What trends in C++
C++ is where performance-critical software lives: game engines and emulators, graphics and audio, databases, robotics, and the inference engines that run language and vision models on local hardware. A project can be on this list even if most of its users call it from Python, because the language is assigned by where most of the code is.
Expect a build, not a command
Trying a C++ project usually means installing a compiler and dependencies and running a build system, or downloading a release binary. Those steps do not fit in one line, and this site does not pretend they do: there is no command box unless the README has a real install line. Check the release page of the repository for prebuilt downloads.
For all languages together, see today’s list, this week or this month.
