Utf8Json is a high-performance, zero-allocation JSON serializer for C# that reads and writes directly to UTF8 binary, targeting .NET, .NET Core, Unity, and Xamarin. The project is now archived, and users are directed to a community fork.
Use cases
- serialize objects to json in c#
- fastest json serializer for .net
- zero allocation json serialization
- json serializer for unity
- convert objects to utf8 json bytes
- high performance json parsing in c#
When to choose
- you need maximum JSON serialization throughput in .NET or Unity with minimal allocations
- you write directly to UTF8 streams or byte arrays and want to avoid encoding overhead
When to avoid
- you want an actively maintained library - the project is archived and a community fork is recommended
- you need UTF16 string-based serialization or broad modern .NET feature support
