Monstro City closed its doors in December 2019, and if you've been searching for a Moshi Monsters alternative ever since, you're in good company. Here's the honest shortlist — and our pick, Petropolis Play, doesn't ask you to take anyone's word for anything: it's free, runs in your browser with no download, works beautifully on phones, and is embedded on this very page.
Free forever · No download · No account · Progress saves on your own device.
Every "games like Moshi Monsters" search asks you to trust a list. This one embeds its top pick instead — the complete free version of Petropolis Play, live below. Adopt and name your first pet in under 60 seconds, no account needed.
Waking up your pets…

Yes, it's our list and yes, we put ourselves first — so we've printed the yardstick below every pick. Check our work.
Best for: the Moshi feeling — free, in any browser, no download
Full disclosure: this is our game, and it's why this list exists. Petropolis Play shares Moshi Monsters' cozy core. You adopt a pet and name it (ten species, from puppy to one very small dragon). You care for it: hunger, happiness and health tick down gently, and feeding, playing and resting bring them back up. You decorate: drag-and-drop furniture into a room that's entirely yours, across five themes. You collect: 44 shop items, outfits to dress your pet in, more pets to adopt. And the economy works like Monstro City's, minus the membership: PawCoins are earned in minigames and a daily login bonus, and can never be bought. It's free forever with no download and no account wall, it's genuinely mobile-friendly, and your progress saves on your own device — not on a server that can be switched off. The only purchase is an optional $4.99 one-time Full Version — never a subscription. Don't take our word for it: it's embedded above.
Best for: a free pet world in a plain browser tab
The one pet universe from Moshi's era that's still standing: Neopets launched in 1999, outlived Flash, and is still online, still free, and still runs in a real browser tab — no download, no launcher. It goes bigger than Moshi in some directions: multiple pets per account, a deep item economy, dailies, guilds and hundreds of games. The honest catches: it's a quarter-century of accumulated interface, its economy and battling sides are more spreadsheet than snuggle, and optional paid extras sit alongside the free core. If what you miss is a whole world to get lost in, this is the closest living relative.
Best for: the plush-toy adoption ritual
Ganz still operates Webkinz Classic, the 2000s pet-adoption icon: adopt a pet, feed it, play with it, and decorate its room — the same loop Moshi fans grew up on. The honest catches: the traditional adoption model is tied to buying a physical plush toy with an adoption code, it runs through apps rather than a browser tab, and an optional Deluxe Membership gates extras. If you grew up with the plushies too, nothing else is the real thing.
Best for: an officially supported animal world
WildWorks' Animal Jam lets you play as a customizable animal, decorate a den, play minigames and explore a bright, kid-safe world — the closest thing to Monstro City's 'a place to hang out' energy that's still actively supported. It's free to start with an optional membership. The honest catches: the best items sit behind the membership, it's built for kids first, and it's an app install (or the downloadable Animal Jam Classic), not a link you can tap.
Best for: the deep-cut browser original
Marapets has been online since 2004 — one of the few pet sites from Moshi's era still running today, and genuinely free: virtual pets, restocking shops, quests, minigames and collections, all in a plain browser tab. The honest catches: the interface is proudly old-school, there's a lot of it to learn, and the community is smaller than the giants. If you want the authentic 2000s pet-site experience — rough edges included — it's still here.
Best for: the pocket-sized care loop
Zakeh's Pou took the virtual-pet idea mobile back in 2012 and never left: feed your little alien, clean it, play minigames with it, level up and unlock wallpapers and outfits. The honest catches: it's a phone app rather than a browser tab, there's no world to explore or room to decorate, and it's a simpler, quieter loop — closer to a Tamagotchi than to Monstro City. Lovely for a five-minute check-in.
Whatever you try from this list, these are the four things that made Moshi Monsters special — and the four things we checked for.
Moshi Monsters' magic was never Monstro City's map — it was your Katsuma, your Poppet: a creature you adopted, named and came back for. A worthy alternative needs a pet that feels like yours, not a skin you scroll past.
Half the game was turning a bare room into somewhere unmistakably yours, furniture by furniture, paid for with Rox you earned. Decorating with earned currency isn't a side mode in a game like this — it's the point.
The Puzzle Palace and the Daily Challenge kept Monstro City funded: show up, play a little, earn your Rox. The best successors keep that deal — minigames that pay for the fun, never a wallet.
Moshlings were the long game: plant the right seed combo, wait, and hope. Little joys gathered over weeks, none of which expire because you took a break — that's the collecting a Moshi-style game needs.
Moshi Monsters was a whole world, and the official sequel is Mind Candy's to build. Here's exactly where Petropolis Playoverlaps with the game you miss — and where it honestly doesn't.
Four friends are free to adopt today — including the brand-new Sunny Turtle. Six more, like the very relaxed Breezy Sloth and one very small, very polite dragon, move in with the one-time Full Version.
Splashes in every puddle, then naps like a champion.
Professional sunbeam chaser and part-time yarn critic.
Bounces first, asks questions later.
Clever, quick, and secretly very cuddly.
Snack enthusiast. Napping professional.
Waddles with purpose. Loves a good slide.
Tiny flames, enormous heart.
Leaves a trail of sparkles wherever she trots.
Slow to the pool, first in line for a snack.
Hangs around all summer. Literally.
The core loop — adopting, caring, earning and decorating — is permanently free, and the room is furnished with PawCoins you win by playing, not by paying. And because your progress saves on your own device, no server shutdown can take it away. The one optional purchase is a single $4.99 Full Version. Once — then it's yours.
Free* until the servers (or Flash) went away
$0 forever — really
The closest matches are Petropolis Play (our own game — a free browser pet game where you adopt and name a pet, care for it daily and decorate its room with coins earned by playing, playable on this page), Neopets (the free pet universe from Moshi's era that's still online), Webkinz Classic (the plush-toy adoption ritual), Animal Jam (an officially supported animal world), Marapets (a fiercely independent browser pet site running since 2004) and Pou (the pocket-sized mobile care loop). Our list above walks through each honestly, catches included.
Moshi Monsters closed on 13 December 2019. The browser game was built on Adobe Flash, and with Flash reaching end-of-life, Mind Candy chose to shut the game down after 11 years rather than rebuild it. Monstro City went offline, and players' monsters, rooms and Moshling collections went with it — one of the great 'the servers are gone' losses of the 2000s web, after more than 100 million players had passed through.
Yes — officially. After years of fans asking, Mind Candy crowdfunded a comeback: its 2025 Kickstarter was funded, and an official Moshi Monsters mobile sequel is planned for 2027. The brand's younger-sibling apps (Moshi Kids, the sleep app, and Moshi Play) are still around too. Until the sequel lands, the six picks above are the honest stand-ins — ours is playable on this page.
Petropolis Play, and it's embedded above so you can judge for yourself: adopt and name your first pet in under 60 seconds, no download and no account. Neopets and Marapets are the two long-running pet sites that also work in a plain browser tab. Webkinz Classic and Animal Jam are both app installs, and the official Moshi Monsters sequel is planned for mobile in 2027.
Honestly: in the loop, not the world. What it shares with Moshi Monsters is the cozy core — adopt and name a pet, keep it fed and happy, earn coins through play, and spend them making a room yours, collecting pets, outfits and furniture along the way. What it doesn't have: it's not the official Moshi Monsters (Mind Candy's own revival is planned for 2027), there's no Monstro City, no Moshlings, no Puzzle Palace and no multiplayer. If you want Moshi itself, the official sequel is the one to watch; if you want the adopt-raise-decorate ritual today — free, in any browser — that's us.
