Import a CSV or create manually. Set dependencies, track progress, define milestones, and assign tasks — export a professional Gantt ready for presentations.
Ideal for projects in
without complexity
A straightforward tool that transforms simple data into complete and professional schedules.
Task Progress
Set the completion percentage for each task. The bar is filled visually from left to right, proportional to the progress.
Milestones
Record important dates like deliveries and approvals. Milestones appear as diamonds on the chart, distinct from task bars.
Task Dependencies
Indicate that a task only starts after another finishes. Arrows visually connect the bars to show the execution order.
Assignees
Assign a responsible person to each task. Initials appear as a colorful avatar next to the bar — it's clear who handles what.
CSV Import
Drag or select your file. Supports UTF-8 BOM, formats like DD/MM/YYYY or YYYY-MM-DD, and all new optional columns.
Manual Creation and Editing
Add, edit, and remove tasks directly on the configuration screen, without needing a file. Name, dates, and group editable on the fly.
Free Groups and Colors
Create phases with custom names and colors. Assign each task to the desired group. The legend is generated automatically.
Configurable Text on Bars
Choose what to display: duration, start date, end date, full range, or nothing. Dates can also appear in separate columns.
"Today" Marker
Red line indicating the current date. Appears on the months header, on each row of the chart, and in the legend.
Print and PDF
CSS optimized for A4 landscape with preserved colors. Each task is never cut between pages.
Multi-year and multi-month
The timeline automatically adapts to the project's range. No limit on duration or number of tasks.
Save and Resume
Save the project as .gantt.json and reopen it whenever you want — without losing groups, dependencies, progress, or assignees.
complete result
CSV is a spreadsheet saved in plain text. Each row represents a task; each column, an information — separated by commas.
If you use Excel or Google Sheets, you already have everything: build your table and save it as CSV. Besides mandatory columns, you can include optional columns for dependencies, progress, milestones, and assignees.

What is a Gantt Chart?
The Gantt Chart is one of the most classic and efficient tools for visual project management. It lets you view the entire schedule of activities, showing exactly when each task begins and ends, while highlighting important milestones and dependencies between project phases.
Whether you're a construction project manager, a software developer, or a marketing coordinator, using an online schedule maker like Ganttico helps align your team. By mapping assignees and progress percentages for each step, the visual tool ensures delays are spotted quickly before they become critical bottlenecks for final delivery.
