Why BlazonUI

A clear standard

Official servers only

We focus exclusively on Blizzard's Retail and Classic realms — cleanly built, openly documented, and maintained for the long run.

Built in the open

Open source on GitHub, a public roadmap, public bug reports. Anyone can follow along, weigh in, and contribute.

Community-driven

Features come from real community demand — discussed and prioritized together in Discord.

100% free

No premium tier, no subscription, no paywall — every tool and addon feature is open to everyone, for good.

The tools

No marketing copy — real tools

Every screenshot below is a real, live simulation or real live data from blazonui.de, not a mockup.

DPS Simulator

How much damage do you really do?

Enter a character name and your real gear and talents are pulled in automatically — powered by SimulationCraft. Test gear swaps, compare talent builds, measure against real Warcraft Logs numbers, compare with a guildmate.

Boss Guides

Every current boss, every role

Official Blizzard overview split by damage dealers, healers, and tanks, plus the boss's full loot pool — for Retail and Classic, always kept current for the active raid and dungeon tier.

Talent Planner

Build your spec, point by point

Class, hero, and spec trees side by side — prerequisites and row locks are checked automatically, exactly like in-game. Import a finished build straight into the game or test it in the simulator.

Retail & Classic

Retail

Current Expansion

Addons for the current Retail version — from interface polish to raid & Mythic+ features, built for the modern WoW API.

Classic

Classic & Classic Era

Dedicated addons for Classic realms — adapted to the older API and its own pace, instead of just carrying Retail features over 1:1.
