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.

Bit-vector manipulations in standard C++
No benchmarks though. I saw itsy_bitsy, but other than find and sorting (neither of which I've ever needed), it's not really that much faster than std::bitset.

An optimized replacement of the infamous std::vector<🅱️ool>
Another library, to possibly compare against, is: itsy.bitsy.

What std::bitset could have been
Are patches you mentioned related to this library https://github.com/ThePhD/itsy_bitsy ?

[Suggestion] How to manage a (moderately) large number of bitvectors?
This might do what you need https://github.com/ThePhD/itsy_bitsy . I think it has bitwise ops like bitset but is a dynamic bit vector with decent perf.

New integer types I’d like to see
This is probably not what you're looking for because it might not be high performance. But in hardware synthesis/modeling, we use the so called "AC data types" and I just googled that and found it on Github.
https://github.com/hlslibs/ac_types
Arbitrary bit length, symmetrical and unsymmetrical, rounding and wraparound behaviour specifiable etc. etc.
What are some alternatives?
bitvec - A crate for managing memory bit by bit
go - The Go programming language
better_bitset - A better `std::bitset` that supports scanning for bits optimally
bitset2 - std::bitset with constexpr implementations plus additional features.
BitLib - Provides a bit-vector, an optimized replacement of the infamous std::vector<:b:ool>. In addition to the bit-vector, the library also provides implementations of STL algorithms tailored for bit-vectors.
BitArray - C bit array structs and methods
CRoaring - Roaring bitmaps in C (and C++), with SIMD (AVX2, AVX-512 and NEON) optimizations: used by Apache Doris, ClickHouse, and StarRocks
