The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.
IDLens decodes a UUID or ULID you select on any page.
Select the ID, right-click, and choose "Inspect ID with IDLens" — a small local popover shows the version, variant, and (for time-based IDs) the embedded timestamp.
- Supports UUID v1/v3/v4/v5/v6/v7/v8, Nil and Max UUIDs, and ULIDs
- Shows the embedded timestamp for v1/v6/v7 UUIDs and ULIDs
- 100% local: no network, no account, no tracking
- Minimal permissions: context menu + active tab only, no host permissions
Built for developers who work with IDs and want to know exactly what one is at a glance.
