I have created a webpage that displays all C++ features since C++20 in a simple, searchable table.
It is intended to serve as a quick reference for C++ developers, whether as support for cross-platform development or simply to track the current support status out of curiosity.
I created it as a simpler, more structured, and more up-to-date alternative to the cppreference compiler support site. Please note that the page intentionally does not list LWG and CWG papers. This might change as I am continually updating the site and trying out new ideas.
Questions, feedback and suggestions are appreciated, either here or in the form of GitHub issues.
Then there are whole industries where only C, C++ and Assembly matter, including standards, so it will take a while for new contenders to be taken seriously on such industries.
