Chromecast support depends on whether the app developer built it in
Chromecast is not blocked by Google or your TV — it only works with apps whose makers chose to add Chromecast support to their code. When you open Netflix or YouTube, those apps have built-in buttons and menus that talk to your Chromecast device. When you open a smaller streaming service or a website in your browser, that app or site may not have those buttons because the developer never added them.
Think of it like a car radio. Your car radio can pick up FM stations, but only if the radio station is actually broadcasting on FM. If a station only broadcasts on AM, your FM radio cannot receive it — not because the radio is broken, but because the station chose a different format. Chromecast works the same way: the app has to be built to send video to your TV, and many apps are not.
Key Takeaways
- Chromecast support is a feature that app developers must add themselves — Google does not force all apps to support it.
- Large streaming services like Netflix, Disney+, and YouTube support Chromecast because millions of users expect it.
- Smaller or newer streaming services often skip Chromecast support because building and testing it costs time and money.
- You can sometimes cast your entire screen or browser tab instead of using the app's built-in Chromecast button, though this uses more data and battery.
- Whether an app supports Chromecast is a business decision by the app maker, not a technical limitation of your device.
Why big streaming services have Chromecast but small ones do not
Netflix, Disney+, YouTube, Hulu, and HBO Max all support Chromecast because so many people use those apps on their phones and want to watch on a TV. When a developer knows millions of users will expect a feature, they build it. The cost of adding Chromecast support — hiring engineers, testing on different devices, fixing bugs — is worth it because it keeps customers happy.
A smaller streaming service with 50,000 users faces a different math. Adding Chromecast support means the same engineering cost, but spread across a much smaller user base. The developer has to choose: spend money on Chromecast, or spend it on video quality, customer service, or marketing. Many choose not to build Chromecast support because their users are fewer and their budget is tighter.
Some services also use DRM (digital rights management) — copy protection that limits how video can be sent to other devices. Chromecast support requires the app to work with DRM in a specific way, which adds complexity. A developer licensing content from studios may find that the studio's contract makes Chromecast support harder or more expensive to implement.
What happens when you try to cast from an unsupported app
When you open an app that does not support Chromecast, you will not see a cast button in the app itself. If you look for it in the menu or in the top corner where cast buttons usually live, it straightforward will not be there. This is not a glitch — the developer did not include the code to make that button work.
You may still see a cast button in your phone's quick settings menu (the panel you pull down from the top). That button casts your entire screen, not just the video. Screen casting works with almost any app, but it drains your phone battery much faster, uses more data, and sometimes shows your notifications or other apps on your TV while you are trying to watch. It is a workaround, not a solution.
How to check if an app supports Chromecast before you read it
On Google Play (Android), search for the app and scroll down to the "About this app" section. Look for a line that says "Requires Android" and the version number. Below that, you will sometimes see a note about Chromecast support, though not all developers list it there.
The most reliable way is to check the app's website or help section. Search "[app name] Chromecast support" and you will usually find a page that says whether it works. If the app's website does not mention Chromecast, it probably does not support it.
You can also open the app on your phone and look for a cast button — usually a rectangle with curved lines in the top right corner or in the menu. If the button is not there, the app does not support Chromecast.
Screen casting as a backup when the app does not support Chromecast
If an app does not have a built-in cast button, you can cast your entire phone screen to your Chromecast instead. Pull down your phone's quick settings menu (swipe down twice from the top), find the button labeled "Cast" or "Screen Cast," and tap it. Select your Chromecast device, and your phone screen will appear on your TV.
Screen casting works with any app, but it has real drawbacks. Your phone will get hot and drain battery much faster — expect to lose 20 to 30 percent of your battery per hour. Your data use will be higher. And if you get a text message or notification while casting, it will pop up on your TV for everyone to see. For a quick video, screen casting is fine. For watching a full movie or show, using an app with built-in Chromecast support is much better.
Why some websites do not support Chromecast even though they stream video
Websites that stream video — like a news site with embedded videos or a smaller streaming service with a web player — often do not support Chromecast because building web-based Chromecast support is different from building it into an app. A developer has to use a different set of tools and test on many different browsers and devices.
Some websites use video players made by third parties (like JW Player or Vimeo Player), and those players may or may not support Chromecast. The website owner does not always have control over that choice — they are using someone else's player and are stuck with whatever features it includes.
If you want to watch a website on your TV and it does not support Chromecast, screen casting your browser tab is your option. Open Chrome on your phone, go to the website, and use the cast button in Chrome's menu (three dots in the top right). This casts only the browser tab, not your whole screen, so notifications will not appear on your TV.
What you can do if your favorite service does not support Chromecast
Contact the service directly and ask for Chromecast support. If enough users request it, the developer may prioritize it. You can usually find a contact form or support email on the service's website.
Use screen casting as a temporary workaround, knowing it will drain your battery and use more data. If you watch the service regularly, this is not a long-term solution.
Check whether the service offers a Roku app, Fire TV app, or Apple TV app instead. Many smaller services support those platforms before they support Chromecast, so you might be able to watch on a different device.
Some services offer a web player on a computer or tablet that you can connect to your TV with an HDMI cable, though this is less convenient than casting.
Frequently Asked Questions
Can I force an app to work with Chromecast if it does not support it?
No. Chromecast support has to be built into the app by the developer. You cannot add it yourself. Screen casting your entire phone is your only option, and it uses more battery and data.
Does Chromecast work with web browsers?
Yes, but only if the website has Chromecast support built in. You can cast a Chrome browser tab from your phone to Chromecast, which works for many websites. Open Chrome, tap the three-dot menu, and select "Cast." Not all websites support this.
Why does Netflix have Chromecast but a smaller streaming service does not?
Netflix has millions of users who expect Chromecast, so the cost of building and maintaining it is worth it. Smaller services have fewer users and tighter budgets, so they prioritize other features. It is a business decision, not a technical one.
If I screen cast instead of using the app's cast button, will the video quality be worse?
Yes, usually. Screen casting compresses your entire phone display, which reduces video quality. Using an app's built-in cast button sends the video directly from the streaming service to your Chromecast, which is higher quality and uses less battery.
Will an app ever add Chromecast support if it does not have it now?
Sometimes. If a service grows and gets more users, they may add Chromecast support later. Smaller services may never add it if they do not have the budget or if their users prefer other platforms like Roku or Fire TV.
