GanttProject vs Smartsheet
A side-by-side editorial comparison of GanttProject and Smartsheet — release velocity, themes, recent moves, and the top alternatives to consider.
GanttProject vs Smartsheet: at a glance
What is GanttProject?
GanttProject 3.4 is in its sixth beta, filling gaps users have asked about for years.
GanttProject is a Java desktop scheduler with major versions one to three years apart. The 3.4 Beta VI build in September added custom properties in filters and calculated columns, clickable links in the task table, multi-file import and a manual token path for GanttProject Cloud sign-in. A 3.3 release page dated 8 November restates 3.3's highlights (SQL-calculated columns, project-relative week numbers, native Apple Silicon) with an updated bundled Java runtime.
What is Smartsheet?
Smartsheet becomes where plans drafted in Claude Sheets get executed.
Smartsheet is rebuilding its core around table view: a table view report builder, Enterprise sheets above 500,000 cells, reports above 1,500,000 rows and a new Gantt view with critical path. On November 10 it added a beta that sends a plan started in Claude Sheets into Smartsheet, ready for a team to act on. Earlier it retired card view for Enterprise and limited AI to Table, Board and Timeline views.
GanttProject vs Smartsheet: editorial side-by-side
GanttProject 3.4 is in its sixth beta, filling gaps users have asked about for years.
◆ Current state
GanttProject is a Java desktop scheduler with major versions one to three years apart. The 3.4 Beta VI build in September added custom properties in filters and calculated columns, clickable links in the task table, multi-file import and a manual token path for GanttProject Cloud sign-in. A 3.3 release page dated 8 November restates 3.3's highlights (SQL-calculated columns, project-relative week numbers, native Apple Silicon) with an updated bundled Java runtime.
◆ Where it's heading
3.3 introduced SQL-driven calculated columns; 3.4 makes them useful with custom properties and puts more data on the chart itself. Cloud sign-in keeps getting workarounds, so the cloud tie-in from 3.0 is still part of the plan.
◆ Prediction
A 3.4 release after six betas is the obvious next step, but the project's slow cadence makes timing hard to call from the entries.
Smartsheet
5.0COLLABPM
Smartsheet becomes where plans drafted in Claude Sheets get executed.
◆ Current state
Smartsheet is rebuilding its core around table view: a table view report builder, Enterprise sheets above 500,000 cells, reports above 1,500,000 rows and a new Gantt view with critical path. On November 10 it added a beta that sends a plan started in Claude Sheets into Smartsheet, ready for a team to act on. Earlier it retired card view for Enterprise and limited AI to Table, Board and Timeline views.
◆ Where it's heading
Two tracks are visible. The core product is consolidating onto fewer, larger views, and Smartsheet is positioning itself as the execution layer for work drafted elsewhere, starting with an AI spreadsheet. Imports from SharePoint and Workday sync point the same way: pull data in, run the work in Smartsheet.
◆ Prediction
Expect the Claude Sheets handoff to leave beta and similar send-to paths from other AI assistants, since the release frames Smartsheet as the destination rather than the drafting tool.
