The exact-match query free gantt chart software describes a crowded category, and the word "free" carries at least three different meanings inside it. A desktop application can be free because it is open source and installed locally. A browser tool can be free because it runs without an account. A paid platform can offer a free plan that is genuinely permanent but deliberately narrow. Each model fails in a different way, and the failure usually appears weeks after the first chart is drawn.
Across nine pages analysed for this topic, the median page runs about 756 words and carries roughly 14 headings. Six of those pages include a list, five include FAQs, and only one includes a table. That pattern matters because most of the category is written as a feature tour rather than a decision guide. The gap worth filling is not another feature list. It is a clear account of what each free model actually costs in practice.
What "Free" Means in Free Gantt Chart Software
Three delivery models dominate the category, and each one places the cost somewhere different.
- Confirm the free tier has no expiry date, because a 14-day trial is not a free plan.
- Confirm the project cap and the user cap, since either one can end a rollout.
- Confirm which export formats the free tier allows, because a chart that cannot leave the tool is a locked chart.
- Confirm that dependency editing is not restricted, since task dependencies are the reason a Gantt view exists.
- Confirm whether an account, a download, or an internet connection is required to open the file.
- Confirm what happens to existing data if the plan changes or the account lapses.
- Confirm the free tier still works for a second project, not just the first.
That sequence is deliberately ordered by how expensive the discovery is. An expiry date found on day one costs nothing. A project cap found after a team has entered three months of scheduling data costs a migration.
Desktop apps that run without an account
GanttProject is the clearest example in the analysed set. Its own site describes it as a free desktop project scheduling and management app for Windows, Linux, and macOS, and the SourceForge listing describes a Java-based scheduling application featuring Gantt chart, resource management, calendaring, and import/export covering Microsoft Project, HTML, PDF, and spreadsheets. The same listing names the GNU General Public License version 3.0.
The trade-off is structural rather than commercial. A local-first desktop tool keeps project data on the machine, which suits confidential schedules and unreliable connections. It also means collaboration depends on file sharing rather than a shared live workspace, and the vendor's own site separates a cloud collaboration service from the desktop download. A team that needs two people editing the same timeline simultaneously is choosing the wrong model, not the wrong product.
Browser tools with no signup
OnlineGantt presents itself with the shortest possible promise: free online Gantt chart software, no signup, no download required, described as free forever. Ganttile takes a similar position, describing itself as a free online Gantt chart tool and answering "Is Ganttile really free to use?" directly in its FAQ, alongside features covering critical path, automatic project scheduling, and export and share.
The constraint here is durability rather than price. A browser tool with no account has no place to store a project except the browser itself, so clearing site data, switching machines, or changing browsers can end access to a chart that was never exported. The practical rule is to export after every meaningful editing session rather than at the end of the project.
Free Plans Inside Paid Project Platforms
The third model is the one most likely to be mistaken for a free product. ClickUp, Asana, monday.com, Wrike, Smartsheet, GanttPRO, TeamGantt, nTask, and Avaza all appear in the analysed roundups, and several of those pages organise their coverage around which tool is best for free Gantt charts specifically. GanttPRO's own page answers "Is GanttPRO a free Gantt chart software?" in its FAQ and offers a 14-day trial of premium features.
A 14-day trial and a free plan are different products. The trial exists to demonstrate the paid tier. The free plan exists to keep a small team inside the platform until the team grows past it. Both can be useful, but only one of them is still available next quarter, and the analysed evidence does not verify which named platforms run permanent free tiers versus time-limited trials. That distinction has to be confirmed on each vendor's own pricing page before any scheduling data is entered.
The second constraint is feature placement. In a paid platform, the Gantt view is often available on the free tier while the features that make a Gantt view useful are not. Dependency editing, critical path, workload views, and export are the usual candidates for the paid boundary. A free plan that shows a timeline but locks the arrows between tasks is a calendar with extra steps.
What free tiers usually limit
Five limits recur across the category, and each one has a different workaround cost.
Time. A trial expires on a fixed date. The workaround is to treat the trial as an evaluation window and export everything before it closes.
Seats. A free plan may cap the number of people who can edit. The workaround is to designate one scheduler and distribute the chart as a read-only export.
Projects. A free plan may cap active projects rather than users. The workaround is to archive completed projects rather than keeping them open.
Features. Dependency editing, critical path, and resource management are commonly gated. The workaround is to choose a tool whose free tier includes the one feature the project genuinely depends on.
Export. Some free tiers restrict which formats leave the platform. The workaround is to test the export on day one with a throwaway chart, before real data exists.
None of these limits is unreasonable on its own. The problem is that they are rarely stated together, so a reader comparing three tools is often comparing three different kinds of restriction.
How to Test a Free Gantt Chart Tool in One Afternoon
A single afternoon of structured testing answers more than a week of reading comparison pages, because the failure modes only appear once real scheduling data exists.
Start by building a chart with at least three linked tasks and one milestone. Task dependencies are the feature that separates a Gantt chart from a task list, so a tool that cannot express "this task starts after that one finishes" has already failed the test. Add a milestone and check whether it renders as a distinct marker rather than a zero-length bar.
Then test the boundaries in this order: export the chart to every format the free tier offers, open the exported file on a different machine, invite a second user if the plan allows it, and create a second project. Each step targets a specific limit. Export tests the lock-in boundary. The second machine tests the storage model. The second user tests the seat cap. The second project tests the project cap.
Finally, read the vendor's own pricing page rather than a roundup. Roundups describe what a tool can do. Pricing pages describe what the free tier will still do next month, and that is the question the category usually leaves unanswered.
Choosing between the three models
A solo planner working on confidential schedules is best served by a desktop application, because local storage removes both the account requirement and the connectivity requirement. A small team that needs a shared timeline and nothing else is best served by a browser tool, provided exports happen regularly. A team already inside a paid platform is best served by that platform's free tier, because the integration value outweighs the feature limits until the team outgrows the cap.
The edge case worth naming is the team that starts on a browser tool, outgrows it, and migrates to a paid platform mid-project. That migration is far cheaper when the original chart was exported in a format the new tool can import, which is why the export test belongs on day one rather than at the end.
Blackstone Intelligence builds search-ready page structures and content systems for Malaysian businesses, and its published case studies cover local SEO and AI-supported course development rather than project scheduling tools. The company's own guidance on this topic is limited to how pages are structured and how claims are verified, which is why this article names only tools that appear in the analysed competitor set and states no pricing, seat limit, or entitlement that a vendor page has not confirmed.
