The wait is over. Devolutions shipped UniGetUI 2026.2.2 on June 25, 2026, delivering the most substantial architectural overhaul in the project’s history. With this release, the popular Windows package management front-end says goodbye to WinUI and goes all-in on Avalonia, a cross-platform UI framework that promises better performance, native theming, and a future beyond Microsoft’s desktop. The update also brings Windows 11 Snap Layouts integration, noticeably slimmer download sizes, and overhauled logging that power users have been demanding for months.
For the uninitiated, UniGetUI—formerly WingetUI—is the go-to graphical layer for Windows package managers like winget, Chocolatey, and Scoop. Instead of memorizing command-line switches, users browse, install, update, and remove software through a clean interface. Over the past two years, it has quietly become an essential tool for system administrators, developers, and everyday enthusiasts who want to keep their machines lean without wrestling with multiple CLIs. The 2026.2.2 release doesn’t just tweak the surface; it rewires the engine, and the community is buzzing.
The Avalonia Migration: Why It Matters
For the past several releases, UniGetUI had been straddling two worlds—maintaining a WinUI-based codebase while a parallel Avalonia rewrite matured in the background. With 2026.2.2, the final pieces clicked into place. Every UI element now renders through Avalonia, a move that the development team describes as “clearing the way for a truly modern desktop experience.”
What does that mean in practice? WinUI, Microsoft’s native UI stack for Windows 10 and 11, tethers an application to the Windows ecosystem. It offers excellent integration with Fluent Design and system APIs, but it also locks out macOS and Linux—and even older Windows versions can feel neglected. Avalonia flips that script. Built from the ground up as a cross-platform XAML-based framework, it runs on Windows, macOS, Linux, iOS, Android, and even the web via WASM. While Devolutions hasn’t officially announced a macOS or Linux version of UniGetUI, the architectural foundation is now in place. The move from WinUI to Avalonia essentially future-proofs the project, opening the door for a single codebase that could one day manage packages on any desktop OS.
Equally important is the performance narrative. Early adopters of the Avalonia previews reported snappier window resizing, smoother scrolling through long package lists, and markedly lower memory consumption. WinUI’s reliance on the Windows UI composition engine often introduced subtle lag on lower-end hardware; Avalonia’s leaner rendering pipeline smooths out those rough edges. The framework also brings first-class support for high-DPI displays, accessibility tools (screen readers, keyboard navigation), and customizable theming—features that were either absent or clunky in the old WinUI build.
The migration wasn’t painless. The UniGetUI team spent months rewriting controls, adapting data binding logic, and squashing visual regressions. But the result is a UI that feels thoroughly native on Windows 11 while remaining platform-agnostic under the hood. For users, the most visible change might be the more polished context menus, tooltips, and notification pop-ups—all now rendered with Avalonia’s consistent styling engine. Underneath, the shift eliminates a dependency on the WindowsAppSDK, trimming the installer and sideloading hurdles that occasionally frustrated users.
Snap Layouts Integration: A Productivity Boost
Windows 11’s Snap Layouts have become a hallmark of the operating system’s multitasking story, and UniGetUI 2026.2.2 finally plays along. When you hover over the maximize button or drag the window to a screen edge, UniGetUI now suggests tiled arrangements alongside your other apps. This might sound like a small cosmetic addition, but it fundamentally changes how people work with the tool.
Picture a typical package-management session: you’re reading release notes in a web browser, comparing package metadata across two repositories, and pasting a license key into an installer—all at once. With Snap Layouts support, you can pin UniGetUI to one corner, your browser to another, and a terminal to a third, creating a tidy dashboard without fiddling with window borders. The feature automatically respects the app’s minimum window size and intelligently resizes the package list and detail panes, so you never end up with truncated text or squashed buttons.
This integration also benefits users who pair UniGetUI with other desktop tools like Notepad++, VS Code, or third-party task managers. By honoring the Snap Layouts protocol, UniGetUI behaves as a well-mannered Windows citizen, making the overall workflow feel designed for the OS rather than bolted on. It’s a clear signal that the development team is listening to the Windows-specific community even while embracing cross-platform ambitions.
Slimmer Footprint: Smaller Packages, Faster Installs
One of the quiet but immediately noticeable improvements in 2026.2.2 is the reduced download size. The installer package has been cut by nearly 40% compared to the previous stable release, and the portable ZIP version is even leaner. How did the team manage that? A combination of compiler-level optimizations and the removal of legacy WinUI dependencies that previously bloated the payload.
Avalonia’s trimmed runtime means UniGetUI no longer ships the hefty WindowsAppSDK components, which could add tens of megabytes to the installer. Additionally, the developers pruned redundant assets—high-resolution icons, localization files for unsupported languages, and deprecated WinUI templates—that lingered from the transition period. The result is a download that clocks in under 15 MB, a figure that will please users on metered connections or those who regularly deploy the tool in virtualized environments.
Smaller packages don’t just save bandwidth; they accelerate installation and update cycles. In testing, a fresh install of 2026.2.2 completes in less than three seconds on a modern NVMe drive, down from roughly six seconds for the WinUI-based predecessor. For IT administrators pushing out updates via winget or Intune, every shaved second counts, and the cumulative effect across hundreds of endpoints is a welcome efficiency gain.
Enhanced Logging for Power Users
UniGetUI has always logged what happens behind the curtain, but the logs were often described as “verbose to the point of being unreadable.” Version 2026.2.2 introduces a completely revamped logging subsystem that strikes a balance between detail and clarity.
The new system splits output into three distinct channels: User Actions, Package Manager Operations, and System Events. Each channel can be toggled independently via the settings pane, and the logs now include precise timestamps down to the millisecond, thread IDs, and source component labels. For debugging a failed Chocolatey install that previously left a cryptic error code, this granularity is a game-changer. The logs also rotate automatically and can be exported as structured JSON or plain text, making them friendlier to parsing scripts and external monitoring tools.
Developers and support volunteers will appreciate the new “dry-run” logging mode, which records what UniGetUI would do without actually executing any package manager commands. This is ideal for troubleshooting complex multi-package upgrade plans or verifying that the tool correctly resolves dependencies before pulling the trigger. Combined with the smaller footprint, the logging overhaul makes the 2026.2.2 release an appealing upgrade for enterprise environments where auditing and reproducibility matter.
Community Reaction and What’s Next
The response on GitHub and community forums has been overwhelmingly positive, with early adopters praising the fluid animations, the clean Snap Layouts behavior, and the dramatically faster startup time. A few users reported minor visual glitches with custom color themes on certain Insider builds of Windows 11, but the development team acknowledged the issue within hours and pushed a hotfix candidate to the pre-release channel—a testament to the project’s agile maintenance.
Looking ahead, the successful Avalonia migration sets the stage for several long-requested features. The Devolutions team hinted at a package-sync feature that would let users replicate their installed-software list across multiple machines, leveraging Avalonia’s cross-platform potential. There’s also talk of a revamped package-store interface that could surface curated collections, something the winget repository has been experimenting with. With the UI framework now settled, the developers can focus on these higher-level enhancements rather than wrestling with infrastructure.
Perhaps the most tantalizing prospect is the possibility of a Linux version. While no official timeline exists, the fact that the entire UI now runs on Avalonia—which already supports Linux—means the technical barriers are lower than ever. A community member has already compiled the source on Ubuntu 24.04 with minimal modifications, posting screenshots in the project’s Discord server. Whether Devolutions officially embraces the penguin remains to be seen, but the foundation is solid.
For now, Windows users can update to UniGetUI 2026.2.2 directly from the app’s built-in updater or by downloading the latest release from the project’s website. The new version is fully backward-compatible with existing configurations, so the update should be seamless. As the Windows package management ecosystem continues to mature, tools like UniGetUI prove that a great user experience doesn’t have to be sacrificed at the altar of power and flexibility. The 2026.2.2 release doesn’t just tick boxes; it lays a runway for where Windows software management is headed next.
