Kenney is the closest thing game dev has to a universal parts bin. One site, thousands of assets - 2D characters, tilesets, UI packs, low-poly 3D models, audio jingles - all released into the public domain (CC0) with no attribution required. When an idea needs visuals today, this is the first stop.
Where it shines
- Zero legal friction. CC0 means you can ship a commercial game with these assets and owe nobody anything - no credits screen, no license file, no lawyer.
- Consistent art direction. Each pack is drawn as a set, so a whole platformer or puzzle game looks coherent instead of stitched together from five styles.
- Prototype velocity. Grab a UI kit, a character set and a tilemap and you have an art pipeline in ten minutes - perfect for game jams and AI-generated demos that need real visuals fast.
Where it falls short
- The style is recognizable; if your game must look unique, Kenney gets you to a playable build, not to a final look.
- Catalog is curated by one person, so niche themes (historical, horror, realistic) are thin.
The real cost
Free, no account, no paywall - donations accepted. The only “cost” is that players may spot the same assets in other indie games.
Verdict
The default asset library for anything that needs to be playable before it needs to be pretty. Keep the URL in your bookmarks bar, not your memory.
