14 browser city builder games you can play today

29 July 2026 · Updated 20 October 2026 · Reading time about 17 minutes

Search for a city builder you can play in a browser and you get plenty of results and surprisingly few games. These fourteen really do run in a tab with nothing to install. They are ranked, and the catch in each one is spelled out.

Every game below was live on 20 October 2026, and we played most of them. The table has the whole list at a glance: what each one costs, whether it wants an account, and whether it runs on a phone. After it comes a short guide to the four kinds of online city builder game, then each game in rank order, with what it is actually like and where it will annoy you.

The list at a glance

How to read this list: four kinds of browser city builder

"Browser city builder" describes four quite different kinds of game, and the results pages mix them together. Once you can tell them apart, finding one you will enjoy takes about five minutes.

1. The free-to-play MMOs. Forge of Empires, Elvenar, Grepolis and Ikariam have each been going for more than a decade, and they and their relatives work on build timers: early buildings finish in seconds or minutes, later ones take hours, and premium items for sale shorten the wait. Raiding varies more than the reputation suggests. Elvenar and Rise of Cultures have none, Forge of Empires has a limited daily plunder, and Grepolis, Ikariam, Goodgame Empire, Tentlan, Travian and Tribal Wars are war games with a city attached. All of them want an account, and the tell before you commit is a registration wall, a world to pick, or a countdown on your first building. We set them against real multiplayer city builders in multiplayer city builder games.
2. The portal games. Poki, CrazyGames and GamePix host a great many light, ad-supported games with a building theme, and some of them are idle clickers in a hard hat. Not all: Poki's Village Builder and CrazyGames' City Builder are real, if modest, settlement builders, and The Final Earth 2, top of this list, is on both sites. They need no account, and they are the likeliest games here to run on a phone.
3. itch.io. The part most people miss, and where the real finds are: on 20 October 2026 it listed 1,725 web games tagged City Builder, and 66 of the 72 most popular were free or name-your-own-price. Start from the web city builder tag, sorted by popularity, and judge by what every page shows: a star rating with its count, and a status of Prototype, In development or Released. Beyond The Final Earth 2, try Six-Sided Streets, a hex-tile town puzzle, and Before the Ash, a jam game about growing Pompeii before Vesuvius ends it.
4. Standalone browser games. Complete games that happen to live on a web page, free or sold once, mostly with no account and no build timers: micropolisJS, Freeciv-web, Kittens Game, Evolve, A Dark Room, the Townscaper demo and our own. They fill three of the top seven places below.

The order is our judgement of how good a city builder each game is once it is running, marked down for what it asks of you first: money, an account, or patience with a timer. Our own game is on the list at number three, disclosed where it appears, and you should weigh that placing knowing who wrote it.

A few names you will see elsewhere are missing on purpose. The Settlers Online was the top Google result for "browser city builder" when we checked, but its own help pages ask for a Flash plugin, which modern browsers dropped in 2021, or a Windows client download. Rise of Kingdoms is a mobile game with a PC download, Unciv has no official browser version, SimCity BuildIt is a phone app, and city-builder.online, despite the name, sells printable paper city models.

Online city builder games, ranked

1. The Final Earth 2

Seen side-on, a sci-fi colony grows from a single ship into a towering city. It is one of the best-made free city builders on the web, with an average of 4.7 stars from 518 ratings on its itch.io page, and it asks nothing of you: no account, no payment. That page is also open about the paid edition on Steam, iOS and Android carrying much more content, so treat the browser version as a generous sample of a bigger game.

Price: free in the browser, also on Poki and CrazyGames; the fuller edition is $9.99 on Steam · Account: none · Phone: touch input listed

2. micropolisJS

The 1989 SimCity design as it was: zones, roads, power lines, and disasters that include floods and a monster. Graeme McCutcheon ported it to JavaScript in 2013 from the code Electronic Arts released as open source, which is why it goes by the name Micropolis; the SimCity section below has the story. It looks every one of its years, but micropolisJS is complete and legal, and you are zoning your first neighbourhood a few seconds after the page opens.

Price: free, open source · Account: none · Phone: no, the site says the screen is too small

3. Cities of the Aegean (ours)

Our game, so read this with the appropriate scepticism. It is the only city builder here in the walker tradition of Caesar III and Zeus: Master of Olympus, so the carts and agora vendors of an ancient Greek polis really carry food along the roads you lay, and a district can starve beside a full granary because nobody walks that far. It is marked down for the catch: only the first fifteen minutes are free, and a trial city is not kept unless you buy before you close the tab. The fuller practical details come after the SimCity section.

Price: the first fifteen minutes free, then €4.99 + VAT once · Account: none, an email only if you buy · Saves: none during the trial · Phone: plays turned sideways, best on a desktop

4. Forge of Empires

The browser city builder most people have heard of, run by InnoGames since April 2012, in which you lead a settlement from the Stone Age forward, era by era. Forge of Empires is polished and generous for the first few days, then settles into the timer-game rhythm of waiting, paying or logging in twice a day. Once unlocked, its player-versus-player is milder than its reputation: the Forge of Empires wiki says a neighbour outside your friends and guild can raid you once a day for one finished production, never your Great Buildings. InnoGames' newer, mobile-first Rise of Cultures has had a browser version since 2022 and, its support pages say, no raiding at all.

Price: free-to-play, with build timers and paid premium items · Account: yes · Phone: the browser sends you to the app

5. BuildCity.io

The nearest thing to a modern SimCity in a tab, and a personal project, according to its About page. By its own description you zone, lay roads, run power and water and chase land value in 3D, and tax income keeps arriving for up to a day while you are away. BuildCity.io lets you start a guest city without signing up and says its paid map unlocks and extra city slots are optional. It is small, but nothing else here looks so much like the modern genre.

Price: free, with optional paid map unlocks and city slots · Account: not for a guest city, yes to keep one · Phone: works, it says

6. Elvenar

The calm one among the big MMOs. Since 2015 InnoGames has let you lay out a tidy fantasy city as elves or humans in Elvenar, planned around upgrades and trade with your neighbours, and reviews and player guides agree that nobody can raid it. The construction queue still sets the pace, so it suits someone who likes tending a city in short visits more than someone who wants to sit down and build for an evening.

Price: free-to-play, with build timers and paid premium items · Account: yes · Phone: the browser sends you to the app

7. Freeciv-web

Civilization II-style empire building, free and properly deep: you found cities and take a people from the Stone Age to the Space Age, against the AI or on slow multiplayer worlds where everyone plays one turn a day. Cities matter, but the game is about the empire, which is why it sits mid-table on a city builder list. Freeciv itself dates to 1996, and the community server at freecivweb.com counted about 3.14 million single-player games since 2016 when we looked. Type that address carefully, because the .org version is now a gambling site.

Price: free, open source · Account: only if you want to save · Phone: not tested

8. Kittens Game

A village of cats, told entirely in text, that slowly becomes a spacefaring civilisation. There is nothing to look at and everything to count, and the economy underneath is deep, demanding and still being updated years on. The web version stays free, though a paid edition arrived on Steam in February 2026. If it hooks you, Evolve, which grows from protoplasm into a full city economy, and A Dark Room, where a fire becomes a village, are the next two in the same family.

Price: free on the web, paid on Steam and in the apps · Account: none · Phone: poorly, it shows the desktop layout

9. Ikariam

Greek island towns in an older, gentler-looking MMO that Gameforge has run since 2008. Trade and research matter in Ikariam as much as fleets, which makes it the most economy-minded of the war MMOs, but it is a timer game underneath and other players can attack you. The lobby wants an email address, or a Facebook or Google sign-up, before you see anything.

Price: free-to-play with build timers · Account: yes, a Gameforge one · Phone: unclear; Gameforge says it plays on phones without saying whether that means the browser

10. City Builder (CrazyGames)

The meatiest of the portal games here. You lay out a small town in a valley and its residents go out to gather wood, stone and wheat for you, which gives it more substance than most portal games, though it stays light and carries adverts. City Builder comes from Dorfer Games, and CrazyGames says it runs in phone and tablet browsers as well as on a desktop.

Price: free, with adverts · Account: none · Phone: yes, CrazyGames says

11. Townscaper (web demo)

Barely a city builder, and on the list anyway. Click on open water and a little harbour town assembles itself; there are no goals and no economy, and it is the most pleasant ten minutes on this page. Oskar Stålberg's web demo is free, and the full game is $5.99 on Steam.

Price: free demo of a paid game · Account: none · Phone: not tested

12. Grepolis

Ancient Greece and its gods, run by InnoGames since 2009, and the obvious one to try if you came here from Zeus: Master of Olympus. Know what it is first: in Grepolis your polis is mostly a barracks with a temple attached, the gods act as spell-casters, and the real game is alliance warfare on a shared map, played in short daily check-ins. We set it beside the other Greek myth games in our Greek mythology games guide.

Price: free-to-play, with build timers and paid premium items · Account: yes · Phone: not tested; apps exist

13. Village Builder (Poki)

A light place-and-upgrade settlement game by Project GD, made for short sessions. Poki shows Village Builder rated 4.2 from about 59,000 votes and lists it for phones and tablets as well as desktops. Simple, with adverts, and fine for a coffee break.

Price: free, with adverts · Account: none · Phone: yes, Poki says

14. SuperCity

A friendly survivor of the Facebook era: Playkot launched it in 2011 and says it has passed 40 million installs. You build and decorate a modern metropolis through quests and collections, and it cares more about skylines than simulation. Play now on its site goes straight to a login box (email, Facebook, Google or Microsoft), and the site lists tablets but not phones.

Price: free-to-play, with paid items · Account: yes · Phone: tablets, its site says; phones unclear

Can you play SimCity in a browser?

Yes, legally and for free, though not under that name. In January 2008 Electronic Arts released the source code of the original 1989 SimCity as free software under the GPL, prompted by the One Laptop Per Child project, with Don Hopkins doing the work. EA kept the SimCity trademark, so the open code went out under the game's old working title, Micropolis. Only versions that pass EA's own quality checks may use the SimCity name, which is how the build on the OLPC laptops kept it.

Two browser versions of that code run today:

• micropolisJS, the complete game in a desktop browser with no account, and number two on our list.
• MicropolisWeb, Don Hopkins' own WebAssembly build. Its site calls it unfinished, and for now it is a demo to poke at: keys load cities and change the speed and the tax rate.

Neither is official SimCity, and the Micropolis name is itself a registered trademark, now held by Micropolis GmbH, which licenses it to both projects.

There is no official browser SimCity today. Wikipedia records that Maxis put a browser version of SimCity Classic online in 2008 and that a later one ran as Micropolis Online; neither loads any more. SimCity BuildIt is a phone app with no browser version.

The old DOS versions are a greyer matter. The Internet Archive streams the 1989 SimCity and SimCity 2000 in an in-browser emulator, and both started when we tried them in October 2026, but nothing on those pages shows a licence from EA. Treat them as unofficial preservation copies that may disappear, which is why we are not linking them, and the same goes for the abandonware sites that rank for "SimCity browser game". If it is SimCity 2000 you want, EA still sells SimCity 2000 Special Edition on GOG: a download, but the legal way to play it.

Cities of the Aegean, in more detail

This one is ours, so weigh it accordingly.

We built it in the style of the Impressions city builders of 1998 to 2000, Caesar III and Zeus in particular. You found a polis on an Aegean island or coast and lay roads, and the simulation runs on walkers: farm carts hauling wheat to granaries, agora vendors carrying food out to the houses they pass, rival cities' caravans calling to trade. Houses climb from huts to great estates as water, food, olive oil and fleece reach them, and fall back down when a supply chain breaks. Around that runs a four-season year in which summer is the dead season, six rival cities that trade, feud and conquer each other on an Aegean map, and temples to eight Olympians, every one of whom walks your streets once their temple is finished and staffed. If Zeus is where you are coming from, our Zeus: Master of Olympus guide covers playing the original today and where ours sits beside it.

Practical details, since this article is about how these games work rather than how they feel:

• No account or registration to start. You give an email address only if you buy, and the licence is tied to it, so you can restore it on any device.
• No build timers. The city simulates in your tab, and three speed settings run it at up to five times normal pace; the only clock is the fifteen free minutes.
• Saving belongs to the licence. A trial city is not kept unless you buy before you close the tab, in which case it carries straight on. Licensed cities autosave every game month, sync to the cloud and can be downloaded as a file.
• Some of it is online. Licensed players can take on another player in Rival Archons, an asynchronous one-against-one match started from an invite code, enter the weekly Games of Delos challenge, and hang a city in the Hall of Cities, a gallery anyone can tour.
• The price: the first fifteen minutes are free, tutorial included, and the whole game (the story, the sandbox and saved cities) is €4.99 plus VAT, paid once.
• The title screen is there as soon as the page opens and the city's art streams in behind it. It plays best on a desktop or laptop, and on a phone turned sideways.

What you are buying, if you buy it, is a game rather than a subscription, and there is nothing else to sell you afterwards. If you want to see how it plays before you start, the beginner's guide walks through the opening build order.

Questions people ask

Are there free city builders you can play online?

Plenty, if you mean free with no catch beyond age or size: The Final Earth 2, micropolisJS, Freeciv-web, Kittens Game and the Townscaper demo all cost nothing and need no account to play. Forge of Empires, Elvenar and Grepolis are free to start but run on build timers and sell premium items. Our free city builder games guide covers the free options you can install, too.

Can you play city building games online without downloading anything?

Yes. Every game on this list runs in a browser tab with nothing to install, and micropolisJS, The Final Earth 2 and the portal games do not even ask for an account. The catch is on phones, where Forge of Empires and Elvenar send you to their apps instead. The Settlers Online, often listed as a browser game, still needs a Flash plugin or a Windows client.

Is there a 3D city builder you can play in a browser?

BuildCity.io is the one to try. It is a 3D city builder made with Three.js, with zoning, utilities and land value by its own description, and you can start a guest city without signing up. The Townscaper web demo is 3D too, though it is a toy town with no goals. Ours, for the record, is isometric 2D in the Impressions style.

Can you play SimCity 2000 online?

Not officially: there is no licensed browser version. The Internet Archive streams the DOS original in an in-browser emulator, but nothing there shows a licence from EA, so treat it as an unofficial copy that may vanish. EA still sells SimCity 2000 Special Edition on GOG as a download. The legal free route in a tab is the 1989 game, through micropolisJS.

Which browser city builders work on an Android phone?

Fewer than you would hope. The Final Earth 2 lists touch input, Poki and CrazyGames say Village Builder and City Builder run in phone browsers, and BuildCity.io says it works on phones. Forge of Empires, Elvenar and Rise of Cultures send a phone browser to the Google Play app, and micropolisJS turns small screens away. Ours plays on a phone turned sideways, though a desktop suits it better.

Where to start

If you want one link, make it The Final Earth 2. If you want SimCity, micropolisJS is the real thing under another name. If you want a city to tend for months in ten-minute visits, Forge of Empires or Elvenar will take them gladly. If you want the walker city of Caesar III and Zeus without installing anything, that is ours, disclosure and all. And if you can install something after all, the heavyweights are in the best city builder games of 2026.
