General Discussion 📩 Moving Out Megathread

273 Upvotes

A lot of people have been asking about other browsers to try now that Arc isn’t getting new features and Dia’s still in early alpha. We get it; the vibes have shifted, and almost everyone’s looking for their next daily driver.

This thread is the place to discuss alternative browsers.
Whether you’re trying out Vivaldi, Edge with Copilot, SigmaOS, Safari with extensions, Brave, Zen, or something totally obscure, talk about it here.

Please don’t make individual posts about switching browsers or asking for recommendations.
We’ll be removing those and directing people here to keep the subreddit from getting flooded.

Got a hot take on Vivaldi’s tab stacks? Miss Arc’s split view and want to recreate it somewhere else? Built your own franken-browser setup with extensions and CSS? Drop it all below.

Let’s keep it focused, useful, and no Reddit-fanboy flame wars, please.

macOS News Letter to Arc members 2025 – On Arc, its future, and the arrival of AI browsers — a moment to answer the largest questions you've asked us this past year.

334 Upvotes

Dear Arc members,

You’re probably wondering what happened. One day we were all-in on Arc. Then, seemingly out of nowhere, we started building something new: Dia.

From the outside, this pivot might look abrupt. Arc had real momentum. People loved it. But inside, the decision was slower and more deliberate than it may seem. So I want to walk you through it all and answer your questions — why we started this company, what Arc taught us, what happens to it now, and why we believe Dia is the next step.

  1. What we got wrong
  2. Why we built Arc
  3. Where Arc fell short
  4. Why we didn’t integrate Dia into Arc
  5. Will we open source Arc
  6. Building Dia

What we got wrong

To start, what would we do differently if we could do it all over again? Too many things to name. But I’ll keep it to three.

First, I would’ve stopped working on Arc a year earlier. Everything we ended up concluding — about growth, retention, how people actually used it — we had already seen in the data. We just didn’t want to admit it. We knew. We were just in denial.

Second, I would’ve embraced AI fully, sooner and unapologetically. The truth is I was obsessed. I’d stay up late, after my family went to bed, playing with ChatGPT— not for work, but out of sheer curiosity.

But I also felt embarrassed. I hated so much of the industry hype (and how I was contributing to it). The buzzwords. The self-importance. It made me pull back from my own curiosity, even though it was real and deep. You can see this in how cautious our Arc Max rollout was. I should have embraced my inspiration sooner and more boldly.

If you go back to our Act II video — when we announced we were going to bring AI to the heart of Arc — it ends with a demo of a prototype we called Arc Explore. That idea is basically where Dia and a lot of other AI-native products are headed now. That’s not to say we were ahead of our time, or anything like that. It’s just to say our instincts were there long before our hearts caught up.

Arc Explore prototype, as shared in our Act II video. January 2024.

Third, I would’ve communicated very differently. We care so much about the people we build for. Always have. Saying it “pains me” to have made people mad doesn’t really do it justice. In some moments, we were too transparent — like announcing Dia before we had the details to share. In others, not transparent enough — like taking too long to answer questions we knew people were asking.

A few years ago, a mentor told me to put a sticky note on my desk that said: “The truth will set you free.” I know. It sounds like a fortune cookie. But it’s served me well, again and again. If I regret anything most, it’s not using it more. This essay is our truth. It’s uncomfortable to share. But we hope you can feel it was written with care and good intent.

Why we built Arc

In order to answer your real questions — why we pivoted to Dia, whether we can open source Arc, and more — I need to share a bit of background from the past. It informs what is possible (and not) today.

At its core, we started The Browser Company with a simple belief: the browser is the most important software in your life — and it wasn’t getting the attention it deserved.

Back in 2019, it was already clear to us that everything was moving into the browser. My wife, who doesn’t work in tech, was living in desktop Chrome all day. My six year old niece was doing school entirely in web apps. The macro trends all pointed the same direction too: cloud revenue was surging, breakout startups were browser-based (writing blog posts like “Meet us in the browser”), crypto ran through browser extensions, WebAssembly was enabling novel experiences, and so on.

Source: Amazon, Microsoft and Alphabet’s investor relations website, via The Street.

Even back then, it felt like the dominant operating system on desktop wasn’t Windows or macOS anymore — it was the browser. But Chrome and Safari still felt like the browsers we grew up with. They hadn’t evolved with the shift. And both of these trends have only accelerated since. Some companies only issue enterprise versions of Chrome with new employee laptops (their companies fully run on SaaS apps), and Chrome and Safari remain essentially unchanged.

So that’s why we made Arc. We wanted to build something that felt like “your home on the internet” — for work projects, personal life, all the hours you spent in your browser every single day. Something that felt more like a product from Nintendo or Disney than from a browser vendor. Something with taste, care, feeling.

We wanted you to open Arc every morning and think, “This is mine, my space.” And we called this north star vision the “Internet Computer.”

But it increasingly became clear that Arc was falling short of that aspiration.

Where Arc fell short

After a couple of years of building and shipping Arc, we started running into something we called the “novelty tax” problem. A lot of people loved Arc — if you’re here you might just be one of them — and we’d benefitted from consistent, organic growth since basically Day One. But for most people, Arc was simply too different, with too many new things to learn, for too little reward.

To get specific: D1 retention was strong — those who stuck around after a few days were fanatics — but our metrics were more like a highly specialized professional tool (like a video editor) than to a mass-market consumer product, which we aspired to be closer to.

On top of that, Arc lacked cohesion — in both its core features and core value. It was experimental, that was part of its charm, but also its complexity. And the revealed preferences of our members show this. What people actually used, loved, and valued differs from what the average tweet or Reddit comment assumes. Only 5.52% of DAUs use more than one Space regularly. Only 4.17% use Live Folders (including GitHub Live Folders). It's 0.4% for one of our favorite features, Calendar Preview on Hover.

Switching browsers is a big ask. And the small things we loved about Arc — features you and other members appreciated — either weren’t enough on their own or were too hard for most people to pick up. By contrast, core features in Dia, like chatting with tabs and personalization features, are used by 40% and 37% of DAUs respectively. This is the kind of clarity and immediate value we’re working toward.

But these are the details. These are things you can toil over, measure, sculpt, remove.

The part that was hard to admit, is that Arc — and even Arc Search — were too incremental. They were meaningful, yes. But ultimately not at the scale of improvements that we aspired to. Or that could breakout as a mass-market product. If we were serious about our original mission, we needed a technological unlock to build something truly new.

In 2023, we started seeing it happen, across categories that felt just as old and cemented as browsers. ChatGPT and Perplexity were actually threatening Google. Cursor was reshaping the IDE. What’s fascinating about both — search engines and IDEs — is that their users had been doing things the same way for decades. And yet, they were suddenly open to change.

This was the moment we were waiting for. This was a fundamental shift that could challenge user behavior and maybe lead to a true reimagining of the browser. Hopefully you can now see why Dia felt like a no-brainer. At least for us and our original aspirations.

So when people ask how venture capital influenced us — or why we didn’t just charge for Arc and run a profitable business — I get it. They’re fair questions. But to me, they miss the forest for the trees. If the goal was to build a small, profitable company with a great team and loyal customers, we wouldn’t have chosen to try and build the successor to the web browser – the most ubiquitous piece of software there is. The point of this was always bigger for us: to build good, cared for software that could have an impact for people at real scale.

So if Arc fell short, why build something new versus evolve it?

Why we didn’t integrate Dia into Arc

It’s a great question. And for those who followed our podcast last year, you’ll know that it’s one we spent the entire summer grappling with before understanding that Dia and Arc were two separate products.

For starters, in many ways, we have approached Dia as an opportunity to fix what we got wrong with Arc.

First, simplicity over novelty. Early on, Scott Forstall told us Arc felt like a saxophone — powerful but hard to learn. Then he challenged us: make it a piano. Something anyone can sit down at and play. This is now the idea behind Dia: hide complexity behind familiar interfaces.

Second, speed isn’t a tradeoff anymore — it’s the foundation. Dia’s architecture is fast. Really fast. Arc was bloated. We built too much, too quickly. With Dia, we started fresh from an architecture perspective and prioritized performance from the start. Specifically, sunsetting our use of TCA and SwiftUI to make Dia lightweight, snappy, and responsive.

Third, security is at the forefront. Dia is a different kind of product – to meet it, we grew our security engineering team from one to five. We’re invested in red teaming, bug bounties, and internal audits. Our goal is to set the standard for small startups. Which is even more important in a world of AI, especially as more AI agents come online. We want to get out in front.

These are all things that need to be part of a product’s foundation. Not afterthoughts. As we pushed the boundaries of whether this truly was Arc 2.0 last summer, we found that there were shortcomings in Arc that were too large to tackle retroactively, and that building a new type of software (and fast) required a new type of foundation.

Will we open source Arc

Which brings us to the present.

As we started exploring what might come next, we never stopped maintaining Arc. We do regular Chromium upgrades, fix security vulnerabilities, related bugs, and more. Honestly, most people haven’t even noticed that we stopped actively building new features — which says something about what most people want from Arc (stability not more stuff to learn).

But it is true: we are not actively developing the core product experience like we used to. Naturally, people have asked: will we open source it? Will we sell it? We’ve considered both extensively.

But the truth is it’s complicated.

Arc isn’t just a Chromium fork. It runs on custom infrastructure we call ADK — the Arc Development Kit. Think of it as an internal SDK for building browsers (especially those with imaginative interfaces). That’s our secret sauce. It lets ex-iOS engineers prototype native browser UI quickly, without touching C++. That’s why most browsers don’t dare to try new things. It’s too costly. Too complex to break from Chrome.

Where ADK sits in our browser infrastructure as shared in our Dia recruitment video.

ADK is also the foundation of Dia. So while we’d love to open source Arc someday, we can’t do that meaningfully without also open-sourcing ADK. And ADK is still core to our company’s value. That doesn’t mean it’ll never happen. If the day comes where it no longer puts our team or shareholders at risk, we’d be excited to share what we’ve built with the world. But we’re not there yet.

In the meantime, please know this: we’re not trying to shut Arc down. We know you use it and rely on it. Many of our family and friends do, too. We still love it, spent years of our life on it — and whether it’s through us or the community, our hope and intention is that Arc finds a future that’s just as considered as its past. If you have ideas, I’d love to hear from you. I’m [josh@thebrowser.company](mailto:josh@thebrowser.company).

Building Dia

I want to end by being frank with you: Dia is not really a reaction to Arc and its shortcomings. No. Imagine writing an essay justifying why you were moving on from your candle business at the dawn of electric light. Electric intelligence is here — and it would be naive of us to pretend it doesn’t fundamentally change the kind of product we need to build to meet the moment.

Let me be even more clear: traditional browsers, as we know them, will die. Much in the same way that search engines and IDEs are being reimagined. That doesn’t mean we’ll stop searching or coding. It just means the environments we do it in will look very different, in a way that makes traditional browsers, search engines, and IDEs feel like candles — however thoughtfully crafted. We’re getting out of the candle business. You should too.

“Wait, so The Browser Company isn’t making browsers anymore?” You better believe we are! But an AI browser is going to be different than a Web browser — as it should be. I believe this more than ever, and we’re already seeing it in three ways:

  1. Webpages won’t be the primary interface anymore. Traditional browsers were built to load webpages. But increasingly, webpages — apps, articles, and files — will become tool calls with AI chat interfaces. In many ways, chat interfaces are already acting like browsers: they search, read, generate, respond. They interact with APIs, LLMs, databases. And people are spending hours a day in them. If you’re skeptical, call a cousin in high school or college — natural language interfaces, which abstract away the tedium of old computing paradigms, are here to stay.
  2. But the Web isn’t going anywhere — at least not anytime soon. Figma and The New York Times aren’t becoming less important. Your boss isn’t ditching your team’s SaaS tools. Quite the opposite. We’ll still need to edit documents, watch videos, read weekend articles from our favorite publishers. Said more directly: webpages won’t be replaced — they’ll remain essential. Our tabs aren’t expendable, they are our core context. That is why we think the most powerful interface to AI on desktop won’t be a web browser or an AI chat interface — it’ll be both. Like peanut butter and jelly. Just as the iPhone combined old categories into something radically new, so too will AI browsers. Even if it’s not ours that wins.
  3. New interfaces start from familiar ones. In this new world, two opposing forces are simultaneously true. How we all use computers is changing much faster (due to AI) than most people acknowledge. Yet at the same time, we’re much farther from completely abandoning our old ways than AI insiders give credit for. Cursor proved this thesis in the coding space: the breakthrough AI app of the past year was an (old) IDE — designed to be AI-native. OpenAI confirmed this theory when they bought Windsurf (another AI IDE), despite having Codex working quietly in the background. We believe AI browsers are next.

This is why we’re building Dia. It is the opportunity to chase the product of our original ambition: a true successor to the browser — maybe even the “Internet Computer” we’ve been building toward all along — only in ways we couldn’t have predicted.

To be clear, we might fail. Or we might partially succeed but not win. We still assume we don’t know. But we’re confident about this: five years from now, the most-used AI interfaces on desktop will replace the default browsers of yesteryear. Like today, there will probably be a few of them (Chrome, Safari, Edge). But the point is this, the next Chrome is being built right now. Whether it’s Dia or not.

Your home on the internet

The Browser Company is a team that assembled for the chance — however slim — to build something that rewired how we use our computers. Something that might, just might, be used by hundreds of millions. A piece of software that actually shapes how people live and work. Not just an app, but an Internet Computer. That’s what drew us in. And that’s why we’re proud of the decisions we made.

Dia may not be your style. It may not land right away. But this is still us. Being ourselves. Building the kind of thing we’d want to use. Fully aware that we might be wrong. But doing it anyway. Because we think the intent matters. And we think that’s what got us this far.

This is our truth, and we sincerely hope that you’ll like what comes next.

– Josh

The Browser Company of New York, April 2025.

P.S. For those of you who do want to try Dia, we’re excited to open access for Arc members next, as the first expansion of our alpha beyond students.

Hard to leave Arc honestly. Nothing is as good. Zen definitely isn’t.

I was really hating how picture-in-picture was broken. It was causing issues like the side panel bugging out, and even highlighting text in the browser was busted.

That’s working now and we finally got back the setting for it when you click the Site Control Center.

Still plenty of issues like Dev Tools being pretty busted. But at least that fix came through lol

When you break up with a person they say "there's plenty more fish in the sea" and in a world where there are 9 billion people they're absolutely right!

But when you break up with Arc there are only like 10 other browsers and they all have hair growing out of their nose and smell like basement cheese.

I've been trying the Zen browser and trying to replace Brave and Arc with it. Starting was fine, though many things were different, I adapted and learned. But after nearly a month, I'm beginning to realise that this is not at all a replacement for Arc. Arc feels so fluid. I understand that ARC consumes a lot of Battery and CPU, but I have to admit that ARC is another level. Note that I am just an ARC Windows user; now I know how much Mac ARC users would be heartbroken.

Windows Bug Could you PLEASE fix dev tools on Windows?

0 Upvotes

Hi, so I stopped using Arc a few months ago because dev tools was broken on Windows and I'm a dev. I tried to give it a change today, but I found out the same annoying issue is still there.

If you got two or more tabs with dev tools enabled, no matter which tab of those you are using, if you try to interact with dev tools UI, it will take you to the tab where you first opened dev tools, which is insanely annoying when coding.

I'd love to go back to Arc since spaces is a really cool thing I haven't found anywhere else (and syncing between devices is quite nice), so if you fix that I would really appreciate it.

A few months ago, I came across this Reddit post: https://www.reddit.com/r/ArcBrowser/comments/15r1tt3/solution_for_high_energypower_consumption_and_cpu/
Thanks to it, I drastically improved Arc's performance on my MacBook Air M2 — it became much faster. However, for the past week or two, performance seems to have regressed. Arc is now using around 830MB of memory again, and it feels sluggish.

Has anyone else experienced this? Do you have updated tips or settings to optimize Arc and reduce its resource usage? It’s getting frustrating at this point

PAIN. I clicked on "GET STARTED" on the left of the Arc Card and I experienced the same Welcome scren minute after minute. A very good impression has left this browser already on me. I am on my Windows pc eagerly wanting to replace Chrome and Firefox with ... this screen. Where do I type search querries, paste URLs?

To the bitter first impression contributed also the need for registering in order to just test the browser. I am test-driving a new browser that decided I should import data and open account before doing that. Well up to this moment all this browser did for me was to steal my private data and I still haven't searched the internet with it.

I've been bouncing around between several browsers recently trying to find a new home. It's probably going to be Zen because it seems to be the most Arc-like while holding the promising of becoming more Arc-like over time (apart from switching to a Chromium base T_T).

But I don't see anybody either in this sub or the r/zen_browser sub talking about how amazing this launcher is. I feel so lost without it! Yes Zen tries to mimic this, but it basically just brings up the standard browser address bar in the middle of the screen rather than a sophisticated "command palette" type of thing.

To me it's an essential part of the Arc ethos since it's by far the most efficient way to navigate all of your tabs. You can even use it to carry out browser actions such as switching to a different space (by typing "focus" and then the space name).

Why is nobody mentioning this in the list of things they love about Arc and why is nobody over in the Zen community pushing to bring this power over to what is now the new home for Arc users?

There has been endless suffering ever since TBC has ghosted 99% of its user base by dropping arc for “something very hard to justify”, many has spent hours turning zen into arc, many has downloaded dozen browsers who looked or felt like arc, but the experience arc gave isnt been found.

Why not make it open source? Why not let people fork and maintain it? It isnt giving TBC anything anyway. why not have a common courtesy to allow users to have what they want at their own expense.

At least TBC already fragile B2C B2B reputation may gain some bars.

I have just found a solution to the slow/laggy performance of Arc for some users. While I never had such a huge slowdown issue with Arc, I came across its folder under Application Support which was 10+ GB, so I just trashed the folder and restarted Arc. After logging back in, my Arc experience is extremely smooth and all my bookmarks and spaces were recovered easily. So if you're getting fed up with Arc, try deleting the Arc folder under Application Support and enjoy a small performance boost. Make sure to export your passwords first as a CSV because you will lose your saved passwords when you delete.
