GanttPRO vs GanttProject 2026: Paid Cloud vs Free Open Source

GanttPRO vs GanttProject: what is the short answer?

Choose GanttPRO when your priority is dedicated cloud scheduling with mature baselines, critical path, and resource controls. Choose GanttProject when your priority is offline scheduling, local file ownership, and no subscription. Neither is universally better: the decisive questions are who needs to edit the schedule, whether critical path and baselines are required, and whether the surrounding workflow should be a focused scheduler or a broader work platform.

Verified August 7, 2026: Prices and plan packaging below were checked against the vendors’ official pricing and help pages. Prices are USD list prices for annual billing unless stated otherwise; taxes, promotions, regions, legacy plans, and negotiated contracts can differ.

How do GanttPRO and GanttProject compare now?

The table separates a visible timeline from formal schedule controls. A product can show dated bars while placing dependencies, critical path, or baseline comparison on a higher tier. That distinction matters more than whether a marketing page simply says “Gantt.”

When is GanttPRO the better choice?

GanttPRO is the stronger fit when the priority is dedicated cloud scheduling with mature baselines, critical path, and resource controls. GanttPRO is a cloud scheduler with assignments, comments, workload tools, imports, exports, and calendar integrations.

Its current scheduling position is also clear: A purpose-built Gantt chart is the core experience on every paid plan. Core includes dependencies and automatic schedule recalculation. Core includes critical path and float.

The main qualification is equally important. Every active user is a paid seat after the trial, and the visible starting price changes with the selected team-size band.

Choose GanttPRO if: its surrounding workflow matters as much as the chart, its current plan limits match the real editor group, and the team has tested one representative project rather than comparing feature names alone.

When is GanttProject the better choice?

GanttProject is the stronger fit when the priority is offline scheduling, local file ownership, and no subscription. The base desktop app is file-based rather than a built-in simultaneous multi-user cloud workspace.

For schedule buyers, the current entitlement is: The Gantt chart is the primary desktop planning surface on Windows, macOS, and Linux. The scheduler supports FS, SS, FF, and SF relationships plus positive or negative lag. The desktop product supports critical-path analysis.

The tradeoff is not hidden. Real-time browser collaboration, mobile access, and SaaS workflow automation are not part of the base desktop application.

Choose GanttProject if: its pricing unit matches how the team works, its scheduling tier contains every required control, and the product’s collaboration model fits internal and external participants.

What does the price comparison look like for 10 people?

• GanttPRO: At the current 10-member annual selector, Core is $960/year, Advanced $1,440/year, and Business $2,280/year.
• GanttProject: The desktop application is $0 for any team size, although coordination and file-sharing infrastructure are the team’s responsibility.

Those figures are not automatically like-for-like. A free viewer, collaborator, guest, manager, or desktop user can have different permissions in each product. Compare the smallest group that must actually create tasks, change dates, restructure dependencies, and administer the schedule—not the total number of people who may open a link.

For procurement, model at least three cases: the current editor count, the editor count after one year, and the number of simultaneously active projects. Then confirm the result in each vendor’s checkout because seat buckets, project add-ons, and regional pricing can change the total.

Which product has the stronger Gantt scheduling model?

GanttPRO: A purpose-built Gantt chart is the core experience on every paid plan. Core includes dependencies and automatic schedule recalculation. Core includes critical path and float. Core includes schedule baselines; higher tiers add collaboration, custom planning, workload, portfolio, and reporting depth.

GanttProject: The Gantt chart is the primary desktop planning surface on Windows, macOS, and Linux. The scheduler supports FS, SS, FF, and SF relationships plus positive or negative lag. The desktop product supports critical-path analysis. The desktop product supports project baselines and local project files.

A stronger schedule model is not always the better product. A team may rationally accept lighter Gantt controls in exchange for automation, documents, dashboards, or ecosystem fit. Conversely, a project manager who recalculates handoffs daily should not buy a broad platform merely because it can display a timeline.

What should you test before choosing?

1. Import or rebuild one real project with at least 30 tasks.
2. Create the dependency types the project actually uses, including lag if relevant.
3. Move a predecessor and confirm how successors react.
4. Display critical path and a baseline using the tier you intend to buy.
5. Invite one scheduler, one contributor, and one read-only stakeholder.
6. Export the schedule in the format your clients or PMO require.
7. Price the exact number of paid editors and active projects at checkout.

This test exposes permission, scale, and plan-limit differences that a marketing comparison cannot.

When is GanttFather a better fit than GanttPRO or GanttProject?

GanttFather is the simpler cost pattern when a project needs a Gantt-first workspace, no more than two included editors, and many reviewers. The free tier includes one owned project, two editor seats, unlimited viewers and guests, FS/SS/FF/SF dependencies with lag, critical-path highlighting, Kanban, Excel import/export, real-time sharing, REST API access, and a native MCP server.

The limits should be explicit: GanttFather does not currently provide automatic resource leveling or a dedicated schedule-baseline overlay. GanttPRO or GanttProject can be the better purchase when those capabilities, a larger ecosystem, or their specialized workflow outweighs the price difference.

Create a free GanttFather project and reproduce one dependency-heavy phase before deciding. For direct product pages, see GanttFather vs GanttPRO and GanttFather vs GanttProject.

Frequently asked questions

Is GanttPRO or GanttProject cheaper?

It depends on paid editors, active projects, and the feature tier. At the current 10-member annual selector, Core is $960/year, Advanced $1,440/year, and Business $2,280/year. The desktop application is $0 for any team size, although coordination and file-sharing infrastructure are the team’s responsibility. Compare the exact checkout totals rather than multiplying a headline price that may use a different team-size band or project bundle.

Which one has a usable free Gantt chart?

GanttPRO: There is no permanent free plan; new accounts receive a 14-day premium trial without a credit card. GanttProject: The desktop application is GPL3 software with an optional donation; free and paid downloads are functionally identical. “Free” should be evaluated with its usage, task, project, and collaboration limits—not just account creation.

Which one supports dependencies?

GanttPRO: Core includes dependencies and automatic schedule recalculation. GanttProject: The scheduler supports FS, SS, FF, and SF relationships plus positive or negative lag.

Which one supports critical path?

GanttPRO: Core includes critical path and float. GanttProject: The desktop product supports critical-path analysis.

Which one supports baselines?

GanttPRO: Core includes schedule baselines; higher tiers add collaboration, custom planning, workload, portfolio, and reporting depth. GanttProject: The desktop product supports project baselines and local project files.

How should a team migrate between them?

Export the smallest representative project first, preserve a copy of the source data, and validate task hierarchy, dates, dependency types, lag, assignees, comments, and custom fields after import. No cross-vendor migration preserves every permission, automation, dashboard, or integration, so budget time for manual reconstruction and acceptance testing.
