AssetRipper

AssetRipper is a Unity game-file analysis and export tool for developers and people working with game assets. It is best suited to inspecting Unity files, extracting content in batches, or bringing exported assets into Unity or Blender.

Overview

AssetRipper handles CAB-*, .assets, .sharedAssets, .unity3d, and .bundle files, with batch extraction across asset types including audio, fonts, images, models, shaders, sprites, terrain, scenes, and prefabs. Its analysis can uncover accidentally included dependencies, broken asset references, and code that could not be inlined or trimmed—useful checks for developers auditing game files.

Unity support runs from version 3.5.0 to 6000.4.X, but support quality varies. Modified bundle formats can also stop loading: prepended null bytes and whole-file encryption are examples. The wide version range is therefore a starting point, not a guarantee that every file will work.

Key features

Unity Project Export creates a project that opens in Unity Editor, which is the better route when you need to continue working with assets in Unity. Primary Content Export is aimed at viewing content elsewhere: it exports meshes, scenes, and prefabs as GLB models, including for Blender. That separation gives users a clear choice between a Unity project workflow and a more portable viewing workflow.

AssetRipper supports GLB and Unity YAML models, and BMP, EXR, HDR, JPEG, PNG, and TGA textures. Premium tools add shader decompilation, static mesh separation, prefab outlining, traditional Il2Cpp analysis, asset path overrides, user-defined package export, and asset deduplication. Deduplication covers only Mono Scripts, Shaders, Compute Shaders, Audio Clips, Text Assets, Meshes, and Textures without sprites, so it is not a comprehensive pass across every asset type.

Shader decompilation is platform-dependent: Vulkan and OpenGL shaders can be decompiled on any platform, while DirectX shaders require Windows. Traditional Il2Cpp analysis is a particularly limited reason to pay: it currently succeeds on about 10% to 20% of methods on x86 games and less often on other platforms.

Pricing

AssetRipper Free costs nothing and includes stable and nightly builds for Windows, Mac, and Linux. It is the sensible starting point for extraction, Unity project export, and primary content export without paying for premium analysis tools.

AssetRipper Premium costs $10 a month, billed $10 per month, and requires an active membership through Ko-fi, Buy Me a Coffee, GitHub Sponsors, or PayPal. It adds the premium features, making it relevant to users who specifically need those tools; Windows users have the broadest shader-decompilation support. The stated pricing gives no seat or usage quota terms, so those should not be assumed.

Platforms

AssetRipper offers builds for Windows, Mac, and Linux. DirectX shader decompilation is Windows-only, while Vulkan and OpenGL shader decompilation works on any platform. Traditional Il2Cpp analysis has lower success rates outside x86 games, so platform choice matters for that feature as well.

Who it's for

Choose AssetRipper if you need to inspect Unity game files, export a project for Unity Editor, or view selected meshes, scenes, and prefabs outside Unity. Developers auditing dependencies and references have a clear use for its analysis functions, while Blender users can use GLB exports to view content. It is a poorer fit if your bundle files have incompatible changes or if you need reliable, broad Il2Cpp method analysis.

Pros and cons

• Broad Unity-version coverage: support spans versions 3.5.0 to 6000.4.X, though quality varies.
• Two useful export routes: export a Unity project or GLB content for viewing outside Unity.
• Batch extraction across many asset types: helpful when processing multiple files, with supported formats including images, audio, models, shaders, and scenes.
• Important compatibility and analysis limits: altered bundle formats may not load, and Il2Cpp analysis succeeds on only about 10% to 20% of methods on x86 games, less on other platforms.
• Premium tools are gated: shader decompilation and other advanced features require an active paid membership, and some shader support is Windows-only.

Alternatives

• Source 2 Viewer is a free, open-source, reverse-engineered option for readers working with Source 2 content instead of Unity files.
• SLADE3 is a free desktop editor for readers looking for that kind of editor; beta builds may have bugs, crashes, and unfinished features.
• OpenKh is a free option for readers who need software under Apache-2.0 and can use its required .NET 8.0 Runtime.
• Rusted PackFile Manager is a free alternative for readers seeking software under the MIT License, which permits use, copying, modification, distribution, and sale with a copyright notice.
• arcdEx is a free Linux alternative.

Verdict

AssetRipper is a strong fit for Unity-focused users who need file analysis plus a choice of Unity project export or GLB viewing exports, and its free desktop builds make it practical to start without a subscription. Look elsewhere if your bundles have incompatible alterations or if dependable Il2Cpp analysis is central to the job; the premium price does not remove those limits.
