Important question: Why would anyone develop a web application in C? Typically web applications lean heavily on garbage collection and memory safety, because their bottlenecks are very rarely CPU/memory issues. The ROI on manually managing memory just isn't there for a typical web application.
On the other hand memory management in web applications is quite easy.
Most of the stuff is only required for the lifetime of a request. Some stuff needs to be available the whole application life time.
You can do this with other languages (C# for example) as well. Memory is so cheap, though, that most companies should spend their money on increasing memory rather than on paying programmers to optimize memory usage.
Cheap for whom? American programmers with FAANG salaries, or an under-funded third world NGO?
