Nim is a statically typed compiled language that transpiles to C/C++/JavaScript. Web frameworks like Jester (micro-framework) and others let you build HTTP services in Nim. The language prioritizes readability, performance, and expressiveness. A single Nim program can be a full web server, no runtime overhead. Nim is niche. Few companies use it. Those that do cite: ultra-low latency (finance, gaming), small binary size (embedded, edge computing), raw speed comparable to C/Rust with simpler syntax.
