Uses crypto.randomUUID for browser-native random UUID generation.
Creates time-sortable identifiers with Crockford Base32 encoding.
Generates compact URL-friendly IDs using the nanoid package already used by the app.
Generate up to 500 IDs at once for seed files or test data.
Move generated lists into source files, tickets, or fixtures quickly.
Identifiers are generated in the browser with no account or backend call.
Use UUID v4 for broad compatibility, ULID when sortable IDs are useful, and Nano ID when compact URL-friendly identifiers are preferred.
No. The generated values stay in the current browser page until you copy, download, or regenerate them.
The UI allows up to 500 IDs per batch to keep the page responsive and the output manageable.
