Project Scheduling Software That Does the Heavy Lifting
LoopGantt is free project scheduling software built on the Critical Path Method. It automatically calculates your critical path, cascades dependency changes in real time, and respects your work calendar — so you can focus on managing your project instead of maintaining a spreadsheet.

Scheduling Features That Actually Matter
Real-Time CPM Engine
LoopGantt performs forward and backward pass calculations on every change. Move a task, and the entire schedule recalculates instantly. The critical path updates in real time, so you always know which tasks are driving your project end date. Early start, late start, early finish, late finish, and total float are all computed automatically.
Dependency Cascading
When you drag a predecessor task to a new date, all downstream tasks cascade automatically. LoopGantt respects all four dependency types (FS, SS, FF, SF) and handles complex dependency chains without breaking your schedule. No more manually updating 30 tasks because one meeting moved by a day.
Calendar-Aware Scheduling
Define your work week, add holidays, and LoopGantt will schedule around non-working days automatically. A 5-day task that starts on Thursday will finish the following Wednesday, not Monday. Pro users can create multiple calendars for different teams or resource types, each with their own working patterns.
AI-Powered Generation
Don’t want to build your schedule from scratch? Describe your project in plain English and let the AI create it. LoopGantt’s two-pass AI generates tasks, estimates durations, creates logical dependencies, and structures everything into phases. You get a professional schedule as a starting point — then customize with drag-and-drop.

Frequently Asked Questions
What scheduling methodology does LoopGantt use?
LoopGantt uses the Critical Path Method (CPM), the industry-standard scheduling methodology used in construction, software development, engineering, and event planning. CPM calculates the forward and backward pass through your network of tasks to determine the earliest and latest start/finish dates, total float, and the critical path. This is the same methodology used by tools like MS Project and Primavera P6 — LoopGantt simply makes it accessible without the enterprise learning curve.
How does Critical Path Method work in LoopGantt?
When you create tasks and define dependencies, LoopGantt automatically performs CPM calculations in real time. It identifies the longest path through your project network — the critical path — and highlights it on the Gantt chart. Tasks on the critical path have zero float, meaning any delay directly pushes out the project end date. Non-critical tasks display their available float so you know exactly how much schedule slack exists. Every time you move, resize, or re-link a task, the critical path recalculates instantly.
Does LoopGantt support all four dependency types?
Yes. LoopGantt supports all four standard dependency relationships: Finish-to-Start (FS), Start-to-Start (SS), Finish-to-Finish (FF), and Start-to-Finish (SF). The most common type is Finish-to-Start, where one task must finish before the next can begin. You can create dependencies by clicking between tasks on the Gantt chart. Each dependency is reflected in the CPM calculation and the critical path analysis.
Can LoopGantt handle custom work calendars and holidays?
Pro users can configure custom work calendars that define working days, non-working days, and specific holidays. The scheduling engine respects these calendars when calculating task durations and dates — if a task spans a holiday, it automatically extends to account for the non-working day. This ensures your schedule reflects real-world working patterns. Free users get a standard Monday-through-Friday calendar with weekends off.
Is LoopGantt suitable for small teams?
LoopGantt is designed specifically for individuals, freelancers, and small teams who need professional scheduling without enterprise complexity or cost. The free tier supports up to 5 projects with unlimited tasks per project — more than enough for most small team needs. There is no per-seat pricing, so your entire team can view and reference the same schedules. The Pro plan adds unlimited projects, baselines, custom calendars, and premium export formats for teams that need more.
