They picked up a lot of cues from Arc - sidebar tabs, pinned vs generic tabs, global bookmarks, spaces...

Firefox is "copying" from Zen, and I think that's good. I do like Zen, but I wouldn't mind having all the features in Firefox (and imho some of the UI lately in Zen is... weird)

For my personal usage I find the deep nesting of TST to get in the way more than it helps and so the simpler model of Arc/Zen where nesting only happens intentionally is nice.

Hmm what's Sidebery missing?

> Hmm what's Sidebery missing?
The extensions themselves aren't lacking, but they suffer from being extensions and not part of the browser proper, which makes for occasional weird interactions and glitches and the "seams" between extension and host becoming tangible from time to time. Things just work better when the browser "knows" about the tabs being vertical and having deeper organization than is possible with horizontal tab bars, or is even designed around vertical tabs being the only option (like Arc/Zen).

You can add all the features, but you can't make them work well together (or look nice in some cases - which does matter!)

Sidebery can do the 80% of TST that matters, with a better UI and UX and saner defaults. Also it has a feature to save and restore all tabs, with the whole tree structure preserved (even though I think it should be its own extension)
Only problem is that I suspect that Sidebery has severe memory leaks (not entirely sure it's the culprit though)

- The distinction between pinned (soft-bookmarked) tabs and other tabs is very useful for me organizing things at work. (I didn't like when Arc added a setting to auto-delete other tabs X days after creating, though)
- Multiple "spaces" on the tab bar combined with global bookmarks at the top mean I can have a space for planning work and one for implementation work, and from both of those I have an easy link to Jira to search up tickets without needing to hop back and forth.

I’m pretty sure I saw more Arc videos posted after Dia than before. None of the people seemed to be aware that the browser they were pushing was effectively end of life.

Arc existed long before Dia, and had AI shoved into it when LLMs exploded, then the company decided to go all-in on an AI browser, Dia, and orphaned Arc...

Something is super, super fucked up with valuation of companies and the profiteering of late stage capitalism for stuff like that to be able to happen.
No wonder lots of people are saying the world feels worse than ever, everything's expensive and it seems in many ways we've regressed rather than "made things better for our children".

The closest thing right now is Orion. It does the vertical tabs and the page modification in the same way. Webkit based.
It's made by the Kagi guys who I really agree with - bootstrapped and not VC backed. A sustainable business. And charging for a service instead of making your customers the product. That's real ethics to me.
Their browser is not open source, though, which is a major blow. But it would seem most browsers are not truly now, if you look into it.
The reason I switched was because it is the only browser that, on iOS, allows chrome/firefox plugins. I'm not even sure how they're doing this as I thought banning non-crippled plugins was part of the 'device is not mine' policy from Apple. But it's there. All my plugins. Including the ones I made myself.
I realize this sounds like an Ad. Not affiliated. I just think they're doing good stuff.

You can get Claude Pro for $20/month and if you hook it into a browser, I'm not sure what you'd be missing out on from those listed perks.
I mean I get the benefit of a prepackaged experience but not at 5x the cost.

/EDIT: I looked into this by... well, asking Dia:
> That fits what I described. You aren't on a plan because you haven't had to pick one yet. People who were using Dia before paid plans launched on August 17 kept the AI features for free, with nothing to choose and no card on file. Dia says it will email those users at least 30 days before that changes.
>
> So nothing's wrong. It just isn't permanently free either. It's free for now because you joined early. When the notice email comes, you'll have about a month to decide:
So I'm grandfathered "for now", but the Daily brief and AI features are so low value to me, I just assumed they're free for everyone because of how little they do. I never use the built-in AI in Dia and get annoyed when a query that I wanted to go to a search engine gets answered by the assistant instead.

It's picked up all the most important parts of Arc's design while leaving behind the bits that were questionable (such as TBC's decision to not have bookmarks) and at this point it's pretty solid.
I had been continuing to use Arc for the odd site that insists on something Chromium-based (usually without good reason) since it's the only chromeclone that feels somewhat at home on macOS and hasn't succumb to an ugly generic flat look. It'll be missed.

For a while Arc was my main, but I switched to Orion when it was announced that Arc was going on maintenance mode. Since then I've waffled between Orion and Safari.

The only reason I can figure out is that they decided the technical foundations were just wrong, which would be surprising because they put an astonishing amount of work into building some very specific technical foundations for Arc.
Now that Chrome has native vertical tabs I'm back on Chrome, but I do miss Arc's tab tidying and organisation.

I’m still pulling for Atlassian to do Interesting Things with the app. AI can be part of it but I think there’s a ton of opportunity for a browser for the enterprise / organizations and atlassian is well positioned to do that, AI or no. Things like: - shared company file Management accessible directly in app - cross saas–app workflows enabled at the browser level, managed centrally by the org — slack, zoom, screen sharing/recording and other collab tools natively baked into the app
So many people spend all their work day flipping between different apps and docs in the browser and there’s sooo much more we (as humanity) could do to improve that experience. The browser is a natural site for it and I hope someone gives it a shot.

After a year to cool off, I gave Dia a shot. Despite wanting to hate it, I like the browser a lot. You can turn off the shit AI features, and it's a well designed and thoughtful UX.
As much as Josh is a tool, this is genuinely a great product and the team at TBC has executed really well.

But that's why I personally liked it, it was for a power user. Having multiple profiles, and a clean working environment, a lot of small but smart really thought out features. It felt like a actual revolutionary product.
In Dia there is a constant menu bar, for instance to make it easier for users. But it spoils the whole clean experience of Arc.
Dia seems to be just for mainstream, I can understand giving the focus to Dia, but removing Arc seems to be foolish. Especially when so many people are still using it.
Dia is focused more on AI tools, and seems to be more distracting for me, the focus seems to be to sell us a subscription, it feels quite different from the straightforward feature rich, power user browsers, which was Arc.

If you do, and you regularly tile windows, you know that vertical tabs are terrible because if you have 2 browser windows and tile them side-by-side, suddenly 40% of your screen is wasted showing tabs on 2 windows.
I really don't want to learn an entirely different set of multitasking shortcuts just for my browser. I know how to multitask with my browser already, the same way I multitask with everything else, and none of the solutions seem more convenient.

Most browsers try to port the vertical tabs or the split view and proudly say "look, we did it, you can now switch from Arc" but none get this tab concept right, except for Zen which regrettably uses Firefox/Gecko as its base.

Obviously more interesting if I'd thought to screenshot prior to going to bed but you can have multiple tabs in a 'stream' and they can be terminal or web tabs. The relay (which I'm pentesting in the screenshot) transports the AI chats to a paired phone where they're adapted to have a common UI across the Claude / Codex / Oh My Pi that I use. You can obviously see the Arc lineage to the ideas here.
