Script Launcher
Manage and run Python scripts from multiple root folders.
Script Launcher lets you organize and run Python scripts directly from the 3D Viewport sidebar — keeping your workflow entirely inside Blender.
⚠️WARNING
This add-on runs Python scripts directly inside Blender. Always review a script's contents before executing it, and never run scripts from sources you do not trust.
Features
- Multiple root folders — Register as many script directories as you need. Personal scripts, project tools, and shared libraries can all coexist in a single panel.
- Folder tree view — Scripts are displayed in a collapsible tree that mirrors your directory structure. Expand only what you need, collapse the rest.
- Run scripts instantly — Execute any
.pyfile with one click. - Open in Blender's Text Editor — Load a script into Blender's built-in editor for quick review or editing. No context-switching required.
- Open in file manager — Jump to the script's location on disk in one click.
- Persistent UI state — Expand/collapse states survive list refreshes and file reloads.
- Search scripts — Real-time filtering by name. Type in the input field next to the 🔍 icon, click × to undo.

What's New
1.2.1 June 11th, 2026
- Execute scripts with
compile()/exec()so__name__is"__main__"andif __name__ == "__main__":blocks run as expected - Suppress bytecode cache writes during execution to keep script folders free of
__pycache__ - Exclude existing
__pycache__folders from the panel tree - Tidy preferences UI (General section, "Category (N-Panel)" label)
This is awesome! Thank you! It would be great if it didn't create the __ pycache __ folder when you run a script or if needed, it could be hidden from the panel.
