FF Logs Viewer

FF Logs Viewer ingests FF Logs JSON exports or API responses to generate repeatable, objective performance metrics for Final Fantasy XIV raids. It targets raid leaders, theorycrafters, and data engineers who need reproducible summaries after a raid night or optimization sprints. The tool emphasizes accuracy, traceability, and exportable outputs, not UI rendering. It outputs structured data for downstream systems or reports. Typical use includes filtering to a boss and producing per-player DPS and per-ability contributions.
FF Logs Viewer normalizes data by encounter duration and party size, then computes totals such as damage, healing, and related rates (DPS, HPS). It provides per-player breakdowns (contribution by actor, rotation, buff uptime) and per-ability analyses (which skills moved the needle) with optional scope by boss or time window.
Outputs are designed for spreadsheet ingestion and dashboard integration, enabling cross-run comparisons and benchmarking. The tool differentiates itself through strict normalization, optional time-series slices, and automated data integrity checks, while gracefully flagging anomalies for transparency. Typical use cases include post-encounter reviews, raid-prep for subsequent nights, and patch-based benchmarking.
It supports local JSON and API modes, returning compact summaries plus detailed breakdowns and exporting to JSON or CSV for offline analysis.
