Horse Browser is a terrible Arc Browser alternative

You are looking for an Arc Browser alternative. Most lists will tell you Zen, Vivaldi, or Brave. Horse Browser is on this list for one specific reason, and most of you should not pick it.

Arc is no longer being actively developed. The internet is full of "best Arc alternatives" articles, and they all recommend the same six skinned Chromiums with a sidebar.

Horse Browser is not on those lists. It shouldn't be. We are a terrible Arc Browser alternative. Let me explain why, in case you are about to make a mistake.

Arc's actual audience was tech nerds who like having a fresh browser icon in the dock. People who try every Product Hunt launch. People who run four browsers at once². For that audience, Arc was a treat. Sidebar tabs, pretty aesthetic, Boosts, Spaces, Easels, a small parade of features to demonstrate to a friend at a coffee shop.

And then, around month three, most of those users quietly went back to Chrome or Safari. Arc wasn't solving a real problem for them. It was just new. Novelty wears off. We've all been there³.

That audience isn't really a market. It's a hobby. The honest answer to "what's a good Arc alternative?" for most former Arc users is go back to Chrome. You weren't a person who needed a different browser. You were a person who liked having a different browser. Those are different conditions, and there is nothing wrong with the second one.

If you used Arc because you liked having a cool browser, Horse Browser is going to disappoint you in a number of specific and well-engineered ways.

There are no Boosts. Boosts were genuinely cool, by the way; the Browser Company shipped one of the most fun customisation systems any browser has ever had. We just don't have them, because they would be the wrong feature for the people Horse is built for. There is no Split View, no Easels, no AI in the address bar. The UI is intentionally plain⁴. If you bring up Horse Browser at a dinner party, people will say "oh, neat" and change the subject. That's fine. That's the design.

Every feature Arc added to feel exciting is a feature that would make Horse worse for its actual audience. Yeah, we thought about that. That's the whole job.

Horse Browser is for people whose brain genuinely does not work with tabs. Not "tabs are annoying." Genuinely does not work. Adults with ADHD or autism who have spent twenty years being told to focus harder, organize better, close some tabs, use a tab manager, install a different tab manager, try a Pomodoro timer, take a productivity course, and possibly meditate⁵.

That's Carol⁶. That's me. That's the audience.

Horse doesn't fix tabs. It replaces them with Trails: a branching tree that shows how you got from one page to the next, keeps every page you've opened visible, and lets you collapse the ones you don't need right now without losing them. It does not make browsing fancier. It makes browsing not hurt.

A psychotherapist with ADHD calls this externalizing executive function⁷, the browser holding the structure of your thinking so your ADHD brain doesn't have to.

If Horse isn't right for you, and statistically it isn't, here is the honest take on the rest of the field, written by someone who has tried all of them and is not paid by any of them.

If your Arc-shaped hole was about visual design, Zen is your answer. If it was about features, Vivaldi. If it was about not having to choose, Safari. Horse Browser is the answer to a different question entirely⁹.

Arc's one real insight was that Chrome's tab bar from 2008 is bad UX. Moving tabs to a sidebar, grouping them into Spaces, putting some breathing room around them, gestures in the correct direction. They just didn't go far enough. A Space is still a container full of flat tabs. The moment you click a link, your context still vanishes.

If you were one of the rare Arc users who picked it up because Chrome's tab bar was actively causing you stress, not because it looked good in screenshots, but because it hurt, then you and Horse might have something to talk about. There are not many of you. You know who you are.

The "Why it existed" row is the one that matters. Arc was built to be a better-designed Chrome. Horse is built for an audience that needed Chrome to stop being Chrome. That shapes every decision, including, especially, which features never get built.

Horse Browser doesn't punish you for having too many tabs. It doesn't block distracting sites. It doesn't shame you for falling down a rabbit hole at 2am. It assumes your brain works the way it works and tries to make the browser follow along.

If you want a visually exciting browser to replace Arc in your dock, Horse Browser is not the answer. Try Zen. Try Vivaldi. Go back to Chrome. We won't judge you. Much.

If tabs have been hurting your brain for years and nobody has taken that seriously, that's who I built this for. Try it free for two weeks. Card upfront, cancel any time before it bills, pay nothing if it isn't for you. That is the entire pitch.

For most ex-Arc users, Zen Browser is the closest visual and functional successor, open-source, Firefox-based, sidebar-driven. Vivaldi is the best for customization power users. Safari is the best if you want to stop thinking about browsers. Horse Browser is the right answer if and only if your problem with Chrome was that tabs themselves hurt your brain.

No. Arc kept the tab model and made it prettier. Horse Browser replaces tabs entirely with Trails: a branching tree that keeps every page you've opened visible. Different paradigm, different audience.

There is a two-week free trial. It does ask for a credit card upfront, we are an indie company, not a charity, and you can cancel any time before the trial ends and pay nothing. After the trial, it is $70/year. We charge because we plan to still be here next year.

Yes, probably. Arc didn't fix the underlying problem (tabs are still tabs in a sidebar). Horse does, and it was specifically designed by someone with ADHD for ADHD brains. Two-week trial, cancel any time before it bills. Worst case you find out it isn't for you and lose nothing but a few minutes of setup.
