See how rare every achievement is Gratz! surfaces corpus-derived rarity on tooltips, in chat, and on the toast when you earn one.
Features
Midnight progress bar — an on-screen HUD tracking your progress through the curated Midnight achievement set, with your realm / region / global standing. Click to open the panel, drag to move, right-click to hide.

Gratz! panel (/gz) — the curated Midnight taxonomy with per-pillar progress, plus a live party/raid ranking: your current group, ladder-ordered by Midnight progress.
Rarity everywhere — every achievement tooltip, incoming guild/nearby chat announcement, and row in Blizzard's achievement panel gains a rarity line — Rarity: 3% of active accounts (Jun 2026) — colour-coded by how rare it is, so you can browse by rarity or just glance at what you're hovering.
Earned toast — when you earn an achievement, Gratz! shows a companion toast carrying its rarity, styled to be screenshotted as a share card (with an optional auto-screenshot on earn).

Passive rankings scan — quietly inspects players you cross paths with (party, target, mouseover, guildmates) to build your rankings corpus. Paced, never in combat, and fully optional.
One master switch turns the whole addon on or off; each surface above has its own toggle. Open options with /gz options or Settings → AddOns → Gratz!.
How the data works
WoW addons can't reach the internet at runtime, so every number ships baked in as a periodic snapshot. Each figure carries its own "as of" date, and every release is a fresh snapshot.
Privacy
Everything stays on your machine. Gratz! reads from Blizzard's own in-game API and keeps what it gathers in its local saved variables.
