TaskJuggler as a Linux alternative to FastTrack Schedule
Updated
Our verdict
TaskJuggler can replace FastTrack Schedule for users who are comfortable with a text‑based workflow and don’t need a polished graphical UI. It covers the core scheduling, resource allocation and cost tracking functions, and it can generate Gantt‑style HTML reports. However, it lacks built‑in collaboration tools, native Excel/PDF export, and an interactive drag‑and‑drop Gantt editor, so teams that rely on those features will need work‑arounds or additional tools. For solo planners or technically‑savvy project managers who prefer scriptable definitions, TaskJuggler is a solid free alternative.

What works the same
- Both handle task scheduling and dependency management
- Both support resource allocation and leveling
- Both can calculate project costs and budgets
- Both can produce Gantt‑style visualisations (TaskJuggler via HTML)
- Both run on Linux and Windows
What is different
- FastTrack offers a full GUI with drag‑and‑drop Gantt editing; TaskJuggler uses text files and command‑line generation
- FastTrack exports directly to PDF, Excel and XML; TaskJuggler only outputs HTML (PDF via browser)
- FastTrack includes built‑in collaboration and shared‑project features; TaskJuggler has none
- FastTrack provides integrated portfolio management; TaskJuggler focuses on single‑project planning
- FastTrack is commercial with support; TaskJuggler is discontinued and community‑maintained
Opening your FastTrack Schedule files
FastTrack Schedule uses a proprietary file format; there is no documented importer for TaskJuggler, so direct opening is not possible. You would need to recreate the project in TaskJuggler manually or export FastTrack data to a neutral format like CSV/Excel and then convert it to TaskJuggler’s text syntax. The exact feasibility depends on the complexity of the original file.
Switching from FastTrack Schedule to TaskJuggler, step by step
- Export your FastTrack project to CSV or Excel if the option exists
- Map the exported columns to TaskJuggler resource and task attributes
- Create a new .tjp file following TaskJuggler’s syntax and paste the mapped data
- Run the TaskJuggler command‑line engine to generate HTML reports
- Verify schedules, resource loads and costs; adjust the .tjp file as needed
- If collaboration is required, set up a shared version‑control repository for the .tjp files
