Show HN: Lytok v3.0.1 – A high-density data protocol (JSON alternative) (github.com)

Hi HN,

I've been developing a data serialization format designed to be significantly lighter than JSON by eliminating repetitive key verbosity and optimizing the overall structure. Today, I'm open-sourcing the JavaScript SDK (lytok-js).

In our latest benchmarks using the WASM engine, Lytok achieves:

A 64.77% payload reduction.

50.19% faster network and parse speeds.

49.51% LLM token savings when feeding complex structures to AI models.

The core idea is that the structure is distilled through a definition map (which you can test in the Lab). This allows the engine to handle the heavy lifting so that thin clients and high-traffic networks aren't saturated with redundant data.

I'd love to hear your thoughts, architectural critiques, or optimization suggestions.
