TaskJuggler review
A free, text-driven planner for complex schedules, resources, costs, and scenarios.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TaskJuggler is free, open-source project management software for technical planners handling complex schedules, resource assignments, costs, risks, and status tracking. Its optimizing scheduler calculates timelines and resource assignments from project constraints, while support for Gantt views, time sheets, calendars, and detailed reports covers the core needs of structured project planning. It runs on Linux, Windows, and macOS, and is operated primarily through the command line and text files using RubyGems.
The pricing model is straightforward: TaskJuggler is available at no cost as open-source software, with no paid tiers described. Its feature set includes automatic resource leveling, task conflict resolution, scenarios, baselines, working-hours and leave management, shifts, time zones, and task, resource, and account cost planning. Reports can be generated for interactive viewing, HTML publishing, calendars, status, accounting, and resource allocation. A built-in web server supports dynamic interactive reports, while CSV, iCalendar, Microsoft Project, and Clarity data exchange broaden its fit with established planning workflows.
TaskJuggler’s main trade-off is its operating model. Text files and command-line control offer precise, repeatable planning, but teams expecting a visual, browser-first workspace may find the workflow demanding. Integrations include Vim, Emacs mode, Emacs Org mode, FreeMind, Redmine, Bugzilla, Microsoft Project, and Computer Associates Clarity. Choose TaskJuggler when scheduling logic, resource balancing, what-if analysis, and cost visibility matter more than approachable collaboration features. Choose another project management tool if the priority is a conventional graphical interface for broad team participation.
