GanttPRO vs TeamGantt vs Smartsheet: 3-Way Comparison (2026)

Which is better: GanttPRO, TeamGantt, or Smartsheet?

GanttPRO is the strongest pure scheduler for a team whose members all need equal access. TeamGantt is usually the cheapest when one manager builds a few schedules for many collaborators. Smartsheet is best when the Gantt chart must live beside formulas, forms, reports, and automated operational workflows. The right answer depends on who edits and what must be controlled.

GanttFather publishes competing Gantt software, so this is a competitor comparison. Every mutable price and plan claim below is linked to the vendor’s own documentation, and the differences—including features GanttFather does not match—are stated directly.

Pricing and features verified: August 7, 2026. Prices are public USD rates before tax; GanttPRO’s per-user rate changes with selected team size.

What is the short verdict for each tool?

Fast rule: choose GanttPRO for scheduling depth, TeamGantt for role-efficient pricing, and Smartsheet for spreadsheet-style work management.

How do GanttPRO, TeamGantt, and Smartsheet compare feature by feature?

Feature labels are not always equivalent. For example, a Smartsheet member can build grid logic and schedules, while a TeamGantt collaborator has narrower project-control rights than a manager. Compare permissions, not just the presence of a checkmark.

Which tool has the best Gantt scheduling features?

Why GanttPRO wins for schedule mechanics

GanttPRO’s Core plan includes the controls a formal scheduler reaches for first: four dependency types, lag and lead, automatic rescheduling, critical path, float, milestones, calendars, and baselines. Its knowledge base explicitly describes total and free float, while the Core plan also supports history and Microsoft Project import.

That combination is unusually complete at the entry tier. It is the best of these three when the weekly job is to maintain a logic-driven schedule rather than merely display dates.

Where TeamGantt is simpler

TeamGantt is easier to price and operate when one person owns the chart and collaborators mostly update assigned work. Basic provides the core Gantt surface at a low annual bundle price. Its Business tier adds critical path, workload, portfolio management, actual-versus-estimated timelines, advanced dependencies, and time tracking.

The trade-off is a large tier jump: Basic is $240 annually, while Business starts at $1,140 annually. A team needing critical path should compare Business with GanttPRO Core—not compare Basic price with GanttPRO features.

Where Smartsheet is deeper than it looks

Smartsheet is sometimes dismissed as a colored spreadsheet, but its official help center documents automatic predecessor scheduling, critical path, driving path, summary path, four predecessor relationship types, milestones, hierarchy rollups, and project calendars. Its Gantt view is a capable scheduler.

Smartsheet’s advantage is everything around that schedule: formulas, cell linking, reports, dashboards, forms, and automation. Its disadvantage is configuration. Owners or admins must enable dependencies and map the correct start, end, duration, predecessor, and percent-complete columns.

For a focused two-way analysis, see GanttPRO vs TeamGantt, GanttPRO vs Smartsheet, and Smartsheet vs TeamGantt.

How much do the three tools cost for ten people?

The table uses annual billing and public list prices. Because TeamGantt prices projects and roles rather than ten identical seats, two valid TeamGantt scenarios are shown.

GanttPRO’s public calculator charges ten-person teams $8 per user/month for Core, $12 for Advanced, and $19 for Business when billed annually. The lower $7/$10/$17 rates visible on its landing page apply at the selected 20-member discount band, so using them for ten users would understate the total.

Which is best for collaboration?

Choose TeamGantt when collaboration means one scheduler publishing a clear plan while contributors update status, comments, checklists, and files. Its role distinction is deliberate and cost-effective for that pattern.

Choose Smartsheet when collaboration includes intake forms, row-level data, formulas, approvals, reports, and dashboards. Pro includes unlimited Contributors; Business adds unlimited Guests and richer administrative capabilities.

Choose GanttPRO when collaboration happens inside the schedule itself. Comments, attachments, notifications, shared links, and task assignment are present, but the product is less suited than Smartsheet to building a general operational database around the project.

Which is best for portfolios and resources?

All three reserve their strongest multi-project and resource features for higher plans:

• GanttPRO Business adds workload, portfolios, reports, budget planning, and time tracking.
• TeamGantt Business adds workload, portfolios, team resourcing, hourly estimates, and time tracking.
• Smartsheet Business adds workload tracking and Timeline; Enterprise adds the currently advertised Portfolios capability.

Do not choose from a marketing label alone. Test one real allocation conflict: assign the same specialist to overlapping tasks in two projects and check whether the view exposes the overload in the way your manager needs.

When should you choose none of these?

None is the universal answer:

• Choose Microsoft Project when deep desktop scheduling, enterprise governance, and Microsoft-specific portfolio workflows are required.
• Choose GanttProject when local files, offline work, and zero license cost matter more than real-time cloud collaboration.
• Choose ClickUp or Asana when task workflow, documents, messages, and automation dominate, with Gantt as a supporting view.

How should you run a fair trial?

Use the same 30- to 50-task project in every product:

1. Import or enter the same work breakdown structure.
2. Add at least one FS, SS, FF, and SF dependency plus a lag.
3. Save a baseline, then delay an upstream task by three days.
4. Check whether downstream dates, critical path, and variance respond as expected.
5. Invite one schedule editor, one task contributor, and one read-only stakeholder.
6. Export the result in the format your sponsor actually consumes.
7. Price the exact roles and project count needed after the pilot—not a generic ten-seat bundle.

When is GanttFather a better fit than all three tools?

GanttFather fits when a small scheduling group needs the dependency network—not a portfolio suite or operational database—to remain the center of the workflow. The free tier includes one owned project, two editor seats, and unlimited viewers and guests; the application supports FS/SS/FF/SF dependencies plus lag, critical path, Excel import/export, and real-time sharing. Compatible AI agents can also work through MCP without requiring a custom integration.

It is not a direct substitute for GanttPRO’s float and baseline depth, TeamGantt’s construction workflow, or Smartsheet’s formulas and automation. It also does not automatically resource-level schedules or provide a dedicated baseline overlay. Compare those trade-offs directly in GanttFather vs GanttPRO, GanttFather vs TeamGantt, and GanttFather vs Smartsheet.

Create a free GanttFather project and run the same 30-task trial before choosing a paid platform.

Frequently asked questions

Is GanttPRO cheaper than TeamGantt?

Not when one TeamGantt Basic manager can serve the whole team: Basic is $240 annually, versus $960 for ten GanttPRO Core users. GanttPRO Core is cheaper than TeamGantt Business ($1,140) for ten users and includes more schedule-analysis features at entry level.

Is Smartsheet better than GanttPRO for Gantt charts?

GanttPRO is quicker for dedicated schedule building and exposes float directly. Smartsheet is better when the schedule must integrate with formulas, forms, reports, dashboards, and broader operational data.

Does TeamGantt include critical path?

Yes, but TeamGantt’s current public comparison groups critical path with Business rather than Basic. Verify the live matrix before purchasing.

Does Smartsheet calculate critical path?

Yes. With dependencies enabled, Smartsheet can highlight critical path and also offers driving and summary paths. Its official help center lists this for Pro, Business, and Enterprise.

Does GanttPRO have a free plan?

No ongoing free plan is advertised. GanttPRO provides a 14-day fully featured trial without requiring a credit card.

Which tool is easiest for spreadsheet users?

Smartsheet. Its grid, formulas, row hierarchy, conditional formatting, and reports retain a spreadsheet mental model while adding schedule logic.
