Orion for Linux Beta v0.3: New Features and Development Updates

Welcome to the latest update on Orion for Linux! Kagi's native GTK4/libadwaita web browser has reached beta v0.3, bringing significant enhancements that move it closer to feature parity with its macOS counterpart. This release introduces a content blocker and a download manager, addressing key user needs for a secure and organized browsing experience. Below, we answer common questions about this new version and the browser's overall development.

What is Orion for Linux?

Orion for Linux is a web browser built natively for the Linux desktop using GTK4 and libadwaita, powered by the WebKitGTK engine. Developed by Kagi, the company known for its privacy-focused search engine, Orion aims to deliver a fast, lightweight, and secure browsing experience. It offers core features such as tab management, a password manager, history tracking, and a focus mode. The browser is designed to eventually match the feature set of the established macOS version, though platform-specific differences remain.

What's new in the Orion for Linux v0.3 beta?

The v0.3 beta marks a major step forward. Kagi says this build is ready for “broader, real-world use and feedback.” Key additions include a content blocker to protect against trackers and intrusive ads, and a built-in download manager that gives users more control over file downloads. These features were missing in earlier alphas and betas and significantly improve daily usability. The update also includes numerous under-the-hood stability improvements and bug fixes that make the browser more reliable for regular use.

How does Orion for Linux compare to the macOS version?

Kagi’s long-term goal is feature parity between the Linux and macOS editions, but some platform-specific features will naturally differ. The macOS version has been in development longer, so it currently offers a more polished set of capabilities. However, the Linux version is catching up quickly with the v0.3 beta adding critical tools like the content blocker and download manager that are already present on macOS. Linux users can expect a similar browsing philosophy: speed, privacy, and a clean interface, with a native GTK4 look and feel that integrates well with GNOME desktop.

What core browsing features does Orion for Linux already include?

Even before v0.3, Orion for Linux shipped with several essential features. These include tab management (including vertical tabs and tab groups), a built-in password manager, browsing history tracking, and focus mode for distraction-free reading. Additional highlights are a customizable new tab page and support for browser extensions (via a compatible WebExtensions framework). The v0.3 update builds on this foundation by adding the two headline capabilities, making the browser more complete for everyday use.

What is the development history of Orion for Linux?

Orion for Linux started with an alpha release in early 2026, allowing early adopters to test the browser’s core architecture. An initial beta launched in March of the same year. Since that first beta, Kagi says the browser “evolved into a much more capable browser,” with steady improvements based on community feedback. The v0.3 beta represents the latest milestone, focusing on key add-ons and stability. Kagi encourages users to try it and provide feedback to shape future releases as they work toward a stable version that matches the macOS edition.

Why is Orion for Linux built on WebKitGTK?

Kagi chose WebKitGTK as the rendering engine because it offers a strong balance of performance, standards compliance, and integration with GTK-based Linux desktops. WebKitGTK is the Linux port of Apple’s WebKit engine, which powers Safari. This choice allows Orion to be lightweight and energy-efficient while supporting modern web technologies. The use of GTK4 and libadwaita ensures a seamless visual experience on GNOME, making Orion feel like a native application rather than a port from another platform.

Who is behind Orion for Linux and what are their goals?

Orion is developed by Kagi, the company known for its privacy-respecting search engine. Kagi’s overarching mission is to provide tools that respect user privacy without sacrificing quality. With Orion, they aim to create a browser that is fast, secure, and free from the data mining common in many mainstream browsers. For the Linux version specifically, Kagi wants to offer a first-class browsing experience that feels native to Linux, with full feature parity with the macOS version over time. The v0.3 beta is a major step toward that goal.
