Why crosspec exists
Configurators, not buying guides.
Every page is an interactive tool that filters real products against real constraints. No "best X of 2026" listicles, no AI-generated copy padding.
Sources cited per claim.
When a product page says "works with HomeKit via Matter" you can click through to the registry entry with the ingest date. The data layer is the moat.
One revenue model, disclosed.
Amazon Associates affiliate links. That's it. No ads, no signup, no tracking cookies, no email capture. Direct buy works fine if you'd rather skip the kickback.
Open data.
The KBs are on GitHub under MIT for code and CC-BY-4.0 for data. Cite + redistribute. PRs that fix wrong mappings are welcome.
