simdjson seems to be the gold standard in terms of JSON-parsing performance. It's always being updated with state-of-the-art algorithms for parsing, makes excellent use of intrinsics, and supports both arm and x86_64. It's also in use by many different organizations and has extensive testing via fuzzing etc. . I don't know what the performance needs are for JSON parsing here at Spotify, but if there's any desire for more speed, simdjson would be a great choice. It could be used as an SAX tokenizer, or simply forked to have spotify-json's high-level API built on top of it.
