If you have ever installed an app on a Fire Stick from outside Amazon’s Appstore, that option is going away on new models. In April 2026, Amazon confirmed that all future Fire TV Sticks will run Vega OS, its own operating system, instead of the Android-based Fire OS — and Vega OS devices do not support sideloading. If you are shopping for a streaming device, this changes what a Fire Stick actually is. Here is what is happening, which models are affected, and what your alternatives are. For the hardware side, see our SuperBox vs. Firestick hardware comparison, and if you are ready to look at an open Android box, our SuperBox model picker takes about a minute.
Vega OS is Amazon’s in-house operating system for Fire TV devices. Unlike Fire OS, it is not based on Android. That matters because Fire OS inherited Android’s ability to install apps from files — which is what made Fire Sticks popular with people who wanted more than the default app store. Vega OS is a locked-down platform limited to apps Amazon makes available in its Appstore, and reports indicate that selection is a smaller subset of what Fire OS offered.
As of mid-2026, two sticks run Vega OS, and Amazon says every future stick will follow:
Still on Android-based Fire OS for now: the Fire TV Stick 4K Plus, the Fire TV Stick 4K Max, the first-generation Fire TV Stick HD (2024), the Fire TV Cube, and smart TVs with Fire TV built in. A useful shortcut reported by Fire TV watchers: avoid models with “Select” in the name, and avoid “HD” models that list WiFi 6.
To check a stick you already own, open Settings, then My Fire TV, then About. A software version labeled “OS” starting with 1 is Vega OS; a version labeled “Fire OS” is the Android-based system.
On Fire OS models, yes, for now. On Vega OS models, no — tools like the Downloader app are not supported, and there is no setting to enable outside installs. The 4K Plus and 4K Max are expected to be the last Android-based Fire TV Sticks that allow sideloading. If you buy one of those today, you keep that ability, but you are buying the final version of a product line that is moving in the other direction.
Amazon is not alone. Roku has never allowed sideloading for everyday users — see Roku’s app restrictions and missing features. That leaves open Android devices as the main option for buyers who want to choose their own apps.
It depends on the model. Fire OS sticks are built on Android, but without Google Play or Google services, which is why some Android apps have never been available on them. Vega OS sticks are not Android at all. So even the “Android” Fire Sticks were a restricted version, and the new ones leave Android behind entirely.
A streaming device is only as useful as the apps it can run. On a closed platform, the manufacturer decides which apps you can use, and that list can shrink. On an open platform, you can install what you need: apps from Google Play, tools like file managers and browsers, and apps that developers distribute from their own websites. It also means your device is not stranded if an app you rely on is never approved for one company’s store.
Open does not mean careless. Stick to official stores and verified developer sources, and avoid unknown APK sites, which are a known source of malware. Our guide to whether Android TV boxes are legal and safe covers what responsible use looks like.
If you want an open platform, look at devices that run full Android with Google Play. Options range from Google’s own streamer to premium boxes; our SuperBox vs. Google TV comparison covers one of the most common matchups.
SuperBox is built for buyers who want that openness with more hardware headroom. Every model runs Android with both Google Play and the SuperBox App Store pre-installed, supports installing apps from verified developer sources, and includes 4GB of RAM, WiFi 6, and a built-in gigabit ethernet port. Our walkthrough on installing apps on SuperBox shows how each method works. The SuperBox S6 Max is available now with 64GB of storage, and the SuperBox S7 Pro is the entry point to the S7 generation. New to the category? Start with what an Android TV box can actually do.
If you already own a Fire TV Stick 4K Max or 4K Plus and it does what you need, nothing changes today. If you are buying new, check which operating system you are getting before you check out, because the name on the box no longer tells you. And if app freedom is the reason you liked Fire Sticks in the first place, it makes sense to move to a platform that is open by design rather than one that is closing. Our Roku vs. Fire Stick vs. SuperBox comparison lays out all three options side by side.
SuperBox TV Now sells streaming hardware only. What you watch depends on the apps you install and the services you choose to subscribe to.
Amazon’s announcement applies to new Fire TV Stick models. As of this writing, Amazon has not announced plans to convert existing Fire OS sticks such as the 4K Max to Vega OS. You can confirm what your device runs under Settings, My Fire TV, About.
No. Vega OS devices do not support sideloading, so Downloader and similar tools cannot install apps on them. Downloader still works on Fire OS models and on Android TV devices, where it is available from Google Play.
