PROJECT PLANNING

See Your Project Dependencies at a Glance

Visualize task relationships and calculate critical paths instantly—no software to install, no learning curve.

Instant Critical Path Calculation

Add your tasks and dependencies, and the tool automatically identifies the critical path—the longest sequence of dependent activities that determines your project's minimum duration. No manual calculations, no formulas, no guesswork.

All Four Dependency Types Supported

Build accurate diagrams with Finish-to-Start, Start-to-Start, Finish-to-Finish, and Start-to-Finish relationships. Switch between dependency types with a simple dropdown—perfect for modeling complex real-world project constraints.

Export and Share Freely

Download your diagram as a high-resolution PNG, print-ready PDF, or JSON file for later editing. No account required, no watermarks on exports, no limits on how many diagrams you create.
