Top 7 Angular Gantt Chart Libraries in 2026

If you're building an Angular app that needs a serious Gantt chart — for project management, resource scheduling, manufacturing planning, or anything timeline-heavy — you've probably realized that picking the right library is harder than it should be.

Most "top 10" articles you'll find online are either thinly disguised marketing for a single product, or so superficial they don't help you decide anything. So I sat down and did the comparison I wish I had found when I started.

This post evaluates 7 Angular-compatible Gantt chart libraries using the same 8 criteria for each one. No hidden favorites, no skipped sections — every library gets the same treatment.

How I evaluated each library

Every library is scored against the same 8 criteria:

Angular integration — Native, wrapper, or pure JS adapted?
Performance — How does it behave at 10k+ rows/tasks?
Customization — How deep can you go before hitting walls?
Built-in features — Critical path, dependencies, drag & drop, etc.
TypeScript support — Real types, or any everywhere?
Licensing & pricing — Free? Per-developer? OEM?
Documentation & support — Community vs paid?
Best-fit use case — Where does it actually shine?

Let's dig in.

1. ScheduleJS

Website: schedulejs.com

ScheduleJS is the JavaScript/TypeScript port of FlexGanttFX, a JavaFX scheduling library used in industries like aviation, broadcasting, and manufacturing. It's built specifically for real-time scheduling at scale rather than traditional project-management Gantt views.

Criterion

ScheduleJS

Angular integration

Native Angular library, built with TypeScript from the ground up

Performance

Canvas-based rendering, designed for hundreds of thousands of rows with smooth scrolling

Customization

Pixel-level via object-oriented API — every element is overridable

Built-in features

Drag & drop, multiple layouts (Gantt/Chart/Agenda), tree tables, dependencies

TypeScript support

First-class — written in TS

Licensing & pricing

Commercial license, contact sales for quote

Documentation

Developer manual + API docs, paid support included

Best-fit use case

Real-time resource planning, MES/MOM systems, airline ops, broadcasting

Strengths: Where ScheduleJS clearly wins is flexibility and big-data performance. The canvas engine doesn't choke on huge datasets, and the OO API lets you reshape the component for industry-specific UX rather than fighting against opinionated defaults.

Weaknesses: No built-in business logic for things like critical path or auto-scheduling — you implement those yourself. Documentation is good but the community is smaller than DHTMLX/Bryntum. Pricing isn't public, which slows down evaluation.

Pick it if: You're migrating from FlexGanttFX, or building a complex scheduling app where stock components fall short.

2. DHTMLX Gantt

Website: dhtmlx.com/docs/products/dhtmlxGantt

DHTMLX is one of the most popular Gantt libraries in the JS world. It can be integrated into Angular applications via npm, and the library publishes official starter projects on GitHub for Angular, React, Vue, Salesforce, and more.

Criterion

DHTMLX Gantt

Angular integration

Pure JS lib + npm package, integration via container element

Performance

Renders 30,000+ tasks in milliseconds according to vendor benchmarks

Customization

HTML template system + extensive API

Built-in features

Critical path, auto-scheduling, resource management, MS Project export (PRO)

TypeScript support

Improving — historically had a lot of any, but vendor has updated d.ts files

Licensing & pricing

GPL v2 (open source) for Standard Edition; commercial license for PRO; Startup from $569

Documentation

Extensive — 850+ live samples, integration guides for many stacks

Best-fit use case

Project management apps, MS Project replacements

Strengths: Mature, battle-tested, huge sample library. The GPL Standard edition is genuinely usable for OSS projects, which is rare in this space.

Weaknesses: A few user reviews note that the Angular integration "could be better" and TypeScript support has historically had gaps. Default skins look dated compared to Bryntum or Syncfusion.

Pick it if: You want a proven all-rounder with the option to start free and upgrade.

3. Bryntum Gantt

Website: bryntum.com/products/gantt

Bryntum is the polished, premium option. It's described as "the most reliable and feature-complete JavaScript Gantt chart component" with native wrappers for Angular, React, and Vue, supporting 45 locales out of the box and CSS-variable theming.

Criterion

Bryntum Gantt

Angular integration

Official Angular wrapper

Performance

Supports 1,000,000+ records according to vendor, though independent tests show slowdowns past ~2,000 tasks for some operations

Customization

CSS variables for theming, comprehensive API, 5 preconfigured themes with light/dark modes

Built-in features

Critical path, baselines, S-curve progress, conflict resolution, MS Project/Excel export

TypeScript support

Full TypeScript definitions

Licensing & pricing

Commercial only, starts around $940 per developer

Documentation

Excellent — guides, live demos, API docs, paid support

Best-fit use case

Polished project management UIs, enterprise SaaS products

Strengths: The cleanest UI/UX out of the box. Great theming, frequent releases (maintenance every 2 weeks per their own docs), and a very thorough feature set for project management.

Weaknesses: Cost adds up fast for larger teams. A few G2/Capterra reviews mention that integrating into existing UIs and matching design systems took more effort than expected.

Pick it if: Budget allows, and you want the best out-of-the-box visual quality.

4. Syncfusion Angular Gantt

Website: syncfusion.com/angular-components/angular-gantt-chart

Syncfusion's Gantt is part of the larger Essential JS 2 (EJ2) suite — a commercial product offering 140+ Angular UI components, with a free community license available for organizations under $1M USD in annual revenue.

Criterion

Syncfusion Angular Gantt

Angular integration

First-class Angular wrapper, Ivy-compatible, supports Angular 12+ including Angular 21

Performance

Virtual scrolling for handling large datasets without performance degradation

Customization

Theme Studio GUI, multiple themes (Fluent, Tailwind, Bootstrap, Material)

Built-in features

Critical path, task dependencies (FS/SS/FF/SF), auto/manual scheduling, predecessors

TypeScript support

Full Angular + TypeScript

Licensing & pricing

Subscription model; free Community License for individuals and small companies (<$1M revenue, <5 devs/10 employees)

Documentation

Comprehensive — guides, API, demos, AI Coding Assistant

Best-fit use case

Teams already using the Syncfusion UI suite

Strengths: If you need 100+ UI components and a Gantt, Syncfusion is excellent value. Strong accessibility (WAI-ARIA), good docs, active blog.

Weaknesses: Expensive if you only need the Gantt — you're paying for the whole suite. Not the best fit if you're cherry-picking a single component.

Pick it if: Your stack already uses Syncfusion, or you qualify for the community license.

5. Frappe Gantt

Website: github.com/frappe/gantt

The minimalist open-source option. Frappe Gantt is a lightweight, MIT-licensed library focused on simplicity rather than enterprise-scale scheduling. It uses SVG rendering and supports basic task/milestone visualization, simple dependencies, drag-and-drop, and zoom levels (day/week/month/quarter).

Criterion

Frappe Gantt

Angular integration

Framework-agnostic with community wrappers for Angular, React, Vue

Performance

Fine for small/medium datasets, not designed for thousands of tasks

Customization

CSS styling, basic API

Built-in features

Drag & drop, simple dependencies, zoom levels, milestones

TypeScript support

Limited — community types

Licensing & pricing

MIT license, completely free for commercial and non-commercial use

Documentation

Brief but clear — README + GitHub issues

Best-fit use case

Prototypes, internal tools, small projects, MVPs

Strengths: Tiny footprint, clean SVG output, MIT license, ~42k weekly npm downloads, ~5.9k GitHub stars. Fast to integrate.

Weaknesses: Lacks features like resource management and critical path analysis, making it unsuitable for complex resource planning or enterprise project tracking. No official Angular wrapper.

Pick it if: You need something simple, free, and fast to ship.

6. ngx-gantt (Worktile)

Website: github.com/worktile/ngx-gantt

The native-Angular open-source option. Built specifically for Angular and published as @worktile/gantt, with standalone component support recommended.

Criterion

ngx-gantt

Extensive customization through templates and CSS

Built-in features

Multiple view types (day/week/month/quarter/year), drag & drop, custom templates

TypeScript support

Full — written in TypeScript

Licensing & pricing

Free (open source, MIT)

Documentation

Good documentation including a getting-started guide, usage examples, and a live demo

Best-fit use case

Angular projects needing a free, idiomatic Gantt

Strengths: Truly Angular-native (uses standalone components, content projection, ng-templates). Free, actively maintained (~295 stars on GitHub at time of writing).

Weaknesses: Smaller community than DHTMLX/Bryntum. Lacks advanced enterprise features (no critical path, no auto-scheduling). Bus factor concerns — primarily one organization behind it.

Pick it if: You're on Angular, want open source, and don't need enterprise-grade scheduling logic.

7. AnyChart Gantt

Website: anychart.com/products/anygantt

AnyChart's Gantt is part of AnyGantt, itself part of the broader AnyChart data-visualization suite. It's positioned as a viz-first Gantt — strong on charts and visual reporting.

Criterion

AnyChart Gantt

Angular integration

JS library + Angular integration via npm

Performance

Good for typical dashboards; not benchmarked at the same scale as ScheduleJS/Bryntum

Customization

Strong styling APIs, Live Editor

Built-in features

Resource Gantt, Project Gantt, dependencies, milestones

TypeScript support

TypeScript definitions available

Licensing & pricing

Commercial license; free for non-profit/educational

Documentation

Solid — playground, gallery, API

Best-fit use case

Data dashboards combining Gantt with other charts

Strengths: Tight integration with the rest of AnyChart's chart catalog (perfect if you also need pies, maps, stocks, etc.). Pleasant visual defaults.

Weaknesses: Not the deepest Gantt feature set on this list. If you only need a Gantt, you're paying for breadth you won't use.

Pick it if: Your app is a dashboard mixing Gantt with other visualizations.

Which one should you actually pick?

Decision shortcuts:

You need to handle massive real-time data (airline ops, manufacturing, broadcast): ScheduleJS
You want a proven all-rounder with paid support: DHTMLX or Bryntum
You want the best out-of-the-box look & feel: Bryntum
You're already on the Syncfusion suite: Syncfusion Gantt
You're shipping an MVP and need it free: Frappe Gantt or ngx-gantt
Your app is dashboard-heavy with mixed charts: AnyChart

A note on benchmarking yourself

Whatever you pick, build a small POC with your real data before committing. Vendor benchmarks always assume ideal conditions. Things that will trip you up:

Number of dependencies between tasks (often the real perf bottleneck, not row count)
Custom row heights and mixed layouts
Real-time updates (websocket-driven changes vs initial render)
Mobile/touch interactions

A weekend POC can save you a 6-month migration later.

Wrapping up

There's no single "best" Angular Gantt library — the right one depends on your scale, budget, and how custom your scheduling logic is.

If your project leans toward complex, real-time, large-dataset scheduling and you've outgrown what off-the-shelf project-management Gantts can do, take a look at ScheduleJS — that's the niche it was built for. For straightforward project management, DHTMLX and Bryntum remain the safe bets.

Whatever you pick: prototype before you commit.
