Top 10 Best Online Gantt Software of 2026

ClickUp’s Gantt view maps directly to tasks in a hierarchy, so creating a work breakdown structure is mostly about organizing the same task tree rather than maintaining a separate plan. A timeline can be adjusted by changing task start dates and durations, and predecessor links update dependent task timing in the schedule. Baseline capture supports schedule variance analysis so teams can see drift against the original plan rather than only observing the latest dates.

A tradeoff is that deep schedule analytics like earned value management and float calculation are not the core focus compared with tools built specifically for scheduling. ClickUp fits teams that want one place to run planning and day-to-day execution, where updating task dates in the Gantt view also updates status in their standard task workflows.

Instagantt is built around a visual schedule editor that keeps task hierarchy readable and keeps edits fast through direct manipulation. Dependency links update task dates across the chain so start and finish changes propagate through predecessor and successor relationships. Baselines let teams compare planned versus current progress, which supports schedule variance review during delivery cycles.

A tradeoff is limited depth for resource allocation and earned value management, so schedule control remains mostly schedule-centric instead of cost-and-resource centric. Instagantt works best when project leads need quick dependency changes, recurring task scaffolding, and baseline comparison for ongoing execution rather than deep portfolio governance.

Ganttic focuses on keeping Gantt updates actionable for teams by combining dependency-based scheduling with percent complete tracking and milestone handling. The editor supports bulk schedule changes through spreadsheet-style CSV import, and it maintains a baseline to compute schedule variance for clearer progress conversations. The collaboration layer is structured around projects and tasks rather than standalone chart publishing.

A key tradeoff is that deep portfolio-level governance features are thinner than in enterprise project management suites, so multi-program reporting may require workarounds. Ganttic fits teams that need recurring planning cycles, frequent Gantt edits, and dependable exports for status sharing to stakeholders.

GanttPRO brings browser-based Gantt chart planning with a focus on dependency-aware timelines and export-ready project reporting. Core capabilities include task hierarchy, percent complete tracking, baseline scheduling support, and schedule-variance visibility within the timeline.

GanttPRO also supports Microsoft Project file import and structured CSV import for bringing plan data in without manual re-entry. Timeline output is handled through PDF export and common sharing workflows for review cycles.

ProjectManager provides an online Gantt chart tied to broader work tracking, including milestones, tasks, and reporting views. The Gantt supports dependencies and a task hierarchy, which helps teams plan critical chains and identify schedule risk.

Integration depth focuses on importing work from Microsoft Project and exchanging data through CSV and export formats, which shortens onboarding for plan migrations. Admin control centers on team workspaces with permissioning for project access and audit visibility around changes.

TeamGantt is an online Gantt chart tool built around task-based planning for teams that want a visual schedule plus collaboration. It supports task hierarchy, milestones, and baseline schedule capture so schedule variance can be reviewed over time.

TeamGantt also includes dependency planning, file imports for Microsoft Project schedules, and exports for sharing timelines. The workflow is designed around keeping status in sync via structured task fields and recurring work patterns.

Smartsheet turns Gantt-style scheduling into an execution system by linking timeline tasks to sheet data, forms, and approvals. It supports task hierarchy with predecessors and successors, schedule views, and baseline capture to track schedule variance.

Automation rules can update fields from status changes, and its integrations extend project workflows beyond the timeline. The result is stronger governance for cross-team work where task records drive reporting and process steps.

monday.com adds Gantt-style planning inside a broader work management system, so timelines sit next to boards, dashboards, and workflows. The schedule experience supports task hierarchy, predecessor and successor links, and milestone and percent-complete tracking.

Teams can schedule work with calendar and timeline views, then keep delivery status synchronized through its status fields and automation rules. monday.com also offers data exchange through API access and file import and export options for cross-tool planning.

Wrike manages projects with a Gantt-style schedule view tied to tasks, assignments, and milestones. It supports task hierarchy through templates and structured work breakdown approaches, then updates the timeline when task dates and dependencies change.

Wrike also provides baseline planning features for schedule variance reporting and includes import and export options for Microsoft Project files and PDFs. Automation rules connect schedule events to workflow steps so timeline updates can trigger approvals, status changes, and notifications.

OpenProject is a web-based project workspace that renders an online Gantt chart tied to task management and milestones. It supports task hierarchies with dependency links and can calculate schedule impacts inside a shared schedule view.

Workflows include Kanban and calendar views, and the project plan can be exported for reporting and external review. For governance, OpenProject emphasizes project roles and audit trails so teams can track who changed timelines.
