Description
Arcane Profiler
If your load screens feel like they're getting longer and you aren't sure which addon is the offender, Arcane Profiler gives you a millisecond-by-millisecond breakdown of what's happening behind the scenes.
Zero setup needed. Just install it, log in, and type
/ap (or click the minimap icon) to see your stats.Key Features
- Visual Load Timeline: A Gantt chart that plots every addon across your load window. Easily spot which addons load early, late, or in parallel.
- Slowest Addons at a Glance: A duration chart automatically sorted from longest to shortest load times.
- Side-by-Side Compare Mode: Open two load sessions side-by-side on the same millisecond scale. Disable an addon, hit
/reload, and immediately see how much time you saved with (+/-) delta badges. - Memory Tracking: Dedicated tab with a heat-mapped chart showing exact memory footprints per addon.
- Load Trends & Minimap Indicator: Keeps track of your last 20 sessions. The minimap icon glows green if your last load screen was faster than your previous login, and red if it got slower.
- Standalone HTML Viewer: Export your session data to view, filter, and compare load times outside the game in your browser.
- Quick Chat Output: Don't want to open the full UI? Use

FAQ & Compatibility
Does this hurt load performance?
No. It only reads internal timers and memory values that WoW already tracks automatically. Background overhead is practically zero.
Why do addons show 0ms?
Addons that load in the queue before Arcane Profiler finishes initializing won't have a starting timestamp. This affects only the first couple of addons in your load order.
Is it compatible with WoW Midnight?
Yes. Built specifically for Patch 12.0+ using modern
C_AddOns APIs. It doesn't touch restricted combat systems or use deprecated globals.The Arcane Profiler Team
