Not all ID generators are created equal. Random integers collide. Sequential integers leak data. UUIDs, ULIDs, and Nanoids are designed for distributed systems where uniqueness is non-negotiable.
Open ID Generator →Statistically guaranteed uniqueness across distributed systems. The default choice for database primary keys and resource identifiers.
Lexicographically sortable and unique. Embeds a timestamp prefix so records sort by creation time. Database-friendly.
Compact, URL-safe identifiers. Shorter than UUIDs with configurable alphabet. Perfect for user-facing IDs in URLs.
