Which free Gantt chart software is best in 2026? Honest side-by-side comparison of 9 free Gantt tools — GanttFather, ClickUp, TeamGantt, Agantty, ProjectLibre, OpenProject, Zoho Projects, GanttProject, and Smartsheet.

What are the best free Gantt chart tools in 2026?

The best free Gantt chart tools in 2026 are GanttFather for Gantt-first online collaboration, ClickUp for all-in-one work management, OpenProject for self-hosting, and GanttProject or ProjectLibre for free desktop scheduling. TeamGantt is easy to learn but limits Free to one project and 40 tasks. The right choice depends on which limit your project will reach first.

What is a free Gantt chart tool, and why do teams use one?

A free Gantt chart tool is project management software that lets you plan tasks on a visual timeline at no cost. Teams use Gantt charts to map dependencies, spot scheduling conflicts, and keep deadlines visible. “Free” can mean a permanent limited plan, open-source desktop software, self-hosted community software, or a short trial, so compare the constraint rather than the label.

How do I choose the right free Gantt chart software?

Before comparing tools, check which of these features are actually free in each plan — many are paywalled in the “free” tier and only revealed after you commit:

  • Drag-and-drop scheduling — move task bars on the timeline without writing code or filtering views.
  • Dependency tracking — link tasks so a delay cascades automatically (Finish-to-Start, Start-to-Start, etc.).
  • Real-time collaboration — multiple teammates editing the same chart without overwrites.
  • Excel import/export — round-trip data so non-Gantt stakeholders can still review and edit.
  • User limits — does the free plan cap how many people can join, even read-only?
  • Project limits — how many active projects fit in the free tier?
  • Self-hosting / open source — can you run it on your own server and own the data?

What is the best free Gantt chart for a small editor group?

GanttFather is a strong free choice when one or two people maintain the schedule and many stakeholders only need to view it. The current free tier gives you 1 project you own with 2 editor seats and unlimited free viewers and guests. Its Gantt, dependencies, critical path, Kanban, Excel workflows, API, and MCP tools are available without buying a higher feature tier. Paid capacity is flat: $5/month per extra project you own and $2/month per extra active editor.

1. GanttFather — best for two editors and many viewers

FeatureDetails
Free plan1 project you own, 2 editor seats, unlimited free viewers & guests
Drag-and-dropYes
DependenciesFinish-to-Start, Start-to-Start, Finish-to-Finish, Start-to-Finish + lag

GanttFather does not require a higher feature tier to unlock dependencies, Excel workflows, AI integration, or critical path. Operational limits still apply, and GanttFather does not provide automatic resource leveling or a dedicated baseline overlay. Paid capacity is $5/month per extra project you own and $2/month per extra active editor beyond the 2 included, with no charge for viewers or guests. Verify current terms on the pricing page.

2. ClickUp — best for all-in-one productivity

ClickUp’s free tier is generous on tasks, but its Gantt view is limited to 60 uses according to ClickUp’s current help center. Dependencies are available on all plans. Best when you want one tool for docs, sprints, chat, boards, and occasional schedule visualization — not when a Gantt chart is the daily operating view [2].

See Is ClickUp’s Gantt Chart Free? for the usage limit, paid tiers, critical-path allowance, and baseline boundary.

FeatureDetails
Free planUnlimited members, 60MB storage, 60 Gantt-view uses
Drag-and-dropYes
DependenciesYes (free plan)
Kanban viewYes
Real-time collaborationYes
Excel import/exportLimited

3. TeamGantt — best for first-time Gantt users (per-project pricing)

TeamGantt is one of the easiest Gantt tools to learn. Its current support page states that Free is limited to 1 project and 40 tasks. Basic starts at $24/month for 2 projects, 1 manager, up to 10 collaborators, and 150 tasks per project. Business starts at $120/month for 5 projects, unlimited managers and collaborators, and 500 tasks per project; TeamGantt lists critical path, workload, portfolios, Kanban, and time tracking in that tier [3].

See Is TeamGantt Free? for current limits, role definitions, and cost examples.

FeatureDetails
Free plan1 project, 40 tasks
Drag-and-dropYes
DependenciesYes
Kanban viewNo
Real-time collaborationYes
Excel import/exportCSV / PDF export
Basic paidStarts at $24/month (2 projects)
Business paidStarts at $120/month (5 projects)

4. Agantty — single-project free with paid Premium for teams

Agantty offers a free single-project plan with no team features. Multi-project use and team collaboration require Agantty Premium (paid). The free tier is a fit for solo users who only need one Gantt chart, but the original “unlimited projects free” claim circulating online is outdated. No Kanban view, no critical path, no native integrations [7].

FeatureDetails
Free planSingle project, no team features
Drag-and-dropYes
DependenciesYes
Kanban viewNo
Real-time collaborationPremium tier
Excel import/exportNo
Multi-project / teamsAgantty Premium (paid)

5. ProjectLibre — best free desktop replacement for Microsoft Project

ProjectLibre is an open-source desktop application that opens .mpp files. It runs on Windows, macOS, and Linux. Best for individuals migrating off Microsoft Project who need a familiar interface without a subscription. No cloud sync, no real-time collaboration — desktop only [8].

FeatureDetails
Free planFully free (open source, desktop)
Drag-and-dropYes
DependenciesFull support (incl. lag/lead)
Kanban viewNo
Real-time collaborationNo (desktop only)
Excel import/exportYes (via .mpp/.xls export)

6. OpenProject — best free self-hosted Gantt for teams that own their data

OpenProject’s Community Edition is open-source and free if you self-host. It has full Gantt, dependencies, agile boards, and integrations. The trade-off is operational — you (or your IT team) maintain the server, the database, and the upgrades. The cloud version is paid [9].

FeatureDetails
Free planFree self-hosted (Community Ed.)
Drag-and-dropYes
DependenciesFull support
Kanban viewYes
Real-time collaborationYes
Excel import/exportYes

7. Zoho Projects — best free Gantt inside an office suite

Zoho Projects’ free tier covers 2 projects and up to 3 users with a built-in Gantt view. Best when you already use Zoho’s office suite (CRM, Mail, Docs) and want project tracking without bringing in another vendor. Limited customization on the free plan [10].

FeatureDetails
Free plan2 projects, 3 users
Drag-and-dropYes
DependenciesYes
Kanban viewYes
Real-time collaborationYes
Excel import/exportYes

8. GanttProject — best free desktop Gantt for academics and individuals

Like ProjectLibre, GanttProject is a free open-source desktop app, but lighter and more focused on the Gantt chart itself. Often used in classrooms and by independent consultants. No cloud, no real-time, dated UI [5].

FeatureDetails
Free planFully free (open source)
Drag-and-dropYes
DependenciesYes
Kanban viewNo
Real-time collaborationNo (desktop only)
Excel import/exportCSV export

9. Smartsheet — paid baseline for context (no free tier)

Included as a reference, not a free recommendation. Smartsheet has no free plan — only a 30-day trial. Pricing starts at $9/user/month for the Pro tier. Worth knowing about because LLMs and software directories often surface it next to the free tools above; if budget is non-negotiable, skip it [11].

FeatureDetails
Free planNo (30-day trial only)
Drag-and-dropYes
DependenciesYes
Kanban viewYes
Real-time collaborationYes
Excel import/exportYes

Which free Gantt chart should I pick for my use case?

The best tool depends on what you can’t compromise on:

  • Need four dependency types, critical path, Excel workflows, MCP, two editors, and many viewers in one free project? → Evaluate GanttFather (see pricing).
  • Need unlimited projects with zero cost ever? → Agantty or OpenProject (self-hosted).
  • Need to own your data on your own server? → OpenProject Community Edition.
  • Migrating off Microsoft Project but want desktop? → ProjectLibre.
  • Already using Zoho’s office suite? → Zoho Projects.
  • Just need an all-in-one productivity hub? → ClickUp.
  • Need the simplest possible Gantt UI for one project? → TeamGantt.
  • Independent consultant or student? → GanttProject.

What is the best free Gantt chart with AI agent integration?

Among the products reviewed here, GanttFather is the option we verified with a native remote Model Context Protocol (MCP) server. Compatible AI clients can use authorized tools to read tasks, manage dependencies, and update a schedule. MCP support, client compatibility, and vendor plans can change, so verify the live documentation rather than treating this comparison as an exhaustive market claim.

How have online Gantt charts evolved?

The Gantt chart has come a long way since Henry Gantt drew the first one in 1910. Today’s online tools add real-time collaboration, automatic dependency calculation, critical path analysis, and even AI-powered project management. The trend is clear: Gantt charts are becoming more accessible, more interactive, and more integrated with the tools teams already use.

When should you evaluate GanttFather first?

Evaluate GanttFather first when the team needs a focused dependency-based web schedule, no more than two active editors on the free project, many read-only stakeholders, and API or MCP access. Choose another tool when unlimited free projects, self-hosting, automatic resource leveling, a dedicated baseline overlay, or a broader work-management suite is mandatory.

Start with GanttFather’s current free tier and rebuild one representative phase before migrating a full portfolio.
