UUID Generator for Mac
A native Mac UUID generator. Grab a v4 UUID, or a hundred. Uppercase or lowercase, with or without hyphens. Copy and move on.
What it does
Bench's UUID generator produces version 4 (random) UUIDs using the operating system's cryptographically secure random number generator. You can generate a single UUID or a batch, choose uppercase or lowercase output, and copy the result with one click. For cases where you need to seed a database or populate a fixture file, the batch mode lets you produce a list of unique identifiers at once rather than clicking repeatedly. All generation happens locally. No request goes out.
Why use Bench's UUID generator
UUID generation is trivial but surprisingly hard to reach quickly. Terminal requires remembering
the right command (uuidgen on macOS, different on Linux). Web tools work but they're
another tab. Bench is one keystroke away, and the generator is there the moment you switch to it,
with nothing to configure.
- Native Mac app. SwiftUI, single window, instant launch.
- Offline. No network calls. Whatever you generate stays on your Mac.
- No tracking. Nothing you enter is logged, sent, or shared. Bench has no analytics and no third-party SDKs.
- Free download. Core tools are included. Bench Pro is an optional $14.99 one-time unlock for Pro tools, Smart Detection, and higher limits. No subscription.
Paste it. Bench picks the tool.
With Bench Pro, Smart Detection reads your clipboard locally and routes you to the UUID generator when it sees something like:
550e8400-e29b-41d4-a716-446655440000
In Bench Pro, detection runs entirely on your Mac as a rule-based heuristic. It checks for the 8-4-4-4-12 hex pattern that identifies a UUID. Nothing is uploaded.
