Whats the fastest JSON unmarshaling package as of right now?

• easyjson

  10 4,491 1.7 Go

  Fast JSON serializer for golang.

  

  If you know the schema of the JSON ahead of time and you need to parse the whole object, I would recommend https://github.com/mailru/easyjson as that will likely give you the fastest result. This works in almost all use cases, and easy to use features such as string interning can save you a lot of time on memory allocation if you parse a lot of JSON objects with identical values.

• jsonparser

  15 5,472 0.0 Go

  One of the fastest alternative JSON parser for Go that does not require schema

  If you don't know the schema or you only need to access one or two fields in a much larger JSON object, I would recommend https://github.com/buger/jsonparser as it provides an easy API to access specific values without fully unmarshaling. This is an unusual use case though, 9 times out of 10 I would tend to use easyjson.

• go-json

  24 3,134 4.6 Go

  Fast JSON encoder/decoder compatible with encoding/json for Go

• simdjson-go

  6 1,822 4.0 Go

  Golang port of simdjson: parsing gigabytes of JSON per second
