itch app vs Kenney Assets

The itch app is a desktop client for downloading and running games and software from itch.io. Its built-in browser lets users browse creator pages and install titles, while the library keeps downloads together and updates installed games automatically. Users can access collections, bundles, purchases and installed games in the app. Browser-based games can be synced for offline play, and games using itch.io command-line tools can receive delta patches that download only changed data. The client is available for Windows, macOS and Linux, with Windows 7 or newer required, and it is open source and offered in over 20 languages. Creators can provide an app manifest to define launch targets and integrate with the app API. The app registers itch:// and itchio:// links and can create Steam library shortcuts for installed games. Its sandbox limits file access, isolates home directories for Linux games and runs Windows games as less-privileged users. Compatibility problems can still occur, especially on Linux when games do not follow best practices. The listed plan is free.

Kenney Assets is a downloadable library of game-development materials, including 2D sprites, 3D models, UI elements, audio, fonts, pixel art, and textures. Individual packs are free to download, while the Kenney Game Assets All-in-1 bundle is a one-time purchase at a minimum price of 19.95 USD. The bundle lists more than 60,000 assets, including over 1,200 sound effects and music loops, plus bitmap and vector fonts. Asset packs use a CC0 public-domain license, which permits commercial projects without requiring attribution. Listed formats include PNG, SVG, OBJ, FBX, GLTF, and OGG, described as compatible with all game engines. An optional launcher for Windows and Linux includes tools for tile extraction and combination, converting files and images, PNG compression, audio processing, and store-thumbnail creation. New packs are added frequently, and updates are free for existing bundle owners. Kenney does not support importing assets into specific game engines, directing users instead to its knowledge base or the engine's documentation and community.
