In-Depth Overview
What is Orion?
Orion is Kagi's free, zero-telemetry browser for macOS built on WebKit, the same engine as Safari. That choice makes Orion exceptionally fast and power-efficient on Apple Silicon, with native macOS idioms, vertical tabs, Workspaces, and support for both Chrome and Firefox extensions — a rare combination. Privacy is central: Orion blocks trackers by default, ships without telemetry, and avoids the Chromium monoculture while retaining broad extension compatibility through Kagi's compatibility layers. Kagi Search is the default but you can set any search engine. Orion 1.0 launched 27 November 2025 after an extended beta; coverage from 9to5Mac, AppleInsider and others positioned it as a surprisingly good Safari alternative that feels more capable without sacrificing macOS integration. On macOS Tahoe 26 Orion is a native Apple Silicon app, notarised and actively maintained, with releases through 2026 and a new Linux public beta for those who want parity beyond Mac. The optional Orion+ subscription costs $5 per month or $50 per year and directly funds development; it is not required to browse. For Mac users who value WebKit efficiency, dual extension support and a privacy posture that is not just a Chromium preference toggle, Orion is one of the most interesting living alternatives to Safari in 2026.
What is Arc?
Arc is The Browser Company's free Chromium browser that defined the spatial browsing era on Mac. Its hallmarks are Spaces (themed desktops for work and personal), a vertical sidebar with pinned tabs, Split View for side-by-side pages, Peek for hover previews, Boosts for per-site customisation, Easels for lightweight canvases, and a command palette that made switching contexts feel calm. Between 2022 and 2024 Arc set the bar for browser UX and spawned an entire generation of Arc-inspired designs. As of May 2025 The Browser Company moved Arc into maintenance mode to build Dia. Official messaging in August 2026 is consistent: Arc receives Chromium security updates only, while feature development and the company's AI browser narrative live in Dia, which requires Apple Silicon and macOS 14 or later. Arc still installs on Intel and Apple Silicon Macs with Tahoe 26, still supports Chrome extensions, and still feels polished, but it is a frozen product. The consequence for new installs is straightforward: Arc is legacy software to appreciate and migrate from, not to adopt. Existing Arc users should export bookmarks, document Spaces and plan a move to Dia if eligible, or to Orion, Zen Browser, Vivaldi or Brave for a living alternative that continues to receive feature and security investment.
Detailed Feature Comparison
Development status & security
CriticalActively developed under Kagi with Orion 1.0 in November 2025 and continued 2026 updates including a Linux public beta. Native Apple Silicon, notarised, and iterated on WebKit compatibility.
Maintenance mode since May 2025. Chromium updates only with no feature roadmap. Company directs users seeking active development to Dia.
Verdict: Orion is the living product. Arc's maintenance posture cannot be recommended for a new default.
Browser engine & web compatibility
HighWebKit gives Safari-like efficiency and macOS integration. Broad compatibility with dual Chrome and Firefox extension support, though the rare Chromium-only site may still need a fallback browser.
Chromium baseline with strong site compatibility via Chrome engine. Frozen chrome beyond Chromium bumps.
Verdict: Trade-off: Arc's Chromium is more universally compatible; Orion's WebKit is more efficient and Mac-native but occasionally requires a second browser for a Chromium-only quirk.
Tab & workspace organisation
HighVertical tabs, Workspaces and tree-style organisation with macOS-native feel. Designed around focus without replicating Arc's heavy chrome.
Spaces, sidebar, Split View and Peek remain the most polished spatial UX in the category even though frozen. Still the aesthetic benchmark.
Verdict: Arc wins pure spatial nostalgia. Orion is the closest living analogue with a lighter, more native implementation.
Privacy & telemetry
HighZero-telemetry by policy, tracker blocking by default, and no Chromium data surface. One of the strongest privacy pitches among Mac browsers without going full Tor.
Respectable Chromium privacy posture historically but not a privacy leadership project and not iterated in 2026.
Verdict: Orion is the privacy-native choice. Arc's privacy is conventional Chromium.
Extensions
HighRare dual support for Chrome and Firefox extensions on WebKit. Covers most daily drivers without a Chromium install. Compatibility layers continue to improve.
Chrome Web Store compatible. Broad catalogue but Chromium-only.
Verdict: Orion's dual-extension story is more versatile if you mix ecosystems.
Performance & battery on Mac
MediumWebKit efficiency with excellent Apple Silicon tuning and low idle power. Consistently praised as faster and lighter than Chromium for typical browsing on MacBooks.
Chromium baseline; perceived lightness depends on Spaces discipline. More memory pressure when many Spaces stay alive.
Verdict: Orion wins battery and responsiveness on MacBooks for typical browsing loads.
AI assistance
MediumKagi services integration with Kagi Assistant and summarisation where configured, but not an AI-browser narrative. Focus is browsing excellence and privacy.
Arc Max AI experiments are frozen. The company's AI browser work is in Dia, not Arc.
Verdict: Neither is an AI-browser leader in this pair; Orion's Kagi integration is at least living, while Arc's AI is legacy.
Platform & pricing
MediumFree with optional Orion+ around $5/month or $50/year to fund development. Primary platform is macOS with a new Linux public beta; Windows story remains limited.
Free Mac and Windows clients. Dia successor is Apple Silicon macOS 14+ only, narrowing the Browser Company future for Intel Mac users.
Verdict: Both are free to browse. Orion funds development via optional subscription; Arc's successor is platform-restricted.
Who Should Choose Which?
1Privacy-conscious freelancer on MacBook Air
Zero-telemetry, tracker blocking and WebKit efficiency give you Safari-like battery with stronger privacy and dual extension support.
2Designer wed to Arc Spaces
Orion's Workspaces are the closest living analogue without Chromium overhead. If you need The Browser Company's exact metaphor, try Dia on Apple Silicon, but do not start a new long-term setup on Arc.
3Developer who needs Chromium-only testing
Use Orion as daily driver for efficiency and install Edge or Brave for Chromium-only sites and Chrome extension edge cases. Arc alone no longer covers the living Chromium need.
4Kagi Search subscriber
Tight Kagi integration, Kagi Assistant and Orion+ funding align naturally with a Kagi-centred workflow on Tahoe 26.
5Existing Arc user with heavy customisation
Screenshot Spaces and Boosts, export bookmarks, trial Orion vertical tabs and Workspaces for a week, and decide between Orion, Dia, Zen Browser or Vivaldi for the long term.
Migration Guide
Arc → Orion
Export bookmarks and passwords from Arc, note Spaces and Boosts layout, install Orion via Homebrew or Kagi's disk image (brew install --cask orion), set default search, enable vertical tabs and create Workspaces that mirror your Spaces, install core extensions from both Chrome and Firefox stores, and run Orion as default for a week with Arc kept read-only.
Orion → Arc
Not recommended for new users in 2026. If testing Arc for historical comparison, install knowing updates are Chromium-only and evaluate Orion or Dia as the living alternative.
Final Verdict
orion
Winner
Runner-up
Orion is the clear pick for a new Mac default in August 2026. Its WebKit-native, zero-telemetry design with vertical tabs, Workspaces and dual Chrome plus Firefox extension support delivers a fast, private and actively developed experience on macOS Tahoe 26 that Arc, as a beautiful but frozen Chromium product, cannot match. Arc's spatial UX still charms, but its maintenance-mode status means it is a legacy to migrate from, not to standardise on.
Bottom Line: Install Orion for a private, Mac-native daily browser. Keep Arc only as a read-only bridge while you rebuild Workspaces in Orion or trial Dia if you specifically need The Browser Company's next chapter on Apple Silicon.
