Ouch! is Icons8's illustration arm: not one style but over 300 curated style collections contributed across dozens of artists, spanning hand-drawn, 3D, isometric, and flat approaches.
Because it spans so many artists and styles, it works more like a search engine for illustration aesthetics than one cohesive set: useful when you're not sure which look you want yet.
Good for exploring very different visual directions before committing, rather than for a team that already knows its exact style and needs depth within it.
Licensing is genuinely mixed: some styles carry a "Free" badge and others sit behind an Icons8 subscription, so it's worth checking each style individually instead of assuming the whole library is free.
Free vector illustrations to bring some personality to your project.
