No, you cannot cast directly from Chromecast to a Roku device

Chromecast and Roku are separate casting systems that do not work together. A Chromecast device receives streams from your phone, tablet, or computer. A Roku device has its own built-in casting system called Roku Cast, which works only with Roku-compatible apps and devices. If you try to cast from a Chromecast-enabled app to a Roku TV or player, the Roku will not appear in your list of available devices.

The two systems use different underlying technology and do not recognize each other on your home network. This is a hardware and software limitation, not something you can work around with settings or apps. If you own both devices, they will operate independently in your home.

Key Takeaways

  • Chromecast and Roku are incompatible casting systems that cannot communicate with each other.
  • Some apps like YouTube, Netflix, and Spotify support both Chromecast and Roku Cast, so you can cast the same content to either device separately.
  • If you want to use one casting system throughout your home, you need to choose either all Chromecast devices or all Roku devices.
  • Roku TVs have Roku Cast built in, while Chromecast requires a separate device plugged into an HDMI port.

Which apps work with both systems

Many popular streaming apps support both Chromecast and Roku Cast, even though the devices themselves cannot talk to each other. YouTube, Netflix, Disney+, Hulu, Spotify, and Pandora all have cast buttons that work on both platforms. This means you can cast the same show or song to a Chromecast device one day and a Roku device the next—you just cannot cast to both at the same time.

The cast button in these apps will only show you devices that match the app's supported systems. If you open Netflix on your phone and tap the cast icon, you will see your Roku TV or Roku player listed, but not a Chromecast device connected to a different TV. The app is doing the filtering based on what it detects on your network.

Less common apps may support only one system or neither. Before buying a device, check whether the apps you use most often have a cast button for that platform. The app's help page or settings menu usually lists which devices it supports.

Roku Cast versus Chromecast: how they differ

Roku Cast is built into most modern Roku TVs and Roku streaming players. It works with phones, tablets, and computers running Android, iOS, Windows, or macOS. When you cast to a Roku device, the content streams directly from your device to the Roku over your home network.

Chromecast is a separate device you plug into an HDMI port on any TV. It works with phones, tablets, computers, and other devices that have the Chromecast app or built-in casting support. Chromecast devices are made by Google and come in different models, including Chromecast with Google TV, which also functions as a streaming player.

The key difference is that Roku is a complete ecosystem—the TV or player itself handles casting—while Chromecast is an add-on device. Neither system recognizes the other, so your phone will not show a Roku device when you are casting from a Chromecast app, and vice versa.

What to do if you have both devices at home

If you own both a Chromecast and a Roku device, they will work fine in the same home as long as they are on the same Wi-Fi network. They straightforward will not interact with each other. You will need to choose which device to cast to based on which TV or screen it is connected to.

Some people use Chromecast in one room and Roku in another. Others prefer to standardize on one system to avoid confusion. If you are buying a new device and already own one system, matching it will make casting simpler—you will see only one set of devices in your apps, and you will not have to remember which casting system works with which TV.

If you are replacing an older TV or player, check whether the new model supports the casting system you already use. Many newer Roku TVs come with Roku Cast built in, while Chromecast devices are sold separately and work with any TV that has an HDMI port.

Alternatives if you want unified casting

If you want all your devices to use the same casting system, you have a few paths. You can buy Chromecast devices for every TV in your home—they are relatively inexpensive and work with any television. Alternatively, you can buy Roku TVs or Roku players for each room, which have casting built in and do not require a separate device.

Google also makes Google TV, which is built into some TVs and streaming devices and supports Chromecast natively. If you see a TV or player labeled "with Google TV," it will work with Chromecast casting. This is different from a standard Roku TV, which uses Roku's system instead.

Before buying, confirm that the device you are considering supports the casting system you want. Check the product page or manual for the phrase "Chromecast built-in" or "Roku Cast" to know which system it uses.

Troubleshooting when a device does not appear

If you are trying to cast and your Roku or Chromecast device does not show up in your app, the most common cause is that the device is not on the same Wi-Fi network as your phone or computer. Both your casting device and the source device (phone, tablet, or computer) must be connected to the same network for casting to work.

Restart both devices: unplug the Roku or Chromecast device for 30 seconds, then plug it back in. At the same time, restart your phone or computer. Once both are back online and connected to the same Wi-Fi, open the app again and look for the cast icon. It should now appear in the list of available devices.

If the device still does not appear, check that the app you are using actually supports that casting system. Not every app has a cast button, and some apps support only one platform. The app's settings or help section will tell you whether casting is available.

Frequently Asked Questions

Can I use a Chromecast remote to control a Roku TV?

No. Chromecast and Roku remotes are not compatible with each other's devices. A Chromecast remote controls only Chromecast devices, and a Roku remote controls only Roku devices. If you have both in your home, you will need both remotes.

Will a Roku TV work with Google Home or Alexa?

Yes, Roku TVs work with both Google Home and Amazon Alexa for voice control and casting. You can say "Hey Google, cast Netflix to my Roku TV" or use Alexa in the same way. The TV must be on the same Wi-Fi network and set up in the Google Home or Alexa app first.

Can I cast from a Chromecast device to a Roku?

No. Chromecast devices are designed to receive casts from phones and computers, not to send them to other devices. A Chromecast cannot cast to a Roku, and a Roku cannot cast to a Chromecast.

What if my TV has both Roku and Google TV built in?

Some newer TVs have both systems available, though this is rare. Check your TV's settings or manual to see which casting system is active. You can usually choose which one to use, but you cannot use both at the same time. Pick the one that matches the devices and apps you use most.

Is one casting system better than the other?

Both systems work well and support most major streaming apps. Chromecast is simpler if you already use Google services and Android devices. Roku is a good choice if you want a complete streaming TV experience without buying a separate device. The best choice depends on which devices you already own and which apps matter most to you.
