## What it is
DHTMLX Gantt is an open-source JavaScript Gantt chart library for building project scheduling and timeline interfaces in web applications. It supports task dependencies, drag-and-drop editing, and integrates with plain JavaScript as well as React, Angular, Vue, and Svelte.

## Use cases
- render a gantt chart for project schedules in a web app
- visualize task dependencies and timelines interactively
- build a project management tool with drag-and-drop task editing
- embed a scheduling timeline component in React or Vue
- display milestones and task progress on a timescale
- create a work breakdown structure with hierarchical tasks

## When to choose
- you need a ready-made, feature-rich gantt chart UI without building one from scratch
- your project uses plain JavaScript or a mainstream framework like React, Angular, or Vue
- you want an MIT-licensed component you can fork and modify
- you need interactive editing such as drag-and-drop rescheduling and inline task updates
- you are building a project management or planning tool in the browser

## When to avoid
- you need advanced features like auto-scheduling, critical path, or resource management, which are gated behind the paid PRO edition
- you need a backend scheduling engine rather than a client-side UI component
- your project is not web-based or does not run in a browser
- you want a fully open-source solution with no commercial upsell for core scheduling logic
