This is a healthy thing to happen to the Linux browser ecosystem imho.

We talk a lot about browser diversity, but on Linux and Windows, it is a lie. You have firefox (gecko) and fifty flavors of chromium. Webkit on Linux has essentially been relegated to embedded devices or the GNOME epiphany browser, which I'll admit while is a noble effort, lags a bit in the stability and power-user features department. Big reason for that is that it lacks the commercial backing to keep up with the modern web standards rat race.

Kagi bringing orion to Linux changes the calculus. It introduces a third commercially incentivized, consumer-grade engine to the platform. Even if you never use orion, you want this to succeed because it forces WebKitGTK upstream to get better, which benefits the entire open source ecosystem.

The sticking point like always will be media playback (read: DRM/widevine). That is the graveyard where Linux browsers go to die. If Kagi can legally and technically solve the widevine integration on a non-standard Linux webkit build, they win. If not, it will be a secondary browser.

Been a Kagi subscriber for a while, and am supportive of a more diverse browser ecosystem. However, I won't be using this browser as long as it is closed source. Honestly, the arguments made by the founder (I believe he's the founder anyway. I may be wrong) in the related feedback thread kind of soured me a little bit on Kagi. The arguments were essentially:

1. It's a lot of work to maintain an open source project accepting community contributions. Absolutely true, but that's not what's being asked for. Providing a tarball under an open source license doesn't add any significant work. 2. No one has asked for the Kagi backends to be open sourced, so why is the browser different? Obviously because I run the browser on my machine. Your backend runs on your machine. 3. We need to protect our IP. Then release it under a copyleft license. Or if you absolutely must, release your proprietary bit under a non-open source license. 4. You don't need the source because we send 0 telemetry, which you can verify using a network proxy. That's hardly the only thing to be worried about with a binary blob. Even if you kept the code completely closed source, by just releasing a tarball with the source under a proprietary license, I can build my own binary from source and eliminate this threat.

It seems weird to run a closed-source browser on an open-source operating system when so many open alternatives exist—I certainly wouldn’t do it, and I’m a Kagi customer.

Does Kagi plan to open-source Orion on Linux?

I love Kagi. I understand the niche this fills. I even understand not open sourcing it yet.

But what I really miss is a self-hosted sync server. I don't want to use a browser without sync, but I also don't want to trust this data with any 3rd party other than myself.

It's one of the main reasons I'm using Firefox, since that is the the only browser that even vaguely supports this - albeit not well.

I think this is great. True native Linux-first power user browsers are nearly an entirely unserved niche. We've had them on macOS in various forms over the years (with OmniWeb being the original), but for a long time the only browsers built to integrate well with Linux desktops were minimal and light on features (like the WebKit version of GNOME Web/Epiphany).

It probably matters less to Linux users who do the minimal tiling WM thing, but as someone more drawn to traditional floating DEs it's always bothered me how alien the browsers one might actually want to use feel running in a GTK or Qt DE. Themes can help reduce the gap, but it never disappears — that last 10-20% always remains as an unavoidable side effect of how the big browsers are built, with it being particularly pronounced with Firefox and derivatives.

Of course a GTK based browser like Orion isn't going to feel the best under a Qt desktop like KDE, but GTK themed to match Plasma is a good deal closer than the bespoke UI found in e.g. Firefox or Chrome.

I've been a Kagi user for months now and was really looking forward to testing this. However, I cannot find the download link. The page does not really contain any information on an actual release.

EDIT: I found this in the docs:

> The alpha version of Orion for Linux is currently only available to [Orion+ supporters](../orion-plus/orion-plus.md) and can be downloaded from the [Billing Dashboard](https://kagi.com/settings/billing) under the Orion browser section.

So I still can't test this. Only for Orion+ supporters.

Orion has come an extremely long ways on iOS and macOS. I daily drove it for a couple months maybe a year and a half ago and it had a lot of little rough edges and was slightly broken on a number of websites.

I’ve picked it up again as my daily driver as of the new year and haven’t had a single issue yet. It even blocks ads in YouTube now - only Brave did that previously.

For me - Brave was the best browser product. It’s ad blocking is truly phenomenal and nearly every site “just works”. But I don’t love the ethics of Brave and certainly not its founder. So I am extremely excited to have Orion take over that niche of the browser space that I most care about.

Previously, my comments on Kagi were about one thing: counting queries felt like a chore, so I stayed away. I did give it a try mainly for the privacy angle. After that, I switched to Perplexity and was happy for a year, until the familiar VC backed pattern showed up: ads, even for paying users. This year I upgraded to Kagi Ultimate, and honestly, it feels like they’ve found the sweet spot. I hesitated at $25 at first, but the search experience plus the assistant (and the ability to pick the models I want) along with privacy won me over. I’m also familiar with Orion since I use it as the app for kagi experience for AI chat and search. It could use an update for better assistant experience. Keep up the good work, Kagi.

Wild that I can't use Kagi in Safari on iOS, where my search options are still locked down to three~four Apple-approved choices, of which at least one is just a multi-billion-dollar paid product placement.

(Yes, I know about the extension that hijacks your searches to redirect them to Kagi, but how is that an acceptable state of affairs?)

I hope they upstream their implementation of Web Extensions to WebKit.

I'm not interested in using a proprietary browser, and hope for a release under a free license at some point. But a free WebKit-based browser with Web Extensions could have interesting properties regarding battery life on mobile GNU workstations.

I first used Orion a couple years back and it was already pretty good back then. Super cool to see it coming to Linux!

I must +1 that no matter the platform (this criticism is not limited to Linux), the open source option is almost always my choice, especially for something as important as a browser. This is a big reason I don’t use Orion today, even though I have big issues with the other available browsers.

In case anyone is like me and has never heard of Orion, apparently it's a browser

There is some strange irony in this. Apple initially used the khtml code-base to build Safari but it quickly became impossible to back-port the changes from the Safari branch of khtml back into Konqueror. Now, 20 years later, someone has made an open source version of Safari.

If I'm a linux user who uses firefox currently, what's the value prop for this browser? I already get privacy and extensions, is it just for testing my app on webkit?

I'd like Psylo [1] to be available on other platforms like Linux and MacOS. Psylo puts each tab behind a VPN and give them their own cookie storage space. It feels like a dramatically more private tool than Orion.

I tried Orion in Dec 2025 and it crashed more frequently than I could handle. It and/or VPNs I was using worked poorly with websites that I want to keep a page open on for days at a time.

Is the Kagi Orion browser going for the "we hate loading and looking at ads, and maybe this is better than Chrome with uBlock Origin Lite" demographic?

(They don't seem to be going for the "serious, clueful privacy and Internet freedom" demographic, or they wouldn't be using Discord.)

Loved Orion but had to switch to Zen because they had an awful Picture-in-picture implementation and no mouse gesture support, both features I use heavily

Regardless, anything that works toward dethroning the 2 worst spyware distros in the world i.e. windows and osx I must support heavily

Congratulations on your release! Looks great. Runs great so far. I was able to log into HN just fine on Fedora.

What are your thoughts on upgrading gnome 48 to 49 as a dependency?

Orion is the only modern piece of software that has ever made my mac less stable as a system.

I don't know what they do, but it caused weird graphics glitches and kernel panics simply from running in the background.

It's a shame this isn't open source, since Linux users are disproportionately likely to scratch their own itches.

Regardless, great to see this come to Linux.

I tried the macos and ios versions of Orion yesterda and it was a great experience.

I've used Brave from the beginning but it has become bloated with web3-related stuff and has outdated UX (imo) on mobile.

Orion desktop is inspired by Safari, Arc in a best way. Ad-blocking and chrome/firefox extensions from the beginning, convenient vertical tabs, mature level of ui customization.

Glad it see on Linux too.

> Customize Everything Your Way Limitless customization that goes far beyond themes. Configure every detail to work exactly as you need.

That would be awesome!, but would be nice to have a list of things comprising "everything", Vivaldi is the best browser in this regard, and still they have plenty of gaps.

Orion is their browser built with Webkit.

This is great news. I just reinstalled orion yesterday. It was stuck crashing at every launch until I manually deleted the application files on macOS. That being said, I really like orion and kagi, but I agree with others that they should open-source orion.

A poorly made page. I don't know what an Orion is. I didn't learn it after skinning through the page. Now I don't even care.

I love what the kagi team is doing, and being some of the first innovators maybe since the ladybird(?) browser, even if it's using the same base of webkit, not being a fork of chrome or firefox. I wish they'd bring it to android, but it doesn't look like they're interested.

Oh just in time. Trying to switch from macOS to Linux soon.

I'm not a macOS user so I've got little experience with Safari. Is it actually a good browser? All I hear is how bad it is.

kudos for not doing yet another chrome clone.

Has Orion gotten significantly more stable in the last year? The last time I tried it, on iOS, it crashed a lot.

A closed source wrapper around a web view? I have to advise that no one install, never mind use, this closed source, proprietary blob. Especially not for anything confidential like banking, health, etc.

Shame it's GTK but oh well, still a welcome sight.

Curious why they would use webkit, I checked their FAQ, but couldn't find any answer.

It's rough, but I like it. Definitely an alpha, but wonderful to see them thrive.

Whats special about Orion? Why would I use it instead of FF or even Chromium?

Hmm. So from Mac to Linux?

Homebrew also initially had mac only support, later Linux. But it always felt as if Linux was a second-class citizen. Is that also the case for Orion?

Love to see it. I've been a paying Kagi member for three years (!), and for now I trust them more than Google, but I echo the other users' concerns that to switch to this long term I'd want it to be open source.

There is no legitimate reason for a web browser not to be open source.

I am not touching this with a 15m stick.

I use Zen and recommend people give it a shot. It's really good.

Just use Yandex browser and skip the middleman

No source code? That's pretty disappointing, and makes it DOA for most Linux users.

I like Kagi and pay for it. I've been impatiently waiting for Orion to come to Linux. But I won't run closed source.

This is a huge disappointment.

Nice. But I stopped using Orion on macOS when they stopped offering complete offline installers. They taut they are a zero-telemetry browser, as proof that they are privacy conscious about user data, and that was a good feature and overture. But then when they create technical avenues to (possibly) bypass that (like using online installers that can do all kind of data collection) it becomes harder to trust them as it follows the tried-and-tested path of other companies that have claimed to care about user privacy, to increase their user-base, and then betrayed their customer base by harvesting their personal data.

Lowkey I wish Perplexity would do this for Comet, idk why but I use the heck out of their browser on my Mac. I dont always use the "browser agent" stuff (lol!), and I dont use it for EVERYTHING, but you spend so much time looking things up, and sometimes its nice to just be able to highlight text on a page and go "yo ELI5 this for me pls I feel dumb" and it just does it.
