Play
Kick a ball, run a parkour route, fight a match, sit down to a board game, pull espresso in the café, or just tend the garden. It’s all built already. You just walk in.

👾 Closed beta — come in, it’s open
Not here to chat <3 here to play.
The fastest way to hang out online. A virtual arcade for your crew, game jam, or community. Zero downloads — just drop a link and jump straight into the action in seconds.
Up to 12 people per space, and guests on a link aren’t members. Two of you at 3am counts.
Enjoy
Play. Create. Share.
That’s the whole thing, roughly in the order you’ll meet it.
Create
The room you are standing in is the editor. Place blocks while people are standing on them, move the goalposts, and save it. With xp, you can build a whole game with its own rules.

Share
Send an invite link that expires when you say. Publish a world so strangers can play it, or keep it private for your crew. Make a film of your space and send it anywhere.

Run it yourself
kxb has a community edition: the same world, as a public repository on GitHub. Host it on your own server, read how it is built, or write a country guide for the handbook. The €20 buys you not having to.
The icebreaker
10 strangers, one ball, no name tags
Nobody wants to introduce themselves in a circle. Lay a pitch instead. The game starts the moment the second person walks in, one browser owns the ball so nobody plays against the lag, and nothing anywhere keeps a ranking. By half time they’ve got something to talk about.
Football, battles and races →
The closing party
The bit everyone actually remembers
Lay the club, put a track on, flip the room into party mode. Everybody in it lights the place up in their own colour, the rig sweeps the floor, and whoever started it gets the rainbow. It’s a broadcast, not a setting — when it stops, there’s nothing to clean up.
What’s in the lounge →
Building
The room is the level editor
There is no separate build mode to go to. Fifty-eight pieces in the palette, and you place them standing in the world with everyone else still standing in it. Put the goalposts down and it’s a pitch. Save it, and it’s an arena you can drop into any space you own.
How building works →
Doors open
One link, and they’re already inside
Put the door in the calendar invite, the Discord announcement, the group chat. Whoever opens it types a name, picks one of twenty-four animals, and walks in. Nothing to accept, nothing to install, no password to invent. Set it to knock first if you’d rather be asked.
Links, rooms and members →New in the room
There’s furniture in it now, and some of it drives
A block is ground. Cell (3, 0, 7) is dirt, and that is the whole of what there is to know about it — it cannot fall, it cannot be yours, and it cannot be a fountain. What was missing was everything that stands on the ground. Type a word into the chat box and it turns up in front of you, out of 5,770 models.

Give it rules, states and a recipe
Four things can happen to a thing and eight things it can do about them, set in a panel while you stand next to it. Then it can become something else — raw, cooking, cooked, burnt — and the recipe for that lives on the table it is made at rather than in a book somewhere. Give it an engine and a seat and somebody drives it away.
How a thing is made →And you can say something out loud
Hold a key and talk: your voice comes out of where you are standing, full volume up close and gone by the far wall, so one room holds as many conversations as it has corners. Switch your camera on and your face is a disc over your animal’s head. Type instead if you would rather. None of it is a call — nobody sends an invite, and nothing ends when the host leaves.
The three ways to talk →Inside
And this is what it looks like when it’s yours
Four captures of the running thing: the room you walk around in, a game with a clock on it and a door into it, the page you post on between visits, and the studio for making a film of the place to send to whoever wasn’t there.
The room
It’s one page, and the room is in it
No launcher, no second window, nothing to install. Down the left are the places you can walk into, in the middle you are standing in one of them, and down the right is whoever else is. The switch in the corner turns the same room into a battle and back again. Put a record on and the radio plays into the room rather than into your headphones — so walking in is how you hear it.
What there is to do →
A game, and a door into it
Hand somebody the link and they’re on the start line
A level is a room with a clock. Two people at the line is enough to start, and nothing eliminates you — the person in last place is still running at the end, which is the whole reason anybody finishes. The rail on the right makes a door into exactly this one: a link, or a code somebody points a phone at. No account, no install, no password to invent.
Links, rooms and members →
The space
A board, the places, and whoever is around
Somebody posts the clip of the goal. Somebody says the radio is on all afternoon and they are ignoring most of the requests. Somebody left a crate in the middle of the lounge again. Down the left are the places you can walk into, down the right is who is in them — and the radio plays into the rooms rather than into your headphones, so walking into one is how you hear it.
Rooms, members and links →
The studio
Give the cast a timeline, then press record
One row per animal, one for the camera, one for every block on the set. Scrub to a second and walk somebody across the floor, and it writes the walk that arrives exactly there. Hand them a line and they say it. What comes out is a film of your own space, with your own cast in it.
What the studio makes →
The four controls sitting on that picture. Press one.
Click a spot on the ground, and it writes the walk that gets them there by the second the playhead is parked on. No numbers to type and no path to draw.
Drive them yourself with WASD while the clock runs. Whatever they did is kept as a take — including the bit where you overshot and had to come back.
The camera is riding the shot’s own keys. Let go of it and you can orbit the scene to look at something without moving a single one of them.
Frame it by eye, then save that framing as a camera key where the playhead is. The diamond that appears on the camera row is the one you just made.
People in the world
A space is a link, not a room in a building
Two colleagues at one table or six across three time zones walk into the same lounge the same way, and nobody installs anything. You see the others move as they move, and nobody types, they pull a face and you see it over their head.
The plan, out loud
A linkable web of 3D worlds
xonow
A lightweight multiplayer arcade. Games, a lounge, and VR. Join from a bare link in five seconds, without an account.
xpsoon
The evolution. A web-based multiplayer creator for scenes that run on desktop, mobile, VR, and anything else with a screen. Even your fridge.
The Open Runtimeplanned
The web’s superpower is linking. We plan to open-source the runtime and the adapters, so you can build your own spaces in whatever framework you already like.
That’s the end goal: worlds you can link to the way you link to a page. We are at the very start of it, and this is the part where you get to shape it.
And yes, it costs something
Making a space is free. Keeping one isn’t.
You can make a space and look around it without paying anything — it just stays read-only until it has a plan. Joining somebody else’s space is always free, forever, for everyone.

Three steps and you’re in
01
Walk into the arcade.
The demo is a real space, open right now, with nothing to sign. Fight the greeters — Mo and Suri take it well. Take as long as you like.
02
Join the beta.
Use the code below once you’re in, and the first month is on us.
THEMOMENT2026
03
Send the link.
Bring somebody. It’s not much of an arcade on your own.
Questions? Fair enough.
Do my friends need an account?
No, and they never will. A guest opens the link, types a name, picks an animal and is standing in the room. No email is asked for at the door, because the room doesn’t need one — it needs something to write on their nameplate.
Do I have to install anything?
No. It’s a browser. Desktop, phone, tablet, headset.
What happens if I stop paying?
Nothing is closed. Every space, page and block stays exactly where it is and stays readable forever — only writing stops, and resuming brings it straight back with no migration and no restore step. That isn’t generosity: it falls out of an append-only log, where there is no delete to undo. The room your event happened in is still standing next year.
How many people fit?
Rooms have their own caps, and when one fills up new arrivals are routed to the emptiest room instead of being bounced. Guests on a link sit on top of your member count.
Is there VR?
Yes, in xo today — the lounge is walkable in a headset. The xp side gets it soon, and that one is said out loud on the Create page rather than buried here.
Can I run a conference, jam or party on it?
Yes, and we’ll build the venue to your brief before the doors open. That’s the €200 one — tell us about it and we’ll quote it.
Is it finished?
No. It’s a closed beta and there are things on this page marked soon because they are. Every page on this site has a “what it doesn’t do yet” section, and they are the sections worth reading.
Come and play. Bring somebody.
We’re just starting the closed beta and honestly, I’m happy to finally show it to anyone. Walk into the arcade first — it costs nothing and asks nothing. If you like it, join, and help me shape where it goes next.
