What Ionize gives you

The product, item by item.

A Windows scripting environment for Luau: editor, tabs, themes, script folders, a signed updater, and a documented API surface.

Luau editor
A tabbed editor with syntax coloring, dirty and pinned tabs, Execute / Save / Open / Clear, and a status line for line, column, encoding, and language.
Tabs and workspaces
Keep several scripts open, switch with the tab strip, and use the side rail for explorer, folders, console, and settings without leaving the session.
Themes
Dark, Dracula, Catppuccin, Midnight, Nord, Tokyo, and GitHub. Each theme restyles the editor, chrome, and syntax together.
Script organization
scripts/, autoexec/, and bin/ live next to the executable when that folder is writable, otherwise under %LOCALAPPDATA%\Ionize. Auto-execute entries run on attach.
Signed updater
Ionize verifies Ed25519 update metadata, then checks the SHA-256 of the downloaded package before it is applied.
sUNC compatibility
Covers the full sUNC compatibility table, with every function in the tested standard set implemented or offered as an alias. Ships for Windows 10 and Windows 11 on x64.
Performance
The runtime does no background disk writing while you work. Diagnostics are off by default and opt in, keeping the editor responsive during heavy runs.
