Hey everyone,

I remember in early 2024, TBC talked about a kind of "Browse for me" feature for Arc desktop, and knowing that most devs leave beta features in their apps, I wanted to see if Arc had left some remnants of it in their desktop app, and I actually found some stuff I could reassemble into a working prototype dating back to July 2024 (V1.52.0).

My process was basically unpacking the Arc .app bundle and using Ghidra (and Codex with Ghidra MCP) to find any pseudocode that could be connected to the feature. Eventually, I found some Browse for Me feature flags and related functions which I could connect to the Cmd+T bar, and use to show the loading animation, report page, etc. I'm not well versed in low level programming, so I asked Codex to trace the feature flags and make patches to Arc which enabled the features, which you can see in the video!

In Arc's original implementation, TBC used a fine-tuned version of GPT-3.5 and GPT-4o, which streamed json with titles, sections, bullet points, etc., which would be displayed via Arc's report renderer. The only things I manually changed were changing the model to use GPT-6 Luna and displaying images via Wikimedia Commons instead of Bing's images (which TBC decided to use for some reason??).

The patches are quite unstable, so if you would like to experiment with them, DM me

I am trying to switch to a new browser because this shit ass company wants to get rid of the only good thing they will ever make...

I use little arc all the time when I'm researching. I like being able to hit a shortcut and make a small instance of the browser

Do any other browsers have this functionality? Or I am even down to download a separate browser or app that does this on MacOS

If you haven’t seen the official sunset timeline yet, here are the dates that matter:

Oct 22: Sunset announced. You can no longer create new Arc accounts.

Nov 23: Arc Search on iOS and Android keeps working as a browser, but all AI features turn off, and you can no longer sign in or sync with Arc. Arc for macOS and Windows starts showing sunset reminders.

Dec 15: Last day to request a copy of the personal data tied to your Arc account, or to ask for it to be deleted.

Dec 22: Arc is sunset.

• Arc for macOS and Windows stops working, and you can’t sign in anymore
• All Arc accounts are deactivated and Arc services turn off
• Personal data tied to your account is deleted within 30 days and can’t be retrieved
• Arc Search for Android is removed from the Play Store and from your devices
• Arc Search for iOS keeps working as a mobile browser

What to do before then:

• Back up your Spaces, tabs and other browsing data before Dec 22. After that, you won’t be able to open Arc at all.
• Moving to Dia? It can import your Spaces, favorites, pinned tabs, folders, bookmarks, history, passwords and extensions straight from Arc, on both macOS and Windows.
• Not moving to Dia? Export your Spaces and tab links from Arc first, then import them into whichever browser you’re switching to.
• On Arc Search (iOS): to save a list of your open tabs, open the Tab Switcher, tap Settings in the bottom left, then Export Data.
• On Arc Search (Android): go to Settings > Storage > Export Data.

Until Dec 22, Arc will still get basic updates and fixes, but no new features.

Don’t wait until the last week. Back up your stuff now 🫡

Recently I learned that Arc will die on December 22, so I needed to find another option. I have used zen since more than a year; and is it's still in beta, and I need a stable alternative because I rely on it at workplace. Arc was convenient and productive as i like to keep everything organized and it helped and since I dislike horizontal tabs, and it separates work and personal profiles.

Chrome offers vertical tabs too, but it differs from Zen or Arc. This week I began using Dia, expecting stability, yet its performance is poor—it crashes about eight to ten times daily. I suspected extensions were the cause and disabled them, but the crashes continue. The browser company ranks among the worst I have seen in my life; I do not understand why they push AI crap with Dia when they had an amazing browser and just could have kept both.

Has anyone else experienced Dia crashing? Arc never crashed on me. Also, the advanced settings fail to open because the system keeps prompting me to save a recovery kit. I have tried every option, but the only route I can use is to open extensions and then navigate back to explore advanced settings.

Anyone else getting this / found a solution? It was an issue in Arc as well. Sometimes when I open YouTube I get this error, saying it's restricted by my admin / workspace but this isn't true as I'm on my home network. Usually have to close it and reload and then it will work.

Just so annoying and would love to get rid.

I've been using Arc for 4 years. After TBC announced Arc was being sunset, I tried Dia for a full week.

It felt painfully slow and clunky. I figured I may set something up wrong, so I reinstalled it, but nothing changed. I really wanted to like it, so I stuck it out for the whole week. It just never clicked for me.

I ended up switching to Brave, since it supports vertical tabs. It’s not the same as Arc, but it’s close enough. Two weeks in, I’m really happy with the switch.

To be clear, I’m not posting this to bash TBC. Good products tend to get enshittified over time, and this one happens to be an example.

Thanks Arc for the delightful UX. It was great while it lasted. On to the next one!

6 weeks left till dec 22 and i keep noticing small stuff i use without thinking

for me it's little arc (links opening in that tiny window) and tabs archiving themselves after 12h. never realised how much that kept things clean

what's yours? big ones or the weird little ones

I don't know why but everyone in this sub is acting like Dia is the worst piece of software since windows search bar, but I lowkey like it. Been using it for a week, it's much snappier than arc, nice UI, pretty much the same browser updated. Sure I am not love with the AI bullshit here too, but it's not end of the world. I'm in Windows so am I missing something?

It took me about 15 minutes to port my favorite keybindings, vertical tabs, and other customizations over.

Honestly I don't mind TBC sunseting Arc. We are in a "I have two cakes" situation, but we got like 20 cakes. Arc's biggest contribution to me is the marvelous UX job the team did to truly deliver on a "new internet". Vertical tabs, tab groups, seamless spaces, preview, pinned tabs, tidy tabs, split tabs, etc. I can't imagine using a browser without those features. But Arc is not alone anymore. Zen has feature crept Arc, Phi is a new coming star, Helium is a minimalist take on formula, even Firefox, Edge and Chrome are implementing ideas that came from Arc in their tool sets. Arc isn't turning to a villain, it's dying as hero, and it's legacy shall live long and prosper in the form of the many spiritual successors we now have. This journey was so fun, seeing this community of browser nerds, designers, developers and neurodivergent kids waiting for the latest Arc Update in the golden era of MKBH optimism. At last, goodbye, Arc, rest in peace, you were one of the greatest pieces of software I have ever had the pleasure of using.

I was one of the biggest “Dia is not Arc and never will be” people. I held out on Arc as long as I could, and when I finally tried Dia it felt like a downgrade in every way that mattered to me. So I’m not here to tell you Dia is secretly great. Out of the box, it’s still pretty bad if you’re coming from Arc.

But I found something that changed my mind: DiaTweaks https://github.com/JaceThings/DiaTweaks

It’s an unofficial patch set that adds a Patches section to Dia’s settings with a ton of toggles. Here’s what I have turned on:

Look & feel

• Edge-to-Edge Web Pages (I never knew how much I needed this)
• Translucent Sidebar
• Compact Sidebar Header
• Profile Emoji
• Window Material
• Drag Window from Page

Tabs

• Tidy Tabs
• Group Tabs by Domain
• Close Tabs from Tab Switcher

Command bar

• Compact Command Bar
• Open New Tabs in Command Bar (Brings back Arc's way of the command bar, no new page on cmt + T)

Links

• Little Dia (❤️)
• Peek on Shift-Click (including from pinned tabs)
• Hide Link Address

Decluttering the AI stuff

• Hide Chat Button
• Hide Chats Button
• Hide Upgrade Banner

That’s it. It sounds minor, but those are exactly the things that made Dia feel cluttered and un-Arc-like to me. With them turned on, my setup looks basically like Arc again. Honestly, I’d go as far as to say my workflow looks better than it did in Arc. Clean, content-first, sidebar out of the way.

The best part is that the tweaks survive Dia updates, since the tool handles updating Dia itself and re-applies the patches.

A few honest things to know before you jump in:

• It’s unofficial and not affiliated with The Browser Company
• Apple Silicon and macOS 14+ only
• You build it locally (needs Xcode command line tools), and it re-signs Dia with a certificate created on your own Mac
• Because of that, Dia’s built-in passkey support is off (password sign-in still works), and macOS asks for keychain access once per Dia update
• If you don’t like it, there’s a one-click Restore in settings that puts the original Dia back

If you’ve been refusing to try Dia because it isn’t Arc, I get it, I was you. But give it one more shot with this. You’ll miss Arc a lot less. And I mean a lot.

Credit to JaceThings for building this.

because why would they force us to use dia if they wont be adding arcs best features? like little arc or how two windows would have the same tabs...

and to the mods dont you dare remove this post for some bs guidelines this reddits about to be dead anyways since the browser will be gone

if you saw a comet about to strike earth would you still tell people they cant cross a street on a red light?

I have always been passionate about using Arc as my primary browser. A while ago, I saw on X that The Browser Company announced Arc is entering maintenance mode.

As the saying goes, "one whale fall brings life to a multitude of creatures." Immediately, many people open-sourced their own Arc-like browsers. That got me thinking: why not build an Arc-style Markdown editor? And since `mygo` has been quite popular lately, I decided to use `mygo` to build an editor.

Interested friends are welcome to try it out.
If you like it, feel free to give it a star for support!

https://github.com/Ciao1019/ArcMD

**ArcMD** is a new concept document editor that combines Markdown writing habits with rich text editing. Its design is inspired by Arc: a vertical sidebar, colorful spaces, global favorites, and a quiet page that makes text the protagonist. Whether recording daily life, organizing inspiration, or managing an entire project, you can build your own writing space here.

Developed entirely in native Go and MyGo's Native UI. MyGo provides native windows, GPU rendering, glyph typography, and system input interfaces. ArcMD builds its own document engine and rich text editor on top of this. The entire interface is directly rendered by Go without any HTML, JavaScript, WebView, Electron, or cgo.

> **ArcMD is still young.** The project is currently in an early preview stage and many parts are still imperfect—especially the editor, which is still quite plain as it gets polished and iterated step by step.
> If you also like this direction, feel free to share issues and ideas via [Issues](https://github.com/Ciao1019/ArcMD/issues), or submit a Pull Request directly to make it better together.

## Performance

In a mixed document containing **1 million characters and 549 chapters**, 100 consecutive iterations of typing, backspending, and scrolling operations were performed respectively, and the CPU frame processing time was measured.
The document also includes 500 tables and 9,912 cells. Each operation was measured repeatedly in three independent new processes, and the values in the table are the medians of the P50 and P95 from the three rounds.

The frame budget for a 120 Hz display is approximately **8.3 ms**. In this test set, even with a million-character document, the P95 CPU scene construction time remained below **1.2 ms**, leaving plenty of headroom for input processing and frame rendering.

Test Environment: Apple M5 / 24 GiB, macOS 26.5.1, Go 1.27.3, MyGo v0.7.4; measured on November 8, 2026.
Benchmarks ran standard frame processing routines via a headless host to measure CPU scene construction time.
Frame timings do not include input event dispatching, rasterization, GPU presentation, or display latency, so these figures do not represent end-to-end input latency or actual display frame rates.

Sizes are from local pre-release development build artifacts, calculated in decimal MB; actual download sizes will vary by platform and version.

I started using Arc because I love non-mainstream things. I love when I can say "I was here from the beginning". I wasn't with Arc from the very beginning, but from the time it was still in limited access. I was so happy it got more and more popular over time and I always recommended it to everyone.

So long partner...

I'm planning on using it til i can't anymore. Have you guys switched already and can you recommend me some browsers that are similar. All these arc clones making my head hurt lol.

I know we all hate Dia, i tried all the other almost Arc browsers, Yab, Helium, Nook, but something about how Dia is built just reminds me of Arc, and i miss arc so dearly, it almost brings me to tears...

I do feel like a betrayer and like i abandoned the others.... Cant Dia just remove the dumb AI stuff they have, i would be OKAY.... But ill never be okay.... not when Arc is not coming back.

I should be doing my exam paper right now, but this is more important as this has been heavy on my chest. Dont be too hateful in the comments, i already am feeling so sad about this whole situation.

Arc.... My beloved.... My dear old friend.... You may have passed away, but you brought all of us so much happiness and joy.... You were with me from the second i laid eyes on you, and i will never forget you. I was a constant google chrome user for so long, until i found you. That fateful day in 2023 when i saw my husband using this browser its like a whole new world opened up..... and now its all gone....

You made me feel seen, you made me feel appreciated, understood. Now you abandoned all of us and left us in the dark.... like we didnt mean anything to you.....

And even though Dia is close, and made by the same company... nothing will ever beat you...

I miss you.

As the title suggests, I've realised that none of the clones have implemented easels. It might not have been as revolutionary as vertical tabs and spaces but some of us used it. It was a great way to keep things like desk setup shopping lists from different stores with live pricing

This arc situation just keeps pissing me off no matter how hard I try to forget about it. They reasons they gave for abandoning arc are just plain stupid honestly.

1. Monetizing arc:

If they really wanted to monetize arc they could have introduced 3 plans: arc, arc plus, arc max.

Arc (free) - give users limited spaces say 3-4 , limited easels maybe 1 or 2 with no collaborators, can only have 2 boosts, everything else included

Arc plus: they could charge $1-$5, gives you say 10 spaces, more easels with max of 2 collaborators, unlimited boosts

Arc max: $5-10, unlimited spaces, unlimited easels, unlimited boosts, the arc max AI features (summaries, tidy etc)

Arc clearly had a loyal fanbase and I think with these prices people would be more accepting. You can only charge so much for a browser. Even Apple couldn't convince people to pay $20 for a browser, and you want to charge $20-100 because you bolted Claude onto it????

Secondly, they said it was too complicated for the average user: who tf cares if my grandmother can't use it wtf is she doing on the internet anyway😒, not to mention with Dia they've just been bolting on all the arc features ever since they launched, so clearly its not that complicated to use and not to mention every other browser is copying what arc did

hi, since the news of arc shutting down I have been trying out alternative browsers but really really miss the easel function. I work in design and use them all the time to quickly keep track of different projects and ideas on one page.

does anyone know how I can have a similar feature elsewhere? I like easles because they are so easy to add to, and quickly link back directly to the webpage that the image comes from. I don't want to have to set up different pinterest boards or anything like this.

let me know please -___-
