About SingURLs

What SingURLs is

SingURLs is a catalog of discontinued web products — startups, apps, and side projects that once had real users and have since gone dark. We track hundreds of thousands of domains, confirm which ones are genuinely gone (not just slow, redesigned, or temporarily down), and publish them as a searchable, browsable record of what the internet has quietly lost.

For any listed product, our AI advisor can generate an original startup idea inspired by what it validated — never a clone or a revival of the original. Every generation follows an explicit originality policy: it must state how it differs from the product that inspired it.

How we keep it accurate

We continuously track products from across the web and confirm each one is genuinely, permanently gone — not just slow, redesigned, or having a rough week — before it's ever added to the catalog. For every listing, we capture only factual details: what the product did, its category, and its technology. We never store or republish the original site's content itself.

What we are not

SingURLs is not affiliated with, endorsed by, or connected to any product, company, or brand listed in the catalog. Names, logos, and trademarks referenced here belong to their respective (in most cases, former) owners and are used only to factually identify what a listing refers to. See our Terms for the full disclaimer.

If you own or represent a listed product and believe a listing is inaccurate or should be removed, see our Takedown page.
