Yes for Kenney: its assets are public domain (CC0), free to use in commercial games with no credit required. OpenGameArt is a mixed repository – each asset has its own license, so you must check the license on every individual item before shipping.

Yes for Kenney: every asset on kenney.nl is public domain (CC0), and Kenney’s own support page confirms you’re free to use them, even in commercial projects, with attribution not required. OpenGameArt is different – it’s a community-driven library where each upload carries whatever license its creator chose (CC0, CC-BY, CC-BY-SA, or more restrictive terms), so “OpenGameArt” is not itself a license. Check the license line on every individual asset page before shipping it in a paid or ad-monetized web game.

What should you watch for as a browser game developer?
- Kenney’s logo is reserved – the CC0 grant covers the assets themselves, not Kenney’s studio branding.
- Attribution is optional but simple – crediting “Kenney” costs nothing and is welcomed even though not required.
- OpenGameArt mixes CC0 and share-alike items – a CC-BY-SA asset can require you to release derivative art under the same license, which matters if you’re distributing a closed-source web build to multiple portals.
- Terms change – re-check the license page for any asset before a commercial release, especially if you downloaded it long ago.
