A fast C# implementation of ULID (Universally Unique Lexicographically Sortable Identifier) for .NET and Unity. It generates sortable random IDs faster than Guid.NewGuid with zero-allocation parsing and serialization.
Use cases
- generate sortable unique ids in .net
- fast ulid generation for c#
- replace guid with sortable identifiers
- generate ulids in unity
- high-performance id parsing without allocations
- lexicographically sortable random ids for database keys
When to choose
- you need time-sortable unique identifiers in .NET or Unity
- performance matters and you want faster-than-Guid generation with zero allocations
- you want Guid interop and a familiar API
When to avoid
- you only need standard GUIDs with no sorting requirement
- you are not on a .NET or Unity platform
