Over the past few weeks of testing and juggling both apps from these TP-Link brands, we can confidently say that you'll be happier sticking with one brand. Choose Tapo if you want better security camera controls and a more diverse selection of smart home devices like security sensors and robot vacuums—two device types absent from Kasa's lineup. Keep in mind that the brand doesn't sell a video doorbell yet. Choose Kasa if you want a video doorbell and a massive selection of smart plugs, smart outlets, smart light switches, and smart lighting options. Kasa's integrations with third-party smart home platforms like Alexa and Google feel much more developed than Tapo's. Kasa has better integration with Samsung SmartThings, one of our favorite ways to manage smart home gear. We'd like to say that each brand targets customers with different budgets in the same way that Amazon's Blink and Ring cameras do, but there's only the slightest price difference in Kasa's favor. We're still determining TP-Link's endgame for having two nearly identical smart home brands. Previously, we would have said that Tapo catered to European customers, but it's hard to say now that we have both brands in the U.S. Plus, Kasa isn’t struggling—it's consistently a top seller on Amazon. Tapo's starting to catch up in the same categories as well. There's no way to say how long TP-Link can run both brands separately, but having cross-compatibility between them would undoubtedly smooth things out for everyone.
