Viscosity — Flow, under control.
Viscosity is a script executor for Roblox, built around a calm, precise editor.
Release stage: In development
The Viscosity interface, in your browser
Every session starts at Home. Start a script, open a file or reopen a saved one.
The console lives under the editor. Tabs, line numbers and Luau highlighting.
Saved scripts stay in the library. Open any of them in a new tab.
Changes apply as you make them. Themes, density, font size and tab width.
What the interface does
All of this works in the window above. Items marked Planned aren’t built yet.
Editor
Luau syntax highlighting
A monochrome theme that separates keywords, strings, numbers and comments by weight and tone.
Multiple tabs
Open, close, rename and switch between scripts without losing your place.
Line numbers & current line
Optional gutter and a quiet highlight on the line you’re editing.
Adjustable type
Editor font size and ligatures, set once and remembered.
Workflow
Script library
Keep scripts in one searchable place and open any of them in a new tab.
Console
Info, warning and error lines in one list, in order, with a button to clear it.
Keyboard shortcuts
Open and close tabs and switch panels without reaching for the mouse.
Appearance
Three monochrome themes
Graphite, Carbon and Paper: the same interface in three intensities.
Density
Comfortable or compact spacing, depending on how much you want on screen.
