WoW Insights tracks World of Warcraft PvP meta in real time. It analyzes live leaderboard data from US and EU servers to show what the best players are actually using — gear, enchants, gems, talents, and stat priorities — broken down by spec and bracket.

• BiS Gear — Most popular items per slot for any spec and bracket (2v2, 3v3, Solo Shuffle, Blitz)
• Enchants & Gems — Top enchant and gem choices with usage percentages
• Talent Builds — Full talent tree visualization with top build highlighted and per-node usage stats
• Stat Priority — Median stat distribution from top-ranked characters
• Top Players — Leaderboard of highest-rated players per spec, linkable to their full profile
• Class Tierlist — Meta ranking of all specs by bracket and role, with presence and win rate scores
• Character Profiles — Individual character pages showing their current equipment and talent loadout
• Spec Particle Effects — Canvas-based visual effects per spec (snow, blood, plague, venom drip, shadow smoke, etc.)
• WebGL Background — Custom raw WebGL FBM noise shader with ember particles on the homepage
• Localization — English and Spanish (Latin America) support

• Next.js 16 — App Router, React Server Components, Suspense streaming
• React 19 with React Compiler
• TypeScript
• Tailwind CSS v4 + shadcn/ui + Radix UI
• Vitest + Storybook 10
• Raw WebGL (no Three.js)
