Neat tool, but I noticed it shows that modules are mostly supported when they are at best partially supported. You can double check with the famous "Are we modules yet?" website.

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.
