The Hidden Wiki
The Hidden Wiki is a collection of .onion link indexes that anyone can edit. That makes it useful, unreliable and sometimes dangerous. Here's how to use it safely — and what to use instead.
The Hidden Wiki is one of the oldest and best-known link directories on the Tor network. It's a wiki — in the original sense of the word — listing .onion addresses across categories like email, search, news, forums and, notoriously, a lot of things that shouldn't be clicked.
If you've googled "hidden wiki" you've probably seen dozens of sites claiming to be the real one. They mostly aren't.
A brief history
The original Hidden Wiki appeared in 2007 on an older v2 onion address and quickly became the default jumping-off point for new Tor users. It was taken down, forked, replaced, defaced and resurrected multiple times over the following decade. By the time the Tor network retired v2 onion addresses in 2021, dozens of "Hidden Wiki" mirrors existed simultaneously, each with its own editor and its own agenda.
Today, any .onion address calling itself "the Hidden Wiki" is, in practice, just a link index maintained by whoever controls that server.
Why it exists
Search engines index .onion services unevenly — see our guide on dark web search engines — and many services don't advertise themselves on the clearnet at all. A human-edited directory fills that gap. Hidden Wiki clones organise services by topic, include short descriptions, and give beginners somewhere to start.
Why you shouldn't trust it blindly
The openness that makes a wiki useful also makes it dangerous:
- Phishing mirrors. A common attack is to clone a legitimate service's design and get its fake address added to a popular wiki. Users who paste credentials lose them.
- Scam markets. Several "marketplaces" listed on Hidden Wiki clones are exit scams designed to steal cryptocurrency on deposit.
- Illegal content. Some clones include links to material that is illegal in essentially every jurisdiction. Clicking on them, by accident or otherwise, can get you into real trouble.
- Dead links. Onion services change addresses regularly. A wiki maintained sporadically is full of stale entries that have quietly been taken over by new operators.
How to tell a good onion index from a bad one
Some practical heuristics:
- Does the directory only list services whose onion address is publicly advertised by the service itself? That's the gold standard for verification.
- Does it flag which entries are official mirrors versus third-party copies?
- Does it keep a visible changelog or last-updated timestamp?
- Is it transparent about who maintains it? Anonymous is fine; untraceable-and-profit-motivated is not.
If the answer to most of these is "no," treat every entry as unverified and cross-check any address with the organisation's clearnet site before using it.
Using it safely, if you still want to
- Keep the Tor Browser's default security settings. Don't lower them to "Standard" on unknown wikis.
- Never paste real credentials into a site you reached through a wiki.
- If a service asks for cryptocurrency up front, treat it as a scam until proven otherwise.
- If a link ends in the old short 16-character
.onionformat, the link is dead (and possibly hijacked). v3 addresses are 56 characters.
A better starting point
If you came here looking for a Hidden Wiki because you wanted a launchpad, you've got two much safer options than a random wiki clone:
- Deepr — a dark web search engine and community-driven link directory in one. Search anything across the Tor network, browse by category, vote on listings, and see each service's live status and stability history. It's the closest thing to a modern, self-correcting Hidden Wiki and it's where most people should start.
- dark.cfd — a hand-curated directory that only lists well-known, publicly-advertised services from real organisations. A much shorter list, on purpose.
