Everything You Need to Know About Orion for Linux v0.3 Beta

Orion for Linux is a native GTK4/libadwaita web browser developed by Kagi, the company behind the popular search engine. It uses WebKitGTK as its rendering engine and aims to bring the feature set of the macOS version to Linux. The latest beta, v0.3, introduces a content blocker and download manager, along with improved stability for broader real-world use. Below, we answer common questions about this exciting new browser.

What Is Orion for Linux?

Orion for Linux is a web browser built natively for the Linux desktop using GTK4 and libadwaita libraries. It leverages WebKitGTK, an open-source engine, to deliver fast and standards-compliant web rendering. Kagi designed Orion to be a lightweight yet powerful alternative to browsers like Firefox and Chromium, with a focus on privacy and user control. The Linux version aims for feature parity with the established macOS version, though some platform-specific features (like integration with macOS keychain) are not available. The browser is currently in beta, with the v0.3 release representing a significant step toward a stable, polished product.

What’s New in the v0.3 Beta?

The v0.3 beta of Orion for Linux brings two highly requested features: a built-in content blocker and a download manager. The content blocker allows users to block ads, trackers, and other intrusive scripts directly within the browser, enhancing privacy and page load speeds. The download manager provides a clear interface to view, pause, resume, and organize downloaded files. Kagi states that this update makes Orion “much more capable” and ready for “broader, real-world use and feedback.” These additions join existing features like tab management, password manager, history tracking, and focus mode, rounding out Orion’s core functionality.

When Was Orion for Linux First Released?

Orion for Linux first appeared as an alpha build in early 2026. After gathering initial feedback, Kagi released the first beta in March of the same year. The v0.3 beta, which adds the content blocker and download manager, became available a few months later in mid-2026. This rapid iteration shows Kagi’s commitment to quickly maturing the Linux version. Users can download the latest beta from Kagi’s official website or package repositories.

What Core Features Does Orion Offer?

Orion for Linux includes a range of features designed for productivity and privacy. Key features include:

• Tab Management: Group tabs, pin them, and use vertical tab layouts.
• Password Manager: Built-in password storage and autofill with encryption.
• History Tracking: Browse history with search and filtering.
• Focus Mode: A distraction-free reading and browsing environment.
• Content Blocker (new in v0.3): Block ads and trackers.
• Download Manager (new in v0.3): Manage file downloads with ease.

These features work together to provide a smooth and secure browsing experience, comparable to what macOS users enjoy.

How Does the Linux Version Compare to the macOS Version?

Kagi aims for feature parity between the Linux and macOS versions of Orion, but platform-specific limitations apply. For example, the macOS version can integrate with Apple’s Keychain and use Safari extensions, while the Linux version uses its own password manager and supports WebExtensions. Many core features—such as tab management, content blocking, and focus mode—are identical across both platforms. The Linux version’s native GTK4/libadwaita interface gives it a natural look on GNOME desktops. Kagi continues to close the gap, and the v0.3 beta brings it much closer to the macOS edition.

Why Is Orion Built with GTK4 and libadwaita?

By using GTK4 and libadwaita, Orion for Linux ensures a native look and feel on GNOME-based desktops and other GTK environments. This approach differs from Electron-based browsers or those using custom toolkits, resulting in better performance and lower memory usage. The choice also allows Orion to respect system themes, fonts, and accessibility settings, providing a seamless user experience. Kagi views native integration as a priority for a browser that truly belongs on Linux.

What’s Next for Orion for Linux?

Kagi has not announced a specific roadmap, but the v0.3 beta is a clear step toward a stable release. Future updates may include extension support (like uBlock Origin), sync with Orion on macOS, and enhanced privacy controls. The company encourages users to try the beta and provide feedback to shape development. You can download the latest build from the Orion website and stay tuned for updates.
