Gantify vs GanttProject: a shared online plan, free
GanttProject is a free desktop application that works offline. Gantify is free as well, but it runs in the browser and makes the plan accessible to the whole team, with the logic of MS Project.
In this article
GanttProject has long been one of the most widely used free programs for creating a Gantt chart on your own computer: it works offline on Windows, macOS and Linux and is compatible with Microsoft Project files. Gantify is also free, but it is an online service: the plan is not a file on one person’s disk, but a shared project that the whole team always sees up to date.
The comparison below is based on data from GanttProject’s official website.
Who GanttProject and Gantify are for
GanttProject is designed for people who plan on their own computer, even without a connection[1], and exchange files when needed.
Gantify is designed for people who plan together with others:
- teams that need to work on the same plan without emailing files back and forth;
- project managers who want to receive comments and updates on tasks;
- people who use several devices and want to find the plan always up to date in the browser.

Scheduling
GanttProject lists resource allocation[1]. Gantify provides a scheduling engine modeled on MS Project:
- FS, SS, FF and SF dependencies with lead and lag;
- date constraints and deadlines;
- project and resource calendars with holidays and exceptions;
- an automatic critical path and baselines with the variance of each task;
- multi-level subtasks created with Tab;
- Summary, Gantt, List, Board, Calendar and Workload views, and a version history.
Example: from a local file to a shared plan
A technical manager keeps the plan for an installation in a GanttProject file on their laptop and, every Friday, exports it and sends it to colleagues. With Gantify, the same plan is imported once, colleagues are invited as editors or viewers, and files no longer need to be sent: everyone sees the current version, adds comments on tasks and receives mentions. When the client asks about the status of the work, the read-only public link is all that is needed.
Import, export and migration
GanttProject reads .mpx, .mpp and XML/MSPDI files and exports to XML/MSPDI[1]. Gantify imports .mpp, Microsoft Project XML (MSPDI), .mpx and Primavera .xer files, and exports to Microsoft Project XML, CSV for Excel and print/PDF. The Microsoft Project XML format therefore provides a direct bridge between the two tools, in both directions.
Collaboration
For GanttProject, the official page mentions a paid cloud service[1]. In Gantify, collaboration is included and free: link invitations with roles, tasks that can be assigned to several people, comments with mentions, unique task keys, a change history and a read-only public link.
Pricing
GanttProject desktop is free; the cloud service is pay-as-you-go and its price is not published on the page[1]. Gantify is free, supported by advertising, with collaboration included and unlimited users.
Languages, data and AI assistant
GanttProject works offline and keeps files on the user’s computer[1]. Gantify hosts projects on servers in the European Union, in Germany, and is available in 10 languages. It includes an AI assistant that reads the plan and proposes changes for you to confirm, and an MCP server with API keys for integration with Claude, ChatGPT, Gemini, Cursor and VS Code.

GanttProject remains an excellent free tool for people who work alone on their own computer. Gantify is equally free, but it turns the plan into a shared project, with critical path, comments and a public link, and with a direct path through Microsoft Project XML.
