Wow so they have a desktop version again after many many years. That's huge.

I always liked their original UI - Photon[1][2]. Very lightweight and fast. Also a distinct and consistent style. I understand why they dropped it in favor of Qt and later Web technologies, but it's still a big loss.

I was expecting to see that, I ended up looking up some old LiteStep themes [1][2] for my fix

Yes while it makes sense to reuse stuff that is already being built, my heart sank when I saw the screenshot while expecting seeing the photon microgui which to me was the nicest skeuomorphic one.

Glad to see QNX still progressing. I worked there as an intern twice in Ottawa and they're pretty damn good. Great place to work imo. I met some of the kernel devs there. Had the priviledge of working with one and he taught and demoed some of the kernel features to me. They gave us interns a full summer course on kernels, C programming, OS and some hardware. Fun times.

Sometimes I wish I could do this for mid career sabbatical.

This is a major throwback to the QNX demo disk, which bundled a browser and desktop environment onto a single floppy disk!

sedatk 12/27/2025|

It was mind blowing at the time because Linux required at least 4-5 floppies to set up a text-only base system while QNX ran live from just a single 1.44MB.

fouc 12/27/2025|||

Photon microGUI was included in that, and it blew my mind that you could literally kill and restart Photon without disturbing any of the GUI apps that were still running.

They also mailed a manual along with the demo disk, and I was amazed that QNX had built-in network bonding, amongst lots of other neat features. At the the time I was using Slackware & the linux kernel version was still 1.x, I don't think bonding came to linux until 2.x?

viraptor 12/27/2025|||

When was that? You can still run from a single floppy https://github.com/Steve3184/floppinux and some form of that was available for ages.

fouc 12/27/2025|||

He meant with X & web browser and so on. The QNX disk had gui + browser and a few other gui apps.

sedatk 12/27/2025||

No I meant the base system. A system with X would take at least 20 floppies or so with Slackware 3. The whole setup was 80 floppies in total.

I’m sure it’s better now, it wasn’t so when QNX had come out.

sedatk 12/27/2025|||

Linux was like that in 1995 (Slackware 3.1 or so). I believe QNX live was introduced in 1997.

bregma 12/27/2025||

QNX was introduced in 1980.

Did I just wake up from a coma? QNX desktop? Wayland XFCE? What is going on here

harhargange 12/27/2025|

Seems like QNX was hiding in plain sight as a car os and a mission critical os for other devices.

IceWreck 12/27/2025|||

Blackberry OS 10 was also running QNX under the hook afaik.

bigyabai 12/27/2025||||

There are tons of proprietary RTOS/microkernel products on the market. It's not so much hiding as it is crowded-out.

jacquesm 12/27/2025||

And none of them can hold a candle to QnX. I've used a whole raft of them and QnX stands heads and shoulders above the competition. The consistency of the implementation is extremely impressive.

undefuser 12/27/2025||

I would like to hear more about your experiences. What makes QNX better than others?

jacquesm 12/27/2025||

Show me another OS that you can undress to the kernel, a console, a file system and a disk driver and then build it all up again without missing a beat.

The kernel processes are actual processes so each of the drivers is fully sandboxed, an error in one bit of code can not cause any other processes to be affected unless you explicitly declare that it should be so (shared memory, for instance) and of course you don't do that.

The reduction of scope alone is worth at least 30 IQ points.

Absolutely rock solid. I built some specialized network devices using QnX and those things ran for a decade+ after first installation. Not a single reboot.

IshKebab 12/27/2025|||

I think the market is moving to "mixed criticality" so you can use Linux for your entertainment system but then also use a proper RTOS for the car stuff all in the same SoC.

Bring back Photon. It was dang near perfect.

wowczarek 12/27/2025|

Photon was what I was hoping for before I clicked the link. One of my favourite GUIs, closely tied with CDE.

Photon or not, I hated the period where they sort of moved to canned BSP deployment only, where in 6.5 I could just develop on a live system. This is nice.

Animats 12/27/2025|||

Me too, although it's been a long time since Photon.

"This environment runs as a virtual machine, using QEMU on Ubuntu. To try the image, you'll need: Ubuntu 22.04 or 24.04." So it doesn't boot on bare metal?

Maybe they're trying to get away from needing Windows. The previous recommended development environment was cross-compilation from Windows.

The big news here is that they have a reasonable non-commercial license again.[1] The trouble is, QNX did that twice before, then took it away.[2] Big mistake. They lost their developer base. Support of open source tools on QNX stopped. As I once told a QNX sales rep, "Stop worrying about being pirated and worry about being ignored". They'll need to commit contractually to not yanking the non-commercial license to get much interest.

QNX should be licensed like Unreal Engine. If you ship enough products using it, it gets noticed and they contact you about payments, and if you're not shipping much product, Unreal doesn't care. This has created a big pool of Unreal developers, which, in turn, induces game studios to use Unreal. Unreal's threshold is US$1 million in sales.

Apparently they opened things up a bit last year, but nobody noticed.

Usefully, there is a QNX Board Support Package for the Raspberry PI, so you can target that. QNX would be good for IOT things on Raspberry PI machines, where you don't want the bloat and attack surface of a full Linux installation.

> QNX should be licensed like Unreal Engine.

That sounds quite a bit harder to enforce for an OS designed to run inside, often not internet-connected, devices.

justsomehnguy 12/27/2025||

If someone would decide to run QNX (or whatever) inside, often not internet-connected, devices then some IP enforcement wouldn't stop them anyway.

skrebbel 12/27/2025||

I mean it’s a realtime OS. It’s designed for that. So the pricing model has to work with that.

xvilka 12/27/2025|||

Right. These days it's better to invest into Redox OS[1] as a potential substitute for it (if work on real time capability). And with real time patches merged into Linux mainline[2] QNX doesn't stand much chance today too.

Correct me if I'm wrong but these and other Linux patches were always about soft real time and Linux never had hard real time capability because of its architecture.

xvilka 12/27/2025||

You are absolutely right. For most applications it's good enough though, unless regulatorily enforced.

jonhohle 12/27/2025||||

It’s really sad it wasn’t open sourced. In the early 2000s I was triple booting Windows 98, BeOS, and QNX. BeOS was my favorite, but QNX Neutrino was great as well.

In case you're not aware: CDE is still around, open source, and runs on modern unix-likes.

Oh I'm aware :) also this beauty from SGI is now around again:

There is also a FWWM[1] "skin" that doesn't require long time abandoned C code - NsCDE[2]. It still requires X server (just like CDE itself) which becomes rarity these days. They need to port it to Wayland eventually.

Eh, there's always https://gitlab.freedesktop.org/wayback/wayback for that.

rbanffy 12/27/2025||

I learned C on QNX (back then, it booted from a floppy on a PC/XT). It was a nice little Unix-like OS, with all the things you'd expect from a nice little Unix-like OS, plus a reputation of being rock-solid like nothing else.

I think it's a real shame Blackberry didn't manage to etch a third (or fourth - I also loved Palm's WebOS) niche for their QNX-based phones. Blackbberry 10 was an amazing mobile OS.

dcmatt 12/27/2025||

QNX is owned by Blackberry?! Blackberry still exists?

harhargange 12/27/2025||

Exactly. And there’s a huge community of the old Blackberry qnx device owners as well still trying to survive.

harhargange 12/27/2025|

As someone who still uses a QNX phone, the Blackberry Q10 as my second phone, I’m not just optimistic for the return of the cross-platform and secure os, I’m rooting for it. Especially for portable Linux handhelds. If Blackberry were to release a phone tomorrow, it would instantly be the most secure android phone. I still run some of my favourite android apps on my BB10os via the android translation layer.

Some comments mentioning QNX can run Swift code makes me think of it could also run iPhone apps.

While Blackberry exited the phone market, I’m surprised to know QNX is still the most popular os for cars. With 275 million devices running it atm.

f1shy 12/27/2025||

> QNX can run Swift code makes me think of it could also run iPhone apps.

Not at all. That is like saying because it can run C, it can run windows apps. To run iPhone apps you would need all the libraries and runtimes ported, including the whole GUI. Just not happening.

nicksbg 12/27/2025||

Tehnically, BB10 could run iOS apps at the beginning but, they disabled it before the release of PlayBook. Bad call.

gt0 12/27/2025|||

Swift is probably less than 1% of the what it takes to run iPhone apps, you can get Swift for Windows too, but it is nowhere near able to run iPhone apps. The problem is all the libraries an iPhone app expects to be available on the host OS, all the multimedia stuff and so on, those libraries on iPhone are large and advanced, and not available for porting to any OS outside of Apple.

PaulRobinson 12/27/2025||

Swift != SwiftUI. You need the latter to run modern iOS apps written in Swift.

It's great that Apple are pushing Swift out there a bit, but honestly if they want the World to catch fire with it, they need to give away the Crown Jewels and get SwiftUI out there as well.

Meanwhile, it's great that QNX is supporting modern languages. I can imagine having a bit of fun with this developer desktop and seeing how modern tooling plays nicely with it.

.NET is doing pretty good without all cross platform UI.
