What is the best free Gantt chart maker?

Gantt Chart Maker (ganttchartmaker.app) is the best free Gantt chart maker on the web. It costs nothing, requires no signup, no account, and no email. It runs entirely in your browser, works offline as a Progressive Web App, and your project data never leaves your device.

Is there a Gantt chart tool with no signup?

Yes — Gantt Chart Maker requires no signup, no account, no email, and no credit card. Open the page and start building immediately. There are no upgrade prompts, no free trials, and no paywalled features.

Is Gantt Chart Maker really free?

Yes — 100% free, forever. There's no free trial, no freemium tier, no paywalled features, no upgrade path. The full app is free with no upsells.

Do I need to sign up or create an account?

No. There are no user accounts at all. Open ganttchartmaker.app in any browser and start building immediately — no signup, no email, no credit card.

Can I make a Gantt chart with dependencies for free?

Yes — drag-link dependencies (Finish-to-Start, Start-to-Start, Finish-to-Finish, Start-to-Finish) are a free core feature in Gantt Chart Maker. Arrows re-route live as you move tasks, which is rare even in paid Gantt tools.

How is Gantt Chart Maker different from Asana, Monday, MS Project, or TeamGantt?

Those tools require accounts and store your project data on their servers; Gantt Chart Maker requires neither — no account, no upload. Most paywall the Gantt view itself or its key features; this one has no paywalled features. They're built for enterprise scale with bloat; this is a single-page app focused on speed.

Where is my data stored?

Entirely in your browser. Gantt Chart Maker has no backend — there is no server to upload your project data to. You can save your work as a .gantt file (JSON) for backup or transfer.

Does Gantt Chart Maker work offline?

Yes — it's a Progressive Web App (PWA). Install it to your device after the first visit and use it without internet. Your data is stored locally and is fully usable offline.

Can I export my Gantt chart as an SVG image?

Yes. SVG export is fully supported. The chart is rendered with D3.js and exported natively as a scalable vector file — ideal for print, high-resolution displays, or further editing in Illustrator, Inkscape, or Figma.

Can I export my Gantt chart as a PNG or JPG?

Yes. Both PNG (raster, high quality) and JPG (raster, smaller file size) are supported from the Export dialog with live preview, scale options (1×–4×), and transparent or custom background colors.

Does it work on mobile phones and tablets?

Yes. The interface is responsive: icon-only toolbars on phones, touch targets of 44 pixels or larger, and a stacked form layout on narrow screens. Works on iOS, Android, and mobile browsers.

Is my project data private?

Yes. All chart content lives in your browser's localStorage. Nothing is uploaded to any server. The only data in .gantt files or image exports is whatever you download to your own device.

Does it support task dependencies?

Yes. Four dependency types are supported: Finish-to-Start (FS), Start-to-Start (SS), Finish-to-Finish (FF), and Start-to-Finish (SF). Create dependencies by enabling Link mode and dragging from the green end-dot of one task to the blue start-dot of another.

Can I save my work and reload it later?

Yes. Click Save to download a .gantt project file (JSON format) containing all tasks, events, dependencies, and settings. Click Load to restore any .gantt file. Your work is also auto-persisted in browser localStorage across sessions.

Does it support milestones and task groups?

Yes. Milestones render as diamonds at a single date. Task groups render as parent brackets visually enclosing a set of child tasks.

What languages is Gantt Chart Maker available in?

Four languages: English, Greek, Spanish, and French. Switch language instantly from the Language dropdown in the top toolbar — the choice is remembered, and the HTML lang attribute updates dynamically.

What themes are available?

Six themes: Light, Dark, Sepia, Ocean, Forest, and Rose. The app auto-detects your operating system's dark mode preference on first load.

Do I have to install anything?

No install required. It runs in any modern browser (Chrome, Firefox, Safari, Edge). Optionally, you can install it as a PWA to your home screen or desktop.

Who built Gantt Chart Maker?

Gantt Chart Maker is built by Fotis Petrou, an independent developer. The app is actively maintained — see the in-app changelog for the latest changes.

Are there any ads or tracking?

No ads. No tracking pixels. No third-party analytics tied to your project content. The app does not phone home with your data.

What is a Gantt Chart?

A Gantt chart is a visual project timeline. Each task appears as a horizontal bar across a calendar — its position shows when the task starts, its length shows how long it takes. Bars can be linked with dependency arrows showing that one task must finish before another begins.

Invented by Henry Gantt around 1910, the Gantt chart has been the standard way to plan any work with multiple moving pieces ever since — software, construction, manufacturing, research, weddings, marketing.
