功能亮點

UUID v4

Uses crypto.randomUUID for browser-native random UUID generation.

ULID

Creates time-sortable identifiers with Crockford Base32 encoding.

Nano ID

Generates compact URL-friendly IDs using the nanoid package already used by the app.

Batch Output

Generate up to 500 IDs at once for seed files or test data.

Copy or Download

Move generated lists into source files, tickets, or fixtures quickly.

No Server State

Identifiers are generated in the browser with no account or backend call.

常見問題

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.
