The hashtag website is hashtag.org. Its web3 side, the on-chain registry, lives at hashtag.space. If you searched “website hashtag” or typed www.hashtag into your browser expecting a real page, this is the place you were trying to reach.
People arrive here a dozen different ways. Some type the words in the wrong order, some drop the TLD, and some search in another language. They all mean the same thing: the site where the hashtag is the whole point. You can claim a #Name, put a pin on a searchable map, and let an AI agent answer for you while you sleep. We’ll get to all of that. First, the addresses.
“www.hashtag,” “site hashtag,” and other ways people find us
Search engines see this one a lot: “website hashtag,” “site hashtag,” “hashtag site.” In Spanish and Portuguese it shows up as “site de hashtag” and “site de hashtags,” which just means hashtag site. Different words, same destination. Whatever phrasing got you here, the answer is hashtag.org.
One small snag worth clearing up: www.hashtag on its own isn’t a valid web address. A browser needs a TLD, the .org or .com part at the end, before it knows where to go. So typing www.hashtag and hitting enter usually drops you into a search results page instead of a site. The real address is hashtag.org. Type that and you land exactly where you meant to.
What the # symbol is actually called
Since you’re here, let’s settle the trivia. The formal name for the # symbol is the octothorpe. Almost nobody says that out loud, so it goes by several everyday names too: the hash, the pound sign, the number sign, and in music the sharp. Same character, different rooms of the house.
A “hashtag” is technically the word you put after the symbol. So #coffee is a hashtag; the # by itself is the octothorpe. On social media the two blurred together until most people call the whole thing a hashtag, and that’s fine. But if a crossword or a curious kid ever asks what the # is called, octothorpe is the answer that wins the point.
What you can do on the hashtag website
hashtag.org isn’t a dictionary page about symbols. It’s a working platform. Here’s what you actually do once you’re inside:
- Claim a #Name. Register your name, your brand, or a place as a hashtag you own instead of one anyone can borrow.
- Get a GEO portal on the map. Your #Name becomes a pin on the spatial web, findable by location, not just by keyword.
- Let GIGI answer. GIGI is an AI agent that greets visitors to your portal, answers questions, and handles the conversation when you’re not around.
- Browse and trade. Explore the map to see who’s where, and buy or sell names on the marketplace.
hashtag.org vs hashtag.space
You’ll see both addresses, and they aren’t the same thing. hashtag.org is the everyday front door: the map, your portal, GIGI, the marketplace, all the web2 things you interact with in a normal browser. hashtag.space is the #SPACE on-chain registry, the web3 layer where a #Name is recorded as something you truly hold rather than something a platform lends you.
Most people never need to think about the registry to use the site. It runs underneath, keeping ownership honest. If you want the full picture of how the pieces fit, read How hashtag.org works.
