ULID 生成器
生成可排序的 ULID，并从任意现有 ULID 解码时间戳。
使用方法
Generate ULIDs
Set how many identifiers you need and copy the list. Each ULID is 26 characters of Crockford base32.
- Set the number of ULIDs.
- Copy the generated list.
- Paste a ULID below to decode its timestamp.
Why ULID?
ULIDs sort by creation time, unlike random UUIDs, and use a compact base32 alphabet that avoids ambiguous letters.
常见问题
What is inside a ULID?
The first 10 characters encode a 48-bit millisecond timestamp and the remaining 16 characters are random.
Are ULIDs unique?
The 80 random bits make collisions extremely unlikely, especially when combined with the timestamp.
