Gantt Chart Maker Open App

A serious Gantt tool. Free to the last feature.

Open it in a browser and you get the whole thing: all four dependency types, exports that survive a slide deck, live collaboration, and an assistant that builds the chart while you describe it. No account to start, and no paywall waiting at the end.

A small Gantt chart of a website redesign: Discovery, Design, Build, QA and polish across March to May 2026, joined by dependency arrows, ending on a launch milestone.
Five tasks, the arrows between them, and a launch milestone. This is a real export from the app, drawn by the same renderer that will draw yours.

Twelve reasons it can be your only Gantt tool

Every one is free, and every one links to the place in the app where you can try it.

Completely free

Every feature on this page costs nothing. There is no trial timer, no card field, and nothing sitting behind an upgrade button. You can build a full chart with dependencies and exports before you make an account, and the account is free too: it only adds what genuinely needs a server.

Output you can present

Charts here are meant to be shown, not just kept: clean type, dependency arrows that route around bars instead of through them, and exports that look right dropped into a deck. It stays one fast page rather than an enterprise suite with a chart hidden somewhere inside.

All four dependency types

Most free tools stop at Finish-to-Start. This one also does Start-to-Start, Finish-to-Finish and Start-to-Finish. Drag between two tasks, pick the type, and the arrows redraw as you move things, so the timeline keeps telling the truth about your constraints.

Export almost anywhere

Send a chart to PDF, PNG, JPG or SVG when you need the picture, or to Excel and CSV when you need the data. Choose the resolution and background, frame the export around your tasks, and get a file that matches the screen. SVG stays sharp at any size, and the spreadsheets import straight back in.

Imports the plan you already have

Bring a plan across from Microsoft Project or TaskJuggler, or from the Excel, Google Sheets and CSV exports most other tools produce. Columns map back onto tasks, dates and structure, so switching over takes minutes instead of an afternoon of retyping.

An MCP server for your AI

A built-in MCP server lets an assistant like Claude create charts, add and edit tasks, and link dependencies while you describe what you want. Ask for a three-phase website redesign with QA at the end, and the bars appear. Your timeline becomes something you can say out loud.

Real-time collaboration

Sign in, share a chart by email or by link, and edit it with your team at the same time. Changes land the instant they happen, so there is no refresh, no merge conflict, and no question about who holds the current version. A public link lets people read it without an account.

Live collaborator cursors

While you work together, everyone's cursor moves across your screen with their name and colour attached. You can see who is dragging which task before they say a word, and that small cue is what makes editing together feel calm instead of crowded.

Watch cursors move →

Cloud save on every device

Sign in and charts sync on their own, so you can pick up on a laptop what you started on a phone, and every chart gets a link you can bookmark. Without an account, charts stay in your browser. Cloud save is the opt-in that adds backup and access from anywhere.

Forty-two ready-made templates

You do not have to start from an empty page. Pick a chart for a wedding, a renovation, a product launch, a sprint, a marathon or a dissertation, then reshape it in seconds. It is the quickest way to learn the tool and a quicker way to ship a plan.

Browse templates →

Install it, then work offline

Add Gantt Chart Maker to a desktop or a phone and it opens in its own window, with no browser chrome around it. After the first visit it runs offline, so a chart on your device stays editable on a plane. No app store, no download size, and always the current version.

Open and install →

Eight languages

The whole interface, not only the marketing copy, is translated: buttons, dialogs, dates and tooltips in English, Greek, Spanish, French, German, Italian, Swedish and Finnish. Switch whenever you like, and your charts come along unchanged.

What is free, and what an account adds.

Free, with no account

The whole editor. Tasks, groups, milestones, all four dependency types, templates, imports, every export format, printing, and offline use. Charts live in your browser and nothing is withheld.

Free, once you sign in

The things that genuinely need a server: cloud save across devices, a link for each chart, sharing by email or link, live collaboration, version history, and the MCP connection for AI assistants.

What never happens

No paid tier, no trial that expires, no feature that asks for a card. Charts stay yours, and you can export every one of them to a file and take it elsewhere whenever you want.

Four ways one task can wait for another

A dependency says this cannot happen until that does, and real plans need more than one shape of it. Pick a type to see how it links two tasks.

  • Finish-to-Start. The classic: the second task starts once the first is done.
  • Start-to-Start. Both begin together, which is how parallel work is drawn.
  • Finish-to-Finish. The two wrap up in step with each other.
  • Start-to-Finish. Rare, but exactly right for a handoff or a shift change.

One chart, several people, at the same moment

Invite your team and plan together live. Every change syncs as it happens, and each person's cursor glides across the chart with their name on it, so coordination happens by looking rather than by messaging.

Collaboration and cloud sync are the two features that need a free account, because they need a server to exist at all. Everything else on this page works with no sign-in.

History, laid out as a Gantt chart

Take a long, tangled stretch of history, draw it as overlapping events, and the sequence finally makes sense. Three are plotted with real dates. Open any one and it is yours to edit.

More timelines are on the way. Want a particular one? Open the app and you can build it yourself today.

Build something in two minutes

No account, no install, no card. Start from a blank chart or from a template, and keep whatever you make.
