Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

JSON vs FlatBuffers vs Protocol Buffers
According to the official website:
-
gRPC: The Bad Parts
> Protobuf is intentionally designed to NOT require any parsing at all.
As others have mentioned, this is simply not the case, and the VARINT encoding is a trivial counterexample.
It is this required decoding/parsing that (largely) distinguishes protobuf from Google's flatbuffers:

https://flatbuffers.dev/
Cap'n Proto (developed by Kenton Varda, the former Google engineer who, while at Google, re-wrote/refactored Google's protobuf to later open source it as the library we all know today) is another example of zero-copy (de)serialization.

Cap'n Proto 1.0
I don't work at Cloudflare but follow their work and occasionally work on performance sensitive projects.
If I had to guess, they looked at the landscape a bit like I do and regarded Cap'n Proto, flatbuffers, SBE, etc. as being in one category apart from other data formats like Avro, protobuf, and the like.
So once you're committed to record'ish shaped (rather than columnar like Parquet) data that has an upfront parse time of zero (nominally, there could be marshalling if you transmogrify the field values on read), the list gets pretty short.
https://capnproto.org/news/2014-06-17-capnproto-flatbuffers-... goes into some of the trade-offs here.
Cap'n Proto was originally made for https://sandstorm.io/. That work (which Kenton has presumably done at Cloudflare since he's been employed there) eventually turned into Cloudflare workers.

How do AAA studios make update-compatible save systems?
If json files are a concern because of space, you can always look into something like protobuffers or flatbuffers. But whatever you use, you should try to find a solution where you don't have to think about the actual serialization/deserialization of your objects, and can just concentrate on the data.

Or, as an alternative to protobuffers, there's also flatbuffers, which is lighter weight and needs less memory: https://google.github.io/flatbuffers/

Serializing struct with bit-fields
I have searched extensively, and have tried a few libraries from msgpack-c (C++), to YAS, and a few more not to name.

how about https://github.com/msgpack/msgpack-c/tree/c_master ?
What are some alternatives?
Protobuf - Protocol Buffers - Google's data interchange format
MessagePack - MessagePack serializer implementation for Java / msgpack.org[Java]
cereal - A C++11 library for serialization
Boost.Serialization - Boost.org serialization module
Cap'n Proto - Cap'n Proto serialization/RPC system - core tools and C++ library
