All-in-One Free Viewer
Everything you need to
inspect P6 schedules
Professional-grade schedule analysis tools, completely free - no account required.
Use the viewer when a Primavera P6 XER file needs a fast schedule check before it is imported, shared or discussed. The page parses the selected XER file locally, renders activities against the WBS hierarchy and gives planners direct access to Gantt bars, milestones, progress, total float, critical activities, relationship lines, zoom levels and activity detail without creating an account or installing desktop software for quick programme review and planning meetings with the project team.

Full Gantt chart with task bars, progress indicators, milestone diamonds and resizable split panel. Zoom between day, week and month views.
WBS Hierarchy
Activities organized by the Work Breakdown Structure from your P6 schedule with full path display and tree navigation.
Critical Path
Critical activities highlighted in red with total float analysis. Toggle critical path view to focus on schedule-driving activities.
Dependency Lines

Activity Search
Instantly filter activities by ID, name or WBS path. Find any activity in schedules with thousands of tasks.

100% Privacy
Your XER files are parsed entirely in your browser using JavaScript. Nothing is uploaded to any server - your schedule data stays private.
