Everything you need to analyse a P6 schedule
Four powerful views and analysis tools, all running locally in your browser
from a single .xer file upload.
Network Diagram
View activities and their logic links as a precedence network, visualising dependencies and the overall schedule flow.
Critical Path Highlight
Activities on the critical path are instantly colour-coded in red, so schedule risks are visible at a glance across both views.
Path Finder
Enter a start and end activity ID to trace and highlight every path between them — essential for logic review and what-if analysis.
Search & Filter
Search by activity ID or name to instantly locate and highlight nodes. Filter to critical activities only with a single toggle.
Print & Export
Print the full network diagram or the current viewport. Tile large diagrams across multiple pages for physical review sessions.
