Amazon has been developing Vega OS for years, first testing it on Echo Show smart displays before bringing it to Fire TV. The first device to officially run this new operating system was the Fire TV Stick 4K Select, launched in October 2025. Following closely behind was the release of the Fire TV Stick HD in April 2026, which also operates on Vega OS. According to sources within Amazon, this transition aims to streamline performance and reduce hardware demands.

Documents show that one of the key features of Vega OS is its cloud-based architecture. “Vega OS is entirely run on the cloud,” sources say. This design choice allows for a more efficient use of resources; however, it has led to some notable limitations. For instance, unlike its predecessor, Vega OS does not support sideloading of apps—meaning users cannot install applications outside of those available through Amazon’s App Store.

Currently, Amazon’s App Store lists around 3,000 apps available for Vega OS devices, a stark contrast to the approximately 40,000 apps accessible on Android-based Fire TV sticks. This discrepancy raises questions about user experience and content availability moving forward. Yet, in an effort to mitigate these concerns, Amazon is reportedly streaming some Android-based Fire OS apps in the cloud on Vega OS devices to fill this app gap.

The performance enhancements associated with the new Fire TV Stick HD model are noteworthy; it is described as being over 30% slimmer and more than 30% faster than previous generations. Such improvements suggest that while app availability may be reduced, users can still expect a more responsive experience overall. However, it’s essential to note that Vega OS does not support Dolby Vision and Dolby Atmos audio formats—features that have become increasingly standard in modern streaming devices.

Amazon has made it clear that all future Fire TV Sticks will run on Vega. In light of this transition, many current users may find themselves reassessing their options as they weigh the benefits against the limitations imposed by this new operating system. “You cannot do that on the Select or forthcoming HD Fire TV Sticks—or any other future models,” an internal document confirmed regarding sideloading capabilities.

As this landscape continues to evolve, it remains to be seen how consumers will adapt to these changes in functionality and content availability. While some may appreciate the streamlined performance of Vega OS and its cloud-based advantages, others might find the reduced app ecosystem a point of contention.

Details remain unconfirmed about additional features or updates that might be introduced alongside future iterations of the Fire TV devices running on Vega OS. Nonetheless, it is clear that Amazon’s commitment to this new operating system will shape its strategy and offerings in the competitive streaming market for years to come.
