Download Firefly Helper
Use the helper if you want Windows to request admin permission, copy the Firefly lines, and open the hosts file for you automatically.
Windows Guide
Windows can connect through Firefly Helper or the manual hosts route.
The easiest route is Firefly Helper: run it as Administrator, let it copy the Firefly lines for you, open the hosts file automatically, save, and then launch Growtopia. If you want to do it fully by hand, the manual hosts method is still below.
Recommended: Firefly Helper
Works with standard Growtopia
Manual fallback included
Save the hosts file
Whether you use the helper or do it manually, the job is the same: save both Firefly lines at the bottom of the hosts file.
Flush DNS and launch Growtopia
The helper flushes DNS for you. If you do the manual route, launch Growtopia after saving and Windows should resolve to Firefly.
Switch method
Recommended: Firefly Helper
Firefly Helper is the easier Windows route. It asks for admin permission, copies the Firefly lines to your clipboard, opens the hosts file in Notepad, and flushes DNS after you save.
Download Firefly Helper
Download the helper script below, then run it. If Windows asks, allow it to run as Administrator.
Choose your language
The helper lets players choose English or Bahasa Indonesia before it continues.
Paste the Firefly lines when Notepad opens
The helper copies the two Firefly lines to your clipboard, opens the hosts file automatically, and tells you to scroll to the bottom and press Ctrl + V.

Save and let the helper finish
Save the hosts file in Notepad, close it, and the helper will flush DNS automatically. After that, open Growtopia and connect.
Note: Firefly Helper does not skip the hosts edit. It just makes the Windows route easier by handling admin access, clipboard copy, and DNS flush for the player.
Manual Windows hosts-file route
Use this if you prefer to edit the hosts file yourself without the helper script.
Open the hosts file path
Press Win + R, paste the path below, and open it with Notepad or another editor.
C:\Windows\System32\drivers\etc\hosts
Add the Firefly lines
Go to the bottom of the hosts file and paste both mappings exactly as shown here so the client resolves to Firefly. If you prefer, download the prepared text file first and copy from there.

Save with Administrator access if needed
If Windows refuses the save, reopen your editor as Administrator, apply the same change again, and then save it with elevated permission.
Launch Growtopia
Open the game normally. If the file was saved correctly, Growtopia should now connect to Firefly instead of the official server.
Note: To go back to the official server, remove the Firefly lines or add
# in front of them so they no longer apply.
