A hosted WorkAdventure alternative with live build mode and games
Flat.social is a browser-based spatial workspace with nothing to host: walk up to people and talk, play games that run inside the room, and build the map live from inside it. Free for 5 people, $6 per seat after that. Watch the demo, then see how it compares with WorkAdventure on pricing and the basics.
Free up to 5 people, no credit card required
WorkAdventure is the open-source option in spatial collaboration: a 16-bit pixel-art world with proximity audio that runs in every major browser, maps built in the Tiled editor, a hosted plan, and code under AGPL v3 with a Commons Clause so an organisation can run the whole stack on its own servers. If you are searching for a WorkAdventure alternative, this page shows what Flat.social does and puts the two side by side on pricing and the basics.
Flat.social is a hosted spatial workspace with nothing to run: a virtual office your team walks around with proximity audio, plus team socials and events in the same space. Built-in games run on a physics engine, you build the map live from inside the room, and a conference-grid room type covers all-hands and presentations. Free for up to 5 people at once with no time limit, $6 per seat per month after that up to 100 people, and a $2 per seat Day Pass for one-off events. It runs in the browser, nothing to install, and guests join from a link without creating an account. Full details on the pricing page.
Is Flat.social a good WorkAdventure alternative?
Flat.social is a hosted spatial workspace built on the same idea as WorkAdventure: walk your avatar up to someone and talk, with voices that fade with distance, and visitors who join without signing up. It adds built-in games on a physics engine, a build mode you use live from inside the room, a conference-grid room type and timed speed networking, with no servers to run. It is free for up to 5 people at once with no time limit and $6 per concurrent seat per month above that.
How does Flat.social pricing compare with WorkAdventure?
Both bill on concurrent users. As of September 2026 WorkAdventure's hosted plan is free for up to 10 concurrent users, then Business from €8 per user per month, with an Event plan from €4 per user per day; self-hosting has no licence fee. Flat.social is free for 5 people at once, then $6 per concurrent seat per month from 6 to 100 seats, plus a $2 per seat Day Pass. Twenty-five seats for a month is from €200 on WorkAdventure hosted and $150 on Flat.social.
Walk up and talk, with nothing to keep running
Proximity audio works the way it does in WorkAdventure: voices fade in as you approach and fade out as you leave, so groups form and dissolve without anyone pressing a button. The world around it is a low-poly 3D space with a physics engine underneath, and it is hosted for you.

Pricing at a glance: WorkAdventure vs Flat.social
WorkAdventure's hosted plan bills on concurrent users per map, the same basis as Flat.social: you pay for how many people can be in the space at once, not for headcount. Self-hosting has no licence fee; you pay for servers and for someone's time. WorkAdventure publishes its prices in euros, shown here as published. List prices as of September 2026.
A 25-person team, one month
- WorkAdventure hosted: 25 concurrent users × €8 = from €200
- WorkAdventure self-hosted: €0 licence, plus your servers and the hours to run them
- Flat.social: 25 seats × $6 = $150
A 60-person company where about 20 people are online at the same time
- WorkAdventure hosted: 20 concurrent users × €8 = from €160
- Flat.social: 20 seats × $6 = $120
A one-off event for 100 people
- WorkAdventure: Event plan from €4 per user per day = from €400 for the day
- Flat.social: 100 seats × $2 Day Pass = $200, valid 24 hours, cancel free until the day before
Trying it out
- WorkAdventure: hosted plan free for up to 10 concurrent users
- Flat.social: free for 5 people at once, no time limit
Both sets of figures can change. Current Flat.social plans are on the pricing page.
Free: up to 5 people in your flat at once. Monthly: $6 per seat per month, from 6 to 100 seats. Day Pass: $2 per seat for a one-off event. A seat is one concurrent spot, not a named user, and every room holds up to 100 people. See pricing and plans & limits.
Build the office from inside it
In Flat.social you open build mode while the team is in the room and drag in a standup corner, a whiteboard wall and a football pitch. Change your mind on Friday, fix it in a minute, nothing to upload or redeploy. Your own maps and look are included on the free plan.
Coming from WorkAdventure? Set up Flat.social in an afternoon
Most teams pick a template, shape it in build mode and run their first standup the same day.
- 1Create a free workspace
Sign up with Google or email and name your space. The free plan covers 5 people at once with no time limit, so you can try it properly before paying anything.
- 2Pick a map and shape it
Start from a template, then open build mode and drag in what you use: a standup corner, a couple of desk clusters, a lounge with a football pitch or a poker table, a whiteboard wall. Keep it compact; a snug office feels busier than a sprawling one.
- 3Set roles
Decide who can build, who can moderate, and what guests can do. Roles and access controls are on the Monthly plan; on Free everyone can walk around and talk.
- 4Share one link
Pin the room link in Slack or Teams. Teammates open it in a browser. Guests type a name and join without an account. Nobody installs anything.
- 5Run the first real thing today
A standup, a Friday social, a speed-networking round for new hires. The habit forms around the first useful session, not the perfect layout.
Games that run inside the room
A football pitch with a live scoreboard, a poker table, chess and dice sit in the map itself, on a physics engine, so the ball rolls and the dice tumble. The Friday social happens in the same space as the Monday standup, with nothing to share or install.
