Format
Default: 550e8400-e29b-41d4-a716-446655440000
Turn off hyphens for 32 continuous hex characters.
Changing format options regenerates a new random set at the same count.

Tips
Fixtures: Generate 50–100 IDs, download, paste into migrations or tests.
Compact logs: Disable hyphens for shorter strings.
Clean a batch: Use Remove duplicates after a large run if you merged lists manually.
Keep in mind
UUID v4 (random) only — not time-based or name-based UUIDs.
App shortcuts
| Action | Shortcut |
|---|---|
| Search tools | ⌘ K |
| Close current tab | ⌘⌥E (Ctrl+Alt+E on Windows) |
Note: ⌘W closes the browser tab. ⌘⇧E focuses the Explorer in Cursor/VS Code. Use ⌘⌥E (Ctrl+Alt+E) to close the current tool tab (click inside the app first so the IDE does not steal the shortcut).
