What Gantt Chart Maker is
Gantt Chart Maker is a free browser-based tool for creating and editing project schedules. Charts can include tasks, milestones, groups, four dependency types, color coding, priorities, progress tracking, and calendar events. Exports include PNG, JPG, SVG, PDF, CSV/XLSX, MS Project XML, TaskJuggler, and an open .gantt file. Charts stay in the browser by default; when signed out, they are stored locally on the device. A free account adds cloud sync, sharing by link or email invitation, and real-time collaboration. The installable Progressive Web App adapts to phones and tablets and works offline after the first visit. Its MCP server connects to Claude, ChatGPT, Grok, and DeepSeek, with availability depending on the assistant client and plan. MCP exports are limited to Markdown, CSV, Mermaid, or .gantt; PNG, PDF, and SVG exports require the browser app. The free plan is listed as free, with no signup, subscription, or paid tier required. The templates page lists 42 ready-made charts that can be opened without signup or upload.
