CPPBolt

It's a C++ compiler written in rust for web assembly that can compile and execute C++ code directly in the browser. It could be used by sites like leetcode, geeksforgeeks and others, so that they don't have to execute user's code on their server which saves lots of of money in server computing, also reduces existing server load, also no need to worry about if any malicious code is being executed on their server, and also give instant response when executing code. It is also very lightweight as of now raw wasm file size is 1.2mb. It is available on npm repository as well for any developer to start using it immediately(with proper easy to use instructions as well on readme).
