What gantts.app is

gantts.app is a free Gantt chart maker that runs in a web browser and helps create project timelines. Its interactive schedule lets you drag or resize task bars, set progress, reorder tasks, and schedule work. Four dependency types are supported, with arrows that update when dates change; the app also calculates and highlights the critical path. Tasks can be grouped into phases with roll-up bars, milestones, and automatic numbering. Import task lists from CSV or JSON, or bring in plain-text outlines. Export options include PDF, PNG, Excel, PowerPoint, and JSON, as well as Microsoft Project XML, calendar ICS, Mermaid Gantt text, and an embeddable iframe. Projects are saved in browser local storage, not on the maker’s servers. Shareable links encode project data in the URL fragment. The app can be installed to a home screen and used offline. Its Free plan costs nothing forever, with unlimited tasks, phases, and projects and all features included. No account or credit card is required. Clearing browser data removes saved projects, and the maker cannot access charts to investigate issues or recover lost projects.

Who it suits

gantts.app suits anyone planning work on a timeline who wants to use a browser-based tool without an account, download, or paywall. Its import, export, dependency, and milestone features can support project schedules of varying complexity.

Limits

The Free plan includes unlimited tasks, phases, and projects, with all features. Projects are saved in browser local storage, so clearing browser data removes them; the maker cannot access charts to investigate issues or recover lost projects.

Getting started

1. Open https://gantts.app/ in a web browser.
2. Create a project timeline and add tasks on the interactive schedule.
3. Group tasks into phases or add milestones as needed.
4. Import a task list from CSV or JSON, or a plain-text outline.
5. Export the chart or project data in a supported format.
6. Install the app to a home screen if you want to use it offline.

Verdict

gantts.app includes scheduling, dependency, and export features at no cost, with projects kept in browser storage. Keep a separate copy of important work: clearing browser data removes saved projects, and the maker cannot recover them.
