PlotMor Launcher: run many Roblox accounts side by side
A Windows launcher for running multiple Roblox accounts side by side, with per-instance performance control and executor and version management. Windows 10 / 11 (x64), accounts stored locally and encrypted, source code on GitHub.
Accounts
Sign in with Roblox or paste a cookie. Launch, watch live presence, kill instances and act on a whole selection at once.
Groups
Bundle accounts and launch the whole set with one click, with a performance preset for the group.
Mixer
Set graphics level, FPS cap, a hard RAM limit and volume for every running client, per instance.
Executors
Manage your executors and track which Roblox version each one supports, then install it with one click.
RDD
Browse and download Roblox deployments straight from the CDN and keep several builds side by side.
Swap
Clean Roblox traces and change machine identifiers between sessions, with a backup and a restore.
Anti-AFK
A native helper taps each Roblox window before the idle kick, background windows included.
Auto-rejoin
If a launched account is kicked or disconnects, it relaunches into the game it was playing, up to three tries.
Themes
Presets, accent colour, surface brightness, corner radius, interface scale and reduce-motion.
Your accounts stay on your machine
Encrypted at rest
Account data is protected with AES-256-GCM using a key derived from your own encryption key.
No PlotMor server
Nothing is uploaded to a PlotMor-operated server. The app talks to Roblox itself and to the version API.
Sandboxed window
The interface has no direct system access. Every capability is an explicit, auditable channel.
Source on GitHub
The code is public at github.com/kere0ne/plotmor under launcher/, so you can check how accounts and cookies are handled before you run it.
Launcher FAQ
Can I really run several accounts at the same time?
Yes. A native helper holds the singleton mutex Roblox normally uses to allow only one client, so several clients run side by side, each with its own FPS cap, graphics level, RAM limit and volume.
Where do I get it?
Build it yourself from the source in the repository with the included build scripts, or run it in development with npm and electron. No compiled installer ships from this site yet.
Is it affiliated with Roblox?
No. It is an independent tool. Multi-instancing, idle keepers and machine-identifier changes can go against the Roblox Terms of Use. You use it at your own risk and discretion.
