RMFinder is an RPG Maker official tool for RPG Maker MV and MZ!(Only for Windows)
It can search your entire game for the following:

🍰 Items (receive/lose or sold in shop)
🔪 Weapons (receive/lose or sold in shop)
🐢 Armors (receive/lose or sold in shop)
🙋‍♀️ Actors (joining/leaving the party)
😈 Troops (Enemies)
📞 Calls to Common Events
💡 Switches (Conditions & set ON/OFF)
📈 Variables (Conditions & changing)
💬 Text Messages
🧚‍♂️ Script Calls
🏃‍♀️ Move Route Commands
🚲 Map Teleports

and display on which map and by which event they’re called. One could say RMFinder is an advanced Event Searcher.

What’s it good for?
This is useful if you want to find all instances of a healing potion in your game. Maybe you forgot where the party is supposed to find that important quest armor, or you want to check all maps where one enemy is appearing. The uses are plenty for a handy tool like this!

I wrote RMFinder for my own game because I’m revising many items and it was very hard finding all the places in the game where they’re actually used. So I put a lot of effort into this tool.
