  • Alexa supports the widest range of third-party smart home devices (over 140,000 skills), but heavily promotes Amazon’s own hardware (Ring, Eero).
  • Google Assistant works seamlessly with Nest products and Android phones, but has fewer compatible devices than Alexa; limited support for Matter protocol.
  • HomeKit offers the most secure, local-first control but requires “Works with Apple HomeKit” certification – significantly fewer devices, though expanding with Matter.
