gantts.app review
A focused, free Gantt planner with strong export options and no account requirement.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
gantts.app is a free, browser-based Gantt chart maker for individuals and teams planning projects without creating an account. Its interactive timeline supports drag-and-drop scheduling, task resizing, dependencies, milestones, project phases, roll-up bars, and completion-percentage tracking. The product is a good fit for project planners who need a focused visual schedule, particularly when offline access and polished deliverables matter.
The product has a straightforward pricing model: it is free, with no paid tiers, trial, or credit card requirement. Users can create unlimited tasks and projects, save work locally in the browser, and continue working offline. CSV and JSON imports can help start a project from an existing task list, while exports to PDF, PNG, Excel, and PowerPoint support sharing and presentation. Because projects are stored locally, teams should consider whether that workflow fits their collaboration and information-management needs.
Its strongest planning feature is the combination of four dependency relationship types and automatic critical-path calculation with highlighting. Milestones, phases, roll-up bars, and progress tracking add useful structure without moving beyond the core Gantt-chart job. The trade-off is a narrow scope: gantts.app does not cover resources, workload management, baselines, or integrations. Choose it for independent planning and self-contained project schedules; choose an alternative when capacity planning, baseline comparison, connected workflows, or broader project-management controls are requirements.
