Native Client (NaCl) is a sandboxing technology that allows you to run C and C++ code in web browsers. It's been used for various applications, including games and scientific simulations. The NaCl project itself has been somewhat deprecated in favor of WebAssembly (WASM) for running compiled languages in the browser, but it still has a place in certain niche applications.
