gantt.guru: Collaborative Gantt Charts Without Accounts
A lightweight Gantt chart tool with shareable edit and read-only links — no sign-up required.
Most Gantt chart tools either demand an account before you can do anything or are buried inside full project management platforms. I wanted something I could open, sketch a project plan in, and share with someone — without either of us having to register.
Each project on gantt.guru gets two UUID-based URLs: one for editing, one for read-only viewing. You share whichever link fits. Tasks support subtasks, dependencies (FS/SS/FF/SF), and can be moved or resized directly on the chart. The timeline is zoomable, and finished plans can be exported as PNG, SVG, or vector PDF. Each individual project has its own MCP server you can connect to with a GenAI tool of your choice.
The backend is a FastAPI service with async SQLAlchemy and SQLite. The React frontend uses a Zustand store to manage the chart state and a custom hook for the date-to-pixel math that drives the timeline rendering.
