AddOnQuietLogin is a lightweight quality-of-life addon that suppresses addon initialization and login messages from appearing in chat when you log in or reload the UI. (Can permanently block unwanted messages of your choice throughout gameplay in new options settings!)

Works for WoW Classic: Mists of Pandaria & TBC Anniversary.

Many addons print startup messages such as “loaded”, “initialized”, or version notices. AddOnQuietLogin keeps your chat clean by hiding most of this noise automatically, without affecting normal player, system, or combat messages. For any addon login messages that are not automatically hidden, use the options menu to block unwanted messages or use the slash commands below to supress seeing them on future logins. All messages are automatically suppressed for first 10 seconds upon entering world. If any unwanted messages slip through at login, add them to the block list, its bulletproof and will block any message or phrase throughout your entire login & gameplay experience that are from those pesky addon messages!

Block Mode Selector:

Choose how aggressive blocking should be:
Substring Blocks (Default) – Blocks matching messages at all times (Extremely Aggressive)
If your blocked text appears anywhere inside the message, it gets blocked.
Word Blocks – blocks chat messages during login/reload only
Your blocked text must appear as a separate whole word.

Whats the difference from substring blocks in the code and the word blocks?

Good question — this setting controls how strictly your Blocks match text.

Example — Substring Block:

"test"

Blocked messages:

This is a test
testing something
latest update

Why?
Because “test” exists inside those words.

Very aggressive
Good for addon spam / tags / prefixes
Can accidentally block normal chat depending on the text entered
(To help avoid accidentally blocking normal chat messages through a substring block, try adding the messages ecactly as they appear in the addon spam messages).
Example: "Gargul Version update 1.2.3.4 Use /gargul to open the menu".
(You should block the substring "/gargul" instead of just "gargul" to help it not block normal chat messages that may appear in normal chatusing the same word).
Addon chat suppression is pretty aggressive in default mode to help block those addon messages, but just be aware it may also block normal chat messages depending what your substring text is.

Example — Word Block:

"test"

Blocked messages:

This is a test
test complete

Allowed messages:

testing something
latest update

Why?
Because “test” is not a standalone word there.

Much safer for player chat
Prevents accidental filtering
Slightly less aggressive

Practical rule of thumb

Use substring for: Addon

Improved Message Suppression:

Enhanced targeted blocking:
New dynamic blockers work alongside them seamlessly
Always-On Suppression:
Fully suppresses multi-line initialization spam
Works even outside the login window
Survives addon updates (no file edits required)
Hard coded in the lua file, so it always blocks messages in the blocked list

Smarter & Safer Behavior:

Addon folder name auto-detection:
Prevents AddOnQuietLogin from detecting or muting itself
Compatible with both Classic and newer Settings UIs:
Automatically registers in whichever options system is available
No global chat hooks:
Remains ElvUI-safe and avoids chat taint issues

Quality of Life:

No more manual Lua edits:
Everything can now be managed in-game
Clearer control over noisy addons:
Easily fine-tune what gets hidden without affecting important messages

Known Limitations:

Some addons display messages during very early initialization, before other addons can intercept them. In these cases the login message must be disabled in the addon’s own options if available, (for example: BagSync, Attune). These addons have individual settings (in the Options > AddOns tab) that have specific checkboxes to enable or disable these messages from loading at login rather than blocking them at login with this addon enabled and may not be blocked by this addon alone unless they are added to the blocked list of addons. This is a limitation of the World of Warcraft addon loading system, not a bug, and further additions to the lua script would require old code that is no longer supported or against the rules.

Compatibility:

World of Warcraft Classic: Mists of Pandaria (5.5.3) & World of Warcraft Classic Anniversary Edition: The Burning Crusade (2.5.5)

Support:

This addon has been tested with most of popular addons and works perfectly with all of them to block unwanted login chat messages. Certain addons have been permanently blocked in the addon code upon logging in and can only be changed by disabling the AddOnQuietLogin addon or changing the hard lua code in the addon folder. If you encounter an issue or have a suggestion for any addon that is still loading unwanted chat messages, please open an issue or leave a comment on the project page.
