Kagi Ends Development of Orion Browser for Linux and Windows, Plans to Open Source the Codebase

Kagi has officially announced that it is halting the development of its Orion web browser for Linux, bringing a swift end to an ambitious cross-platform expansion effort that captured the attention of open-source enthusiasts and privacy-conscious internet users alike.

The native GTK port of Orion for Linux was first announced in 2025, promising a web browsing experience built with distinct principles. Following months of anticipation, a public beta version was launched earlier this year, allowing early adopters on Linux distributions to test the software firsthand. The primary objective of the development team was to achieve full feature parity with the well-established macOS build of the browser. Recent beta releases had edged closer to realizing that ambitious goal, but ultimately fell short of the finish line—and according to company leadership, that is where development will permanently remain.

At least, that is the case for official corporate backing. In a surprising turn, Kagi has revealed that it plans to open source the Orion for Linux codebase, alongside its work-in-progress port of Orion for Windows. This move hands the project over to the broader Free and Open Source Software (FOSS) community, offering developers an opportunity to step up and carry the torch forward. However, the company was quick to acknowledge that developing and maintaining an independent web browser is an exceptionally difficult endeavor.

In a statement addressing the shutdown, Kagi highlighted the immense resource requirements of the browser market. Building a cross-platform web browser is something that is typically accomplished by massive corporations backed by substantial venture capital or by sprawling, well-funded open-source communities. Kagi noted that it is neither of those things. Instead, the company operates as a lean enterprise employing just a handful of developers, relying primarily on funding generated by users of its paid, privacy-focused search engine rather than advertising models or corporate venture funds.

Reflecting on the challenges of browser engineering, Kagi noted that life would have been significantly easier for their development team if they had chosen the path taken by most modern browser projects—building directly on top of Google’s Chromium engine. Instead, the company persisted in its efforts because it firmly believed that the modern web requires more than one dominant engine, and ideally, more than one independent company capable of shaping the future standards and appearance of the internet.

For many observers who have followed the browser ecosystem, the decision carries a sense of disappointment. On macOS, Orion has earned a reputation as a genuinely solid browser, blending performance with compatibility. Observers and supporters had remained hopeful that, despite the herculean task ahead of them, the Kagi team possessed the technical skills and visionary ideas required to pull off a Linux port successfully, even if progress was slow and methodical.

Orion for Linux is Finally Going Open Source

The open-sourcing of the Orion for Linux and Windows codebases introduces a bittersweet dynamic for the open-source community. Orion was not released as an open-source project from its inception. That proprietary initial approach had historically soured enthusiasm among strict FOSS purists who prefer transparent, community-governed software. Now, the news that the underlying code will be made freely available offers a silver lining, allowing the community to inspect, modify, and potentially resurrect the project under a new banner.

Kagi’s overarching business model is fundamentally tied to its user base. Funded directly by subscribers rather than advertisers, the company builds tools tailored strictly to what its paying customers desire, without the pressure to stuff user interfaces with attention-hijacking gimmicks, telemetry trackers, or intrusive partner deals designed to inflate advertising revenue.

Ironically, it is that very same user-focused business model that has ultimately pulled Kagi’s engineering focus back to its core offerings on macOS and iOS. Simply put, that is where the vast majority of Kagi’s paying user base resides, and the company must allocate its limited engineering hours where they provide the most direct value to the subscribers sustaining the business.

While the official Linux beta will receive no further updates, the decision to open-source the project may help drive independent efforts forward in some guise, or at the very least allow other independent web browser projects to pick through its architectural components for inspiration and reusable code.

Development on Orion for macOS and iOS remains entirely unaffected by this strategic shift, continuing forward as planned. However, Linux users who installed the public beta face a different reality. While they can technically continue running the software they have already downloaded, Kagi has explicitly stated that it does not recommend using the browser as a daily driver moving forward, as security vulnerabilities discovered from this point onward will remain unpatched.

Kagi has indicated that it will share more comprehensive details regarding the upcoming open-sourcing of the codebase within the coming month.
