Notes 
Orion is a WebKit-based browser built by Kagi, targeting macOS and iOS. It collects no telemetry, ships with built-in ad and tracker blocking, and is the only browser that can load extensions written for Chrome, Firefox, and Safari side by side. No account is needed to use the free tier; an optional paid subscription unlocks additional Kagi services.

Our take
The extension compatibility story is genuinely unusual: running uBlock Origin alongside a Safari extension in a WebKit shell is something no other browser offers. Privacy defaults are strong out of the box and the zero-telemetry claim is matched by the business model (user-funded, no ad deals). The honest catch is that Orion is closed-source, so the telemetry-free assertion cannot be independently verified at the code level. It suits macOS and iOS users who want Chrome-extension reach without Chromium, and who are comfortable trusting a small commercial vendor.
