Orion Browser

Every iOS browser is Safari wearing a different coat. Apple mandates WebKit under the hood, so Chrome, Firefox, and Edge on iPhone are essentially reskins with sync bolted on. Kagi Inc. — the small, search-subscription company that’s spent the last few years proving people will pay for a search engine without ads — looked at that constraint and asked a different question: if we’re stuck with WebKit anyway, why not build the best possible WebKit browser instead of a worse Safari?

Orion Browser is the answer, and it’s a different proposition from anything else in the App Store. It’s free, funded entirely by user tips and an Orion+ supporter tier rather than advertising or data harvesting. That funding model isn’t a footnote; it’s the whole thesis. Orion ships with a strict zero-telemetry policy — no analytics, no crash-reporting-that’s-actually-tracking, nothing phoning home — plus built-in ad and tracker blocking that works out of the box.

The headline act, though, is web extension support on iOS. Orion can install many Chrome and Firefox extensions directly on an iPhone or iPad. Not “content blockers.” Not Safari’s walled extension garden. Actual WebExtensions from the stores you already know. Nobody else on iOS does this at scale, and it fundamentally changes what a phone browser can be.

A companion macOS build is distributed directly from browser.kagi.com (deliberately outside the Mac App Store), with Windows and Linux versions in development. Android? Kagi has confirmed it’s not being built — and the similarly named browsers on the Play Store are impostors. Buyer beware.

• Real extension support on iOS: Install many Chrome Web Store and Firefox Add-ons extensions natively on iPhone and iPad — a capability effectively unique in mobile browsing. Compatibility isn’t universal, but when it works, it changes what mobile browsing can do.
• Zero telemetry, by design: Orion collects no user data. Period. Combined with aggressive built-in ad and tracker blocking, pages are stripped of clutter before anything loads, without installing a single thing.
• Native WebKit foundation: Orion behaves like a supercharged Safari — same rendering engine, same scroll physics — layered with global page zoom, focus mode, flexible search engine choices, and deep customization Safari refuses to offer.
• User-funded, ad-free business model: Free to use, sustained by tip-jar purchases and the Orion+ tier. No advertiser sits between you and the product roadmap.

The Extension Gambit

Extensions matter here for a simple reason. On desktop, they’re table stakes. On iOS, they’ve been a fantasy for fifteen years. Apple’s Safari extension ecosystem is thin and gated behind Mac-centric developer tooling; every other browser gets nothing at all. Orion’s engineers built a WebExtensions compatibility layer on top of WebKit, which means a meaningful slice of the Chrome and Firefox catalogs — password tools, page manipulators, userscript managers, niche utilities — can run on a phone.

The honest caveat: “many” is not “all.” Extensions written against desktop assumptions — persistent background pages, specific Chromium APIs, UI that expects a mouse — can break, misrender, or drain battery. Orion doesn’t hide this, and the community has effectively crowdsourced a compatibility map. Treat it as a superpower with a success rate, not a guarantee. Even at a partial hit rate, it’s more than any competitor offers.

Privacy as Architecture, Not Marketing

Every browser claims to care about privacy now; it’s the industry’s most devalued word. Orion’s claim is structurally different because of who’s making it. Kagi’s entire business is users paying directly for tools, which means there is no advertising revenue to protect and therefore no incentive to collect anything. The zero-telemetry stance isn’t a settings toggle — it’s the absence of the plumbing entirely. The built-in blocking is aggressive enough that most users should never need to install an ad blocker, which conveniently sidesteps the extension-compatibility question for the most common use case.

The Power-User Problem

Here’s where the critical eye earns its keep. Orion is unapologetically a power-user browser, and that cuts both ways. Global page zoom is the kind of accessibility-adjacent feature Apple should have shipped years ago. Focus mode and per-site controls reward people who tune their tools. But that same ambition strains a small team: the store rating (4.0 stars across 1,145 ratings) reflects occasional crashes and stability wobbles among the most common complaints, and the wishlist is long — isolated profiles with separate cookies and history, tab groups, customizable toolbars. None of these are dealbreakers, but they’re the tax for choosing a browser built by a company a fraction of Google’s size. If the priority is frictionless and boring, Safari is right there. Orion asks for a little patience in exchange for a lot of capability.

The Sustainability Question

The tip-jar model is admirable and fragile in equal measure. Kagi has a paying search subscriber base subsidizing the vision, which makes Orion more durable than the average indie browser. But users should understand what they’re buying into: a roadmap paced by a small team’s bandwidth, not a FAANG-scale release train. The upside is that the roadmap answers to users. When funding comes from the people using the product, “engagement metrics” stop being a design input. That’s rarer than it should be.

Orion’s aesthetic philosophy is restraint. It’s built as a native Apple app in the ways that matter — WebKit rendering, platform-standard gestures, no Chromium-transplant jankiness. As a WebKit browser of this scope, it’s light on hardware, and its battery profile should track Safari’s, which is the correct benchmark on this platform. The built-in blocking is, by design, the cheapest performance optimization in computing: stripping trackers before they load rather than after.

The flip side: stability doesn’t yet match Apple’s own browser. Crashes are the most common complaint in reviews, and while they’re occasional rather than chronic, Safari’s rock-solid baseline makes every stumble conspicuous. Extension-heavy configurations amplify the risk. This is beta-adjacent software in polish, if not in label.

One oddity worth flagging: the App Store presence itself is spartan — minimal marketing assets, no screenshot carousel theatrics. That’s on-brand for a company allergic to marketing, but it does the product no favors with first-time browsers.

On iPhone, Orion is essentially Safari with the governor removed. The touch-first chrome stays out of the way, and features like global zoom matter enormously on a small screen. Extensions designed for desktop widths can get awkward here — popup UIs built for large screens can render cramped — so temper expectations for complex add-ons.

On iPad, the proposition strengthens considerably. More screen real estate means desktop-class extensions behave closer to their intended design, and an iPad with a keyboard running Orion plus a userscript manager comes close to a laptop browsing experience. For anyone trying to make an iPad a primary machine, Orion makes a strong case that it’s possible.

The macOS version exists but lives outside this review’s scope — and outside any app store, distributed straight from Kagi. Android users are out of luck entirely, and Kagi has said plainly that’s not changing. Anything named “Orion” on the Play Store is not this browser.

Orion is the most distinctive iOS browser available, and it isn’t a close call. Kagi took Apple’s WebKit mandate — the constraint that made every third-party iOS browser pointless — and built something with an actual reason to exist. The extension support alone justifies the install for anyone who has ever wished a desktop extension existed on a phone. The zero-telemetry architecture, backed by a business model that makes surveillance economically pointless, gives the privacy pitch teeth that Chrome’s and Edge’s marketing departments can’t match.

It is not finished software in the way Safari is finished. Stability lags Apple’s baseline, the feature wishlist is long, and the team is small. Mainstream users who just want to tap and scroll should stay with Apple’s default and lose nothing. But for the audience Orion is actually built for — people who live in their browser and resent being the product — it’s the only solid alternative on iOS. It’s the only one making a real argument, and for that audience, it earns a recommendation.
