PHANTOM runs as many Roblox clients side by side as your PC can handle. It watches them, brings crashed and kicked accounts back and locks your logins in a vault only you can open.

No placeholders: every feature talks directly to Roblox and Windows.
As many Roblox windows as you like at the same time. PHANTOM takes over the Roblox lock automatically.
AES-256 encryption, a recovery key and automatic backups that only you can open.
Sign in on roblox.com in its own window, or add many accounts at once from a cookie list or .txt file.
Just type “Pet Simulator 99”. PHANTOM searches like the Roblox search bar and shows icon, creator and player count.
After a crash, kick, lost connection or frozen window the account joins again on its own.
Ghost mode at 15 FPS, CPU limit per alt, memory trimming, muted alts. Your main window stays smooth.
Every public server with players, ping and FPS. One click sends your accounts into exactly that server.
Any window freely down to 160 px wide, without title bar, tiled automatically. Smaller than Roblox normally allows.
New version? One click in PHANTOM installs it. Crashes and kicks are posted to your Discord channel, anti-AFK prevents the 20-minute kick.
PHANTOM recognises whatever you paste and shows you where it goes before launching.
A Roblox login is worth as much as the password. That is why PHANTOM never leaves them lying around.
Extreme mode turns down everything an alt does not need. The overload guard only launches new accounts when enough memory is free, so your PC stays smooth. PHANTOM shows live how many more alts fit.
| Memory | Alts (estimate) |
|---|---|
| 8 GB | 6 to 10 |
| 16 GB | 15 to 25 |
| 32 GB | 40 to 60 |
| 64 GB | 100+ |
Download PHANTOM-Setup.exe and open it. Windows may show “Windows protected your PC” because PHANTOM has no paid code-signing certificate yet. Click More info → Run anyway. Setup needs no admin rights and creates Start menu and desktop shortcuts.
On first start you choose a master password (at least 8 characters). PHANTOM then shows your recovery key. Write it on paper or store it in your password manager, not as a file on the same PC.
For several windows to work, PHANTOM has to be there before Roblox. Close all Roblox windows, including the tray icon. PHANTOM then shows “Multi-Instanz aktiv” in green at the top left. Best close other alt managers.
Konten → Konto hinzufügen (Accounts → Add account) opens the real Roblox login page. Sign in, done, the window closes itself. Many accounts at once: Cookies importieren, one line per account or pick a .txt file. Every cookie is checked with Roblox.
On Spielen (Play) click the accounts, type the game name (or paste a link) and press start. PHANTOM launches the accounts one after another a few seconds apart. Live shows every client with CPU, RAM and status.
Open Tresor (Vault) and click the account. PHANTOM checks it live with Roblox and shows what is wrong: signed out, banned or kicked, with the exact history. Neu anmelden renews the login, Im Browser öffnen takes you straight to roblox.com as that account.
Leistung (Performance): pick a profile, e.g. “Extrem · 100+” for lots of alts. Automatik → Fenster: mini and borderless windows. Automatik: auto-rejoin, anti-AFK, window grid. Discord-Meldungen: add your webhook. Panic key Ctrl + Shift + F12 closes all clients instantly.
For Windows 10 and 11 (64-bit). PHANTOM installs updates itself with one click.
Having several Roblox accounts is allowed. Individual games can forbid multi-accounting in their own rules, so follow them. PHANTOM does not modify any game and does not hook into Roblox, it launches Roblox the same way the Roblox website does.
Open the vault with your recovery key and set a new password. Without password and recovery key nobody can get at the stored logins, not even us. Your Roblox accounts themselves of course stay, you would just have to sign in again.
Install PHANTOM, choose “I already have a vault backup” on the vault screen, pick the newest .phantomvault file from your backup folder and enter your password or recovery key. Tip: put the backup folder on a USB stick or in OneDrive (Settings).
Windows SmartScreen warns about programs without a purchased code-signing certificate. Compare the SHA-256 checksum above with your file (PowerShell: Get-FileHash .\PHANTOM-Setup.exe) to know it is unchanged.
Roblox was already running before PHANTOM started. Close all Roblox windows and the Roblox tray icon. After a few seconds the indicator turns green. If another alt manager runs, it holds the lock. That works too, but one program is better.
With extreme mode about 300 to 500 MB of memory per alt. PHANTOM shows live under “Leistung” how many more fit, and the overload guard stops it from getting too many.
Unfortunately not. Roblox needs Windows with graphics, and free always-on servers (e.g. Oracle or Google free tier) are small Linux machines. What works for free: use an old second PC or laptop as an “alt machine” and run PHANTOM there.
Click the account in the vault. You instantly see whether the login is valid, whether the account is banned, and the full history. “Im Browser öffnen” signs you in as that account on roblox.com in its own window.
Windows Settings → Apps → Installed apps → PHANTOM → Uninstall. You are asked whether to delete your accounts on this PC. Your vault backups are always kept.
