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. (by bkille)

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.

A simple problem that isn't
Interesting article! If anyone is wondering more about bit iterators and algorithms, an well tuned implementation that supports BMI2 intrinsics is available and documented at bit (and its lecture), and bit-algorithms, along with its dynamic bitset from bitlib.

An optimized replacement of the infamous std::vector<🅱️ool>
I've seen too many scientific software packages write their own bitarray/bitvector classes, so I wrote a C++ library for bitvectors and related algorithms, BitLib, to hopefully alleviate that issue. BitLib has a number of advantages, namely:

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.

[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.
What are some alternatives?
When comparing BitLib and itsy_bitsy you can also consider the following projects:
