itch.io (Adult)

itch.io is the leading indie game marketplace, and its adult section is one of the best places to find original, creator-made 18+ games. Because it is a genuine indie platform, you get everything from polished visual novels and dating sims to experimental and niche titles, often on a pay-what-you-want basis that supports developers directly. The quality ceiling is high — some of the best indie adult games launch here first — and buying means you actually own and support the work rather than feeding a gacha. The trade-off is that it is a sprawling marketplace, so curation is on you and quality varies wildly. But for original, creator-first adult games, itch.io is a top destination.
