C++ REST SDK
The C++ REST SDK is a Microsoft project for cloud-based client-server communication in native code using a modern asynchronous C++ API design. This project aims to help C++ developers connect to and interact with services.

catch2 has become fairly bloated. doctest takes all of the best parts of catch2 without all the bloat and the end result is a test framework that is literally over 10x faster than catch2. It's also like 90% compatible with catch2 so porting your tests to it is pretty easy.
Especially if you have a build process that always runs your unit tests, it's nice to have a very fast test/compile/debug loop.

CLI11
CLI11 is a command line parser for C++11 and beyond that provides a rich feature set with a simple and intuitive interface.
> I switched from C++ to C about 7 years ago and never looked back
I'm definitely considering the same, and you're right - it's not C++ itself that appeals to me at all, it's the libraries. I'm not sure what C libraries I'd use for collections (instead of the STL and Abseil [0]), or in lieu of CLI11 [1] or Dear ImGui [2].

For example, here's the documentation[2] for a thread safe heterogeneous thread-aware memory and header[3] for the underlying thread safe pool.
It uses a mutex, but at a glance only when it needs to consult the fallback allocator (which could involve a system call). If you knew that the fallback allocator were a pre-allocated arena, maybe you could do with atomics only. The free list is already lock-free, and so too could be the block list.
