabulous fully featured Gantt chart component !!"
5/5
What do you like best about DHTMLX UI?
The DHTMLX Gantt component has all the features to be competitive with Microsoft Project! When we searched for a component to include in our SAAS product we concluded that this Gantt chart was the very best component available. It has the most features, the most flexible with best set of APIs so we could configure it for our specific requirements.
The documentation is excellent! We have never contacted support to explain any of the APIs or functions. We have contacted support a few times when we have specific behaviors we want beyond the API’s and within hours we have received snippets and instructions on how to accomplish our goals every time. There was nothing that couldn’t be done.
We were abble to integrate this component into our system in less than 1 day. Review collected by and hosted on G2.com.
What do you dislike about DHTMLX UI?
This is a component, so you have to build code around it. We would like to be able to assign resources at the project level as well as the task level....but we understand this is in the pipeline. Review collected by and hosted on G2.com.
What problems is DHTMLX UI solving and how is that benefiting you?
We are using the Gantt component to manage construction planning. There are several unique problems with construction planning that we were able to solve using this component. Review collected by and hosted on G2.com.

"Kanban and Gantt, great stuff!"
4.5/5
What do you like best about DHTMLX UI?
On Kanban:
I have tested the trial version of the Kanban in our Angular app and I find it easy to implement and adapt to project needs. For the sake of fast implementation, I asked the support team a question about how should we customize the Kanban to fit our project needs and got back a detailed and quick response from their development team with explicit example and guidance.
On GANTT:
After testing several gantt options, I chose Dhtmlx Gantt because it fitted my needs perfectly. It's very versatile and easy to use. The documentation is well written and explicit. From the developer's perpective, the gantt is easily integrated and offers a lot of configuration options. After testing the the free version, I stepped to the pro version and the app users we're delighted about the posibility to resize the gantt's column. All in all I recommend this product especially due to its versatility. Review collected by and hosted on G2.com.
What do you dislike about DHTMLX UI?
Probably pricing can be more competitive for startups Review collected by and hosted on G2.com.
What problems is DHTMLX UI solving and how is that benefiting you?
