About

GanttTool is a completely free, browser-based project management tool that lets users create professional Gantt charts without limits or signups. It uses PlantUML to generate clean, customizable diagrams, allowing teams to plan and visualize projects in just minutes. All data stays locally in the user’s browser, ensuring full privacy with no tracking or server storage. The tool supports tasks, milestones, dependencies, scheduling offsets, and project phases with smart cycle detection. Users can export charts as SVG or PNG or retrieve the full PlantUML code for flexibility. With features like auto-save, drag-and-drop reordering, resource tracking, and custom styling, GanttTool makes project visualization simple and accessible.

About

PHASI is web-based project-planning software for Engineering-to-Order and other complex technical projects. It connects a product or deliverable structure with relevant work phases on a shared timeline, so teams can plan engineering, procurement, manufacturing, assembly, testing, and other activities against specific components, assemblies, and project items. Reusable phase categories, timeline comments, and time tracking support day-to-day coordination. PHASI calculates Percent of Completion from completed relevant phases and configurable category weights, then rolls progress up through parent items and project structures. Engineering, manufacturing, and project-controls teams can use the workspace to review schedules, discuss work in context, and follow project readiness across custom machinery, industrial equipment, construction, infrastructure, and other structured delivery workflows.
