Key Benefits

Why developers choose B58UUID over standard UUIDs

Compact Format

22 characters instead of 36. Reduces database storage, speeds up indexing, and makes URLs cleaner and more readable.

URL & API Friendly

No hyphens or special characters. Works seamlessly in REST APIs, GraphQL, and web routes without encoding.

Unambiguous Characters

Uses Bitcoin's Base58 alphabet. Eliminates confusing characters like 0/O and I/l for better readability.


                            Excludes: 0 O I l + / =

Zero Dependencies

All implementations use only standard libraries. No external dependencies means smaller bundle sizes and fewer security concerns.

Available Languages

Production-ready libraries with native package manager support
