vsergeev/zigradio

zigradio is a niche project that demonstrates how to implement SDR components (like buffers, decimation, and signal chains) in the Zig programming language. While Zig is an excellent choice for low-level DSP due to its memory safety and performance, this specific project has very low defensive value (49 stars, 1 fork, and zero recent activity). It functions more as a personal experiment or a code reference for Zig developers interested in radio than as a viable competitor to established giants like GNURadio, Pothos, or even more modern Rust-based alternatives like future-sdr. The lack of community engagement and the age of the project (over 3 years old with no velocity) suggest it has been largely abandoned or surpassed by other efforts. There is no moat here; the code is a straightforward implementation of known DSP algorithms. Frontier labs have zero interest in this space, and platform risk is non-existent as this is local hardware-interfacing software. It is easily displaced by any active SDR project with better hardware driver support (e.g., SoapySDR integrations).
