Why Most "Online Viewers" Put Your Schedule at Risk
Understanding the critical difference between legacy cloud viewers and XER Reader WebAssembly architecture.
Server-Side Upload Model
Conventional web tools require you to transmit your schedule file to their remote cloud servers. Once uploaded, your project data is vulnerable:
- Schedules stored indefinitely on unknown third-party servers
- Violates enterprise confidentiality, NDAs, and defense regulations
- Slow upload speeds and timeouts on 50MB+ schedule files
Client-Side In-Memory Sandbox
XER Reader processes your project schedules directly inside your browser. All parsing and calculations run locally in memory:
- Files stay 100% on your machine in local browser RAM
- Fully compliant with enterprise data protection standards
- Instantaneous loading even on massive 50,000+ activity projects
Desktop Power Inside Your Web Browser
No software installation required. Access all essential schedule inspection tools directly online.
Drag-and-Drop Ingestion
Simply drag and drop any Oracle Primavera P6 .xer or P6 XML file into the browser window. The file parses directly inside your local browser memory without server bottlenecks.
Full Synchronized Gantt
Explore activities and the Gantt timeline in perfect synchronicity. Adjust timescale zoom from individual shifts up to multi-year program overviews.
Critical Path & Float Analysis
Instantly highlight driving critical path activities, inspect total float, free float, and review relationship logic with predecessor and successor arrows.
WBS Filtering & Search
Drill down through the Work Breakdown Structure with an intuitive WBS drawer. Apply Excel-style column filters and instant activity code searches.
Baseline Comparisons

Password-Protected Sharing
