Most CLI tools are either fast but painful to write (C), or easy but slow (Python/Node).

Zig's comptime generics change the game. You get:

• Zero-cost abstractions — generic argument parsers, pipeline composers, and dispatch tables that resolve entirely at compile time

• No runtime overhead — your CLI starts in microseconds, not milliseconds

• Type-safe everything — catch errors before your code ever runs

At CompTime CLI Lab, I teach you how to build production CLI tools using these techniques. 12 hands-on lessons. Real code. Real tools you can ship.

If you're a systems programmer, Nim developer, or backend engineer tired of compromising between performance and developer experience — this is for you.
