The short answer
Allworld and LifeSim are free life sims that run in a browser and use real cities. Allworld is a multiplayer world in early beta, with 3D miniature cities, labelled AI characters beside real players, and open-source code. LifeSim is single player, on a real 3D map of Earth, and every person there is an AI character who remembers you.
What is Allworld?
Allworld is a free browser game at joinallworld.com. Its site calls it “a digital world you can live in.” You make a character, pick a real city, and walk its places in 3D. You can work, rent or build a home, make friends, talk by voice, play games, and vote for your local government. You travel between cities by road, train, or plane.
Its about page says it was inspired by life in Lagos. In October 2026 it listed 284 open cities in 242 countries. Nigerian cities and fifteen other African cities have real places. Every other city starts with a set of game places.
People and AI characters share the world, and every AI character is labelled. The game is in early beta, and its code is public under the AGPL license.
What is LifeSim?
LifeSim is our game. It is a free life sim you play in the browser at play.lifesim.com, or in the iPhone app. You live one life in any real city on a 3D map of Earth. Every person in the city is an AI character with a job, a home, friends, a routine, and a memory of you. You talk to them in your own words.
We make LifeSim, so read this page with that in mind. We only state facts about Allworld that its own pages state, and we link each one below.

Where Allworld is stronger
Real people. Allworld is a shared world. You can hang out with friends, call them by voice, and play chess, Whot, or Ayo with them. LifeSim has no other players.
A city to run. Allworld has local elections, shops for real businesses, events, and a feed. LifeSim has no elections and no shops for real businesses.
Open code. Anyone can read Allworld’s code, run a copy, or add a game. You can also connect your own AI agent, such as ChatGPT or Claude, to play a character.
African cities. Lagos and the other Nigerian cities have real, sourced places, and the game knows the danfo, the okada, and the keke.
Where LifeSim is stronger
The real map. LifeSim puts you on a real 3D map of Earth, with real streets and places. You can search for a café and walk to it. Allworld’s README says its city maps are written in code and its roads are stylised.
A whole city of people. In LifeSim every person is an AI character with a routine for weekdays and weekends. They text you first, gossip, and remember what you did. Allworld’s features page says that a few AI residents live in each city.
Talk in your own words. LifeSim has no dialogue trees. You type what you would say, and the person answers from their memories and plans. Allworld’s features page lists a daily limit on private chats and calls with AI characters.
No money at all. LifeSim has nothing to buy and nothing to sell. Allworld has no paid game money, but it has real-money features for businesses and event hosts.
Your first week in LifeSim
You pick a city. Any city, on a real map of Earth. You give your character a name and a reason to be there. Then you step out onto a real street, and there are people on it.
They’re not waiting for you. They have jobs to get to, homes to go back to, friends they see on Fridays. Say hi to one of them, in your own words, and they answer in theirs. Tell them something and they keep it. Tell their friend something and it gets around.
By the end of the week you have a place you go in the mornings, someone you’re avoiding, and someone you’re not. One player once stayed for thirteen hours straight. We checked.
LifeSim is a free game, in the browser and on iPhone. No ads and nothing to buy. Season 1 is in beta.
What we could not check
The IndieDB page of Allworld did not load for us, so we used Allworld’s own site and its GitHub page. Allworld’s site does not name a company. We found no press coverage of it and no player numbers.
We did not test how well Allworld’s AI characters remember you. We report what its pages say. Allworld changes fast: its GitHub repository was created on October 4, 2026. Check its site for the latest.
Which one should you play?
Play Allworld if you want a world to share with friends, or a game set in Lagos or another African city. Play LifeSim if you want to live alone in a real city, any city, and have every person there answer you and remember you.
Both are free and run in the browser, so you can try both tonight. For more games like these, read AI life simulator games and life sims you can play in your browser.
