About This Tool

FFLogs Viewer converts raw combat logs into structured performance metrics to help raid teams evaluate boss fights and rotations. It emphasizes actionable insights over raw data, enabling rapid hypothesis testing and decision-making for raid nights.

Conceptually, the tool queries the FFLogs API for a selected region, server, character, and time window, aggregates events per participant, and computes DPS, HPS, and a per-spell breakdown. It aligns data to boss phases and fight durations, then surfaces top contributing abilities and rotation patterns. Users can compare multiple runs or players to identify stability or variance in performance.

Common use cases include validating a new rotation, benchmarking gear or talents, and diagnosing a DPS check failure. The system exports results to CSV/JSON for offline analysis or sharing with raid members. Unique value lies in cross-run comparisons, saved queries, and support for private vs public data visibility where applicable. It is designed for raid leads, DPS analysts, and theorycrafters who need precise, exportable metrics rather than qualitative summaries.

Frequently Asked Questions

Find Quick Answers

What data sources does FFLogs Viewer use?

FFLogs Viewer relies on publicly available data from the FFLogs API. Private logs are not accessible through the viewer, and results reflect only data the user has permission to view in FFLogs.

Can I compare multiple fights or players?

Yes. The tool supports loading and comparing multiple runs or players within the same window. You can observe DPS trends, rotation stability, and spell usage across fights to identify consistent patterns.

How are DPS numbers calculated?

DPS is calculated as total_damage divided by the fight duration in seconds for the selected window, with per-player contributions aggregated and surfaced in the top-spells breakdown.

What export formats are available?

Exports are available in CSV and JSON formats, enabling easy integration with spreadsheets, databases, or theorycrafting pipelines.
