What is GanttTool?

GanttTool is an advanced yet completely free project management solution that helps users build polished Gantt charts using PlantUML without signups, limits, or watermarks. It runs entirely within the browser, relying on LocalStorage to auto-save progress so all project data remains private and never leaves the user’s device. The tool includes an intuitive interface for creating tasks, milestones, phases, and dependencies with real-time validation to detect cycles and scheduling conflicts. Its powerful timeline engine allows flexible planning through absolute dates, relative offsets, or chained task dependencies. Users can customize chart appearance by adjusting colors, fonts, and styles, making it useful for reports, presentations, and documentation workflows. GanttTool also supports resource allocation indicators, task notes, and hyperlink attachments to keep project context organized. Projects can be exported as high-quality SVG graphics, copied as PNG images, or downloaded as PlantUML code for further editing or automation. JSON import/export capabilities allow users to manage multiple project files effortlessly. The drag-and-drop system enables rapid task reordering, while non-working day logic enhances schedule accuracy. Altogether, GanttTool offers a surprisingly feature-rich Gantt chart experience that rivals paid tools while remaining free forever.

What is AxioPlan?

AxioPlan is a specialized project estimation tool created for delivery managers and agency project managers seeking quick answers to scope-related questions during client interactions. Rather than entering hours by hand, users assign each task a t-shirt size and a risk level. AxioPlan derives three-point PERT estimates from those inputs, calculates risk-adjusted totals using the Root Sum of Squares method, and generates P50, P85 and P95 delivery dates along with a cost breakdown organized by epic and role, removing the need to build or maintain estimation formulas. The platform's timeline functions in real time; any modification, such as removing an epic, changing team size or shifting a milestone, leads to instant recalculation of delivery dates and associated costs. Users can share a read-only link at any point before or during the call, allowing clients to access the live Gantt chart, the P85 delivery date and the continuously updated cost breakdown. This negates the need for tedious PDF recreations or follow-up emails, fostering a quick resolution during the call. AxioPlan also fits into the wider delivery stack. Existing Excel or CSV estimates can be imported and immediately become live, recalculating plans. Through its Claude connector, entire plans can be drafted or restructured in conversation, with each suggested change arriving as a reviewable diff that applies only once approved. When a bid is signed, epics, tasks, dates and statuses export straight into Jira Cloud. For quarterly and program-increment planning, a free PI planning board maps teams, iterations, features and cross-team dependencies, with live warnings for backwards dependencies and over-capacity teams. Tailored for digital agencies and software consultancies involved in fixed-price contracts, AxioPlan provides flat monthly pricing that allows for an unlimited number of team members.
