Everyday objects run on Linux far more often than most people realize. When someone hears “Linux,” they usually picture a programmer typing commands into a black terminal window. In reality, Linux is quietly running inside things you touch every single day — most of which have no visible operating system at all.
Linux isn’t just a desktop alternative to Windows or macOS. It’s a free, open-source operating system that companies can modify and build into almost anything with a chip inside it. That flexibility is exactly why it ended up everywhere.
Here are 10 everyday objects that run on Linux, whether you knew it or not.
1. Your Android Phone
This is the biggest one, and also the most overlooked. Android, the operating system on the majority of smartphones worldwide, is built directly on top of the Linux kernel. Every time someone unlocks an Android phone, they’re using Linux.
Google took the Linux kernel — the core part of the operating system that talks to the hardware — and built the entire Android experience on top of it. So the phone in your pocket has more in common with a Linux server than most people would guess.
2. Your Wi-Fi Router
That plain little box blinking in the corner of your living room is almost certainly running Linux. Most consumer routers, from budget models to high-end mesh systems, use a stripped-down Linux distribution to manage your network traffic.
Why routers use Linux
- It’s free, which keeps manufacturing costs down
- It’s small enough to run on cheap, low-power chips
- It’s easy to customize for networking tasks like firewalls and traffic routing
Enthusiasts even install custom Linux-based firmware, like OpenWrt or DD-WRT, on top of their router’s stock software to unlock extra features.
3. Your Smart TV
Flip on a modern smart TV and there’s a good chance Linux is running the interface behind the scenes. LG’s webOS and Samsung’s Tizen, two of the most common smart TV platforms, are both built on Linux foundations.
That means the app store, the streaming apps, and the menu system on your TV are all sitting on top of the same open-source kernel that powers servers and smartphones.
4. Your Car’s Infotainment System
Modern cars are basically computers on wheels, and a lot of that computing runs on Linux. Tesla’s infotainment system is built on a Linux-based platform, and a group of major automakers — including Toyota, Honda, Mazda, and Subaru — use a shared platform called Automotive Grade Linux for their in-car displays and controls.
What Linux handles in your car
- The touchscreen infotainment display
- Navigation and media playback
- Some driver-assistance and dashboard systems
The engine control itself usually runs on separate, specialized systems, but the screen you tap and swipe while parked at a red light is very likely running Linux underneath.
5. Your Steam Deck
Valve’s handheld gaming device runs SteamOS, which is built on a Linux distribution called Arch Linux. This was a genuinely big deal in the gaming world, since it proved a Linux-based system could run thousands of Windows-made PC games through compatibility tools, without needing Windows at all.
The Steam Deck’s success also pushed other handheld gaming device makers to look more seriously at Linux-based operating systems instead of defaulting to Windows.
6. Your Amazon Kindle
E-readers need to sip battery power for weeks at a time, and Linux is well suited for that kind of lightweight, efficient use. Amazon’s Kindle e-readers run on a customized Linux operating system, tuned specifically for e-ink displays and long battery life.
It’s a good example of Linux doing exactly what it’s good at: running quietly in the background of a device that just needs to work, without draining resources.
7. ATMs and Self-Checkout Kiosks
Plenty of ATMs and retail self-checkout machines have shifted to Linux-based operating systems over the past decade, moving away from older Windows versions that eventually lost official support and security updates.
Banks and retailers like Linux for the same reasons everyone else does: it’s stable, it’s secure when properly maintained, and it doesn’t require paying licensing fees on thousands of machines.
8. The New York Stock Exchange
The trading systems behind the New York Stock Exchange run on Linux. Financial markets need extremely fast, extremely reliable computing, since even tiny delays can affect trades worth enormous amounts of money.
Linux’s reputation for stability and low-latency performance is exactly why major exchanges moved their core trading infrastructure onto it, away from older proprietary systems.
9. The International Space Station
Even outside the atmosphere, Linux is on the job. The laptops used by astronauts aboard the International Space Station were migrated to Linux from Windows several years ago, largely for reliability and security reasons in an environment where a crashed computer isn’t a minor inconvenience.
Linux’s open-source nature also makes it easier for engineers to inspect, modify, and harden the code for the extreme demands of spaceflight.
10. NASA’s Mars Helicopter
Linux didn’t just make it into orbit — it made it to another planet. NASA’s Ingenuity helicopter, which flew alongside the Perseverance rover on Mars, ran an open-source Linux-based flight system on a repurposed smartphone processor.
Ingenuity flew 72 flights on Mars between 2021 and 2024 before rotor damage grounded it for good, making it the first aircraft to achieve powered, controlled flight on another planet. It remains one of the most quietly remarkable Linux success stories ever, proving open-source software could handle a mission tens of millions of miles from the nearest tech support line.
Why Linux Ended Up Everywhere
There’s a simple reason Linux shows up in so many unrelated places: it’s free to use, free to modify, and doesn’t lock companies into licensing fees for every device they build. A router manufacturer and a car company have very different needs, but both can start from the same open-source foundation and shape it into whatever they need.
- It’s free and open-source, so there are no licensing costs per device
- It’s modular, so manufacturers only include the parts they actually need
- It’s stable, which matters for devices that need to run for years without a reboot
- It’s secure when maintained, since the code is open for anyone to review and patch
That combination is hard to beat, especially for devices that just need to work quietly in the background for years at a time.
Honorable Mentions
The list above only scratches the surface. A few more everyday and not-so-everyday examples worth knowing about:
- Smart refrigerators and washing machines — Several major appliance brands run Linux-based platforms to power their touchscreen controls and app connectivity.
- Airport check-in kiosks and departure boards — Many airports run Linux on the backend systems that print boarding passes and update flight information.
- Traffic light controllers — A number of city traffic management systems run on Linux-based industrial computers.
- Drones — Many consumer and commercial drones, including popular models used for photography and mapping, run Linux-based flight controllers.
- Set-top boxes and streaming devices — Some cable boxes and streaming hardware use Linux under a custom interface layer.
None of these devices advertise it on the box, which is really the whole story of Linux in one sentence. It doesn’t need credit to keep working.
Frequently Asked Questions
Does my Android phone actually count as running Linux?
Yes. Android is built directly on top of the Linux kernel, even though the interface looks nothing like a traditional Linux desktop. Under the hood, it’s Linux managing the hardware.
Why do companies choose Linux instead of Windows for devices like routers and ATMs?
Linux is free to license, lightweight enough to run on cheap hardware, and easy to customize for a specific purpose. Windows licensing costs and resource requirements make it less practical for small embedded devices.
Is the Linux running on my TV or router the same as the Linux on a computer?
It’s the same core kernel, but heavily customized and stripped down. Manufacturers remove anything they don’t need and build a specific interface on top, so it usually looks nothing like a typical Linux desktop.
Does NASA still use Linux on Mars?
Ingenuity’s Linux-based flight system flew successfully from 2021 until early 2024, when rotor damage ended its mission. Future Mars aircraft concepts are expected to build on the same open-source approach.
Can I install Linux on my own devices at home?
Yes, on plenty of them. Routers can often run custom Linux firmware, and Linux distributions for desktop and laptop computers are free to download and install, though modifying a manufactured device like a smart TV or Kindle can void your warranty.
Editor’s Opinion
what i find funny is people think linux “lost” to windows becuase almost nobody has it on there home pc, but thats missing the whole point lol. its literally running your phone, your router, your tv, and a helicopter on MARS. it just doesnt announce itself, it just quietly works in the background doing its job with no logo poping up. kinda respect that honestly, linux is like the guy at the party nobody notices but the whole party wouldnt happen without him.
