Basement is now a shopping browser. Today we launch agentic checkout: your AI shopper finds the best price across the web and buys it for you. Every purchase runs on a single-use card scoped to one order, so your real card is never exposed and nothing goes beyond the budget you set. Every payment lands in one place. Powered by Crossmint. It knows what you like. Now it can buy it. Live on iOS and Chrome.
Hey Product Hunt, Luis here, founder of Basement.
I have spent the last decade building consumer products, and this is the one I could not stop thinking about. Shopping online still works against you: your purchases are scattered across dozens of store logins, every tool works for the store, and nothing remembers what you already bought.
So I built a browser whose job is shopping. It learns what you like from how you actually browse, keeps a Closet of everything you own, finds the best price across the web, and today it closes the loop and checks out for you.
The part I am most proud of is how the buying works. Every purchase runs on a single-use card scoped to that one order, minted inside a budget you sign with your passkey. Your real card never touches Basement, and no purchase can go beyond the cap you set. That checkout layer is powered by Crossmint.
It is live today on iOS and Chrome. I would love your feedback, and I will be here all day answering everything.
the single-use card scoped to one order is the part that actually makes this feel usable, that's the real blocker for most people handing over checkout to an agent, not the price comparison. signing the budget with a passkey instead of just a stored limit somewhere is a nice touch too. does the Closet also track price drops on stuff you already own, like if a jacket you bought last month goes on sale somewhere else
the single-use card scoped to one order is a genuinely good answer to the "what if it overspends" worry, but it doesn't cover the "what if it buys the wrong thing" worry. wrong size, wrong color, a near-identical listing from a sketchy third-party seller instead of the actual brand, out of stock item substituted with something else entirely. is there a confirmation step before the card actually gets charged, or does "buys it for you" mean the purchase completes autonomously and you find out what you got when it arrives?
If it can find Argentina vs Spain under $150, I WANT IT RIGHT NOW
How does live chat feature work?

Who hunted Basement?
Basement was hunted by Luis Perrone. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
