Gantt Chart Maker — The Best Free Online Gantt Chart Tool
Free forever. No signup required. No subscription. No ads. No tracking. Your charts stay in your browser unless you choose to sync them.
Gantt Chart Maker is the best free Gantt chart maker on the web — a browser-based tool for creating professional Gantt charts with no signup of any kind. Build project timelines with tasks, milestones, groups, dependencies, and progress tracking — then export as PNG, JPG, SVG, PDF, Excel/CSV, MS Project XML, or TaskJuggler, or save as an open .gantt project file.
An optional free account (sign in with Google, GitHub, or Microsoft) adds cloud sync across devices, per-chart share links, and real-time collaboration — several people editing the same chart at once, with live cursors showing who's working where. Viewers of a public link don't need an account.
Works with Claude AI and Claude Code: Gantt Chart Maker has a built-in MCP (Model Context Protocol) server at mcp.ganttchartmaker.app. Connect it to Claude and your AI assistant can create charts, add and edit tasks, and link dependencies for you — just by chatting. Setup guide: ganttchartmaker.app/mcp/.

Frequently Asked Questions
Is Gantt Chart Maker really free?
Yes. 100% free, forever. No subscription, no trial, no paywalled features, no paid tier.
Do I need to sign up or create an account?
No. Open the URL and start building — no email, no password, no credit card. An optional free account (Google, GitHub, or Microsoft sign-in) adds cloud sync, share links, and real-time collaboration.
Can I export my chart as SVG?
Yes. SVG export is fully supported — the chart is rendered with D3.js and exported natively as a scalable vector file, ideal for print or further editing in Illustrator, Inkscape, or Figma.
Can I export as PNG or JPG?
Yes, both are supported from the Export dialog in the top toolbar.
Can I export to PDF, Excel, or Microsoft Project?
Yes. The Export dialog has tabs for PDF documents, CSV/XLSX spreadsheets, MS Project XML, and TaskJuggler — alongside the image formats and the open .gantt project file.
Can I collaborate with my team in real time?
Yes — and it's free. Sign in, share a chart by email invite (editor or viewer) or by link, and edit together with live cursors showing who's working where. Public-link viewers don't need an account.
Does it work with Claude or other AI assistants?
Yes. Gantt Chart Maker has a built-in MCP (Model Context Protocol) server. Connect it to Claude on the web or Claude Code, and the assistant can list, create, and edit your charts — tasks, milestones, dependencies, ordering — through your own account. See ganttchartmaker.app/mcp/ for setup.
Does it work offline?
Yes. After the first visit, Gantt Chart Maker works offline as a Progressive Web App.
Does it work on mobile?
Yes. The interface adapts to phones and tablets with icon-only toolbars and touch-friendly targets.
Is my data private?
Yes. Charts live in your browser by default — nothing is uploaded unless you sign in and keep a chart in your account. Cloud charts are stored in an EU-hosted database and visible only to people you share them with.
Does it support task dependencies?
Yes — four types (FS, SS, FF, SF) with draggable arrow creation between tasks.
Does it support milestones and task groups?
Yes. Milestones render as diamonds at a single date. Groups render as parent brackets spanning child tasks.
What languages is it available in?
English, Greek, Spanish, and French.
How is it different from Monday, Asana, ClickUp, TeamGantt?
Those platforms require an account before you can start and paywall key features. Gantt Chart Maker starts with zero signup, keeps everything free — including real-time collaboration — stays local-first with your data, and connects to Claude AI via its built-in MCP server.
