The short answer
If you came looking for something like BitLife that does not want an install, OpenLifeSim is the closest thing that opens in a tab. Both games are one person's whole life, one turn per year, decided by numbers you can read. The differences are where they run, what they cost, and how much of the machinery they show you.
BitLife is a mobile app you install from the App Store or Google Play, and it is free to play with adverts and an optional paid tier. OpenLifeSim is a web page: it runs on a phone, a tablet or a desktop, it has no adverts at all, and the entire game is free. It will also install to a home screen as a PWA from your browser's own share or install menu, which still downloads nothing from a store.
OpenLifeSim vs BitLife, side by side
| OpenLifeSim | BitLife | |
|---|---|---|
| Where it runs | Any web browser — phone, tablet, desktop | iOS and Android app |
| Install needed | No — it is a web page | Yes, from an app store |
| Account needed | No | Not to play |
| Adverts | None, anywhere | Yes, on the free tier |
| Cost to play the whole game | Free | Free with adverts; a paid tier removes them and adds content |
| What money buys | Nothing you play. $9 one-time keeps a life: cloud saves and more save slots | A subscription tier and in-app purchases that unlock content |
| Jobs | 155 jobs across 22 career ladders, plus 8 special careers | A broad job list plus special careers |
| Moving country | 22 countries with their own wages, rents, visas, currencies and 14 languages to learn | Emigration between countries |
| How a year is shown | A dashboard of readouts — bars, thresholds and figures you scan | A scrolling text log you read |
| Saves | In the browser by default; cloud saves are the paid extra | On the device, tied to the app |
This table is about what each game is, not which is better. BitLife is a polished app with years of content behind it. OpenLifeSim is made by one person in the open, and the honest pitch is narrower: it is free, it is in a tab, and it shows you its numbers.
What is actually different about OpenLifeSim
A tracked number is a readout, not a sentence
Most life sims narrate a year at you and leave you to work out whether it went well. OpenLifeSim is built the other way round: a value you are tracking gets a bar with its threshold drawn on it, so you can see at a glance that 52% is a fail when the mark is 68%. You come back each year to answer one question — am I getting better or worse at this — and that answer is meant to be readable in a second, on a phone, without reading a paragraph.
The world is a place with prices in it
Twenty-two countries, each with its own wage level, rents, tuition, healthcare and visa rules, and fourteen languages you can be fluent or useless in. Moving is a real decision with a real bill rather than a menu option, and a job that pays well in one country is an ordinary living in another.
It is free because the game is not the product
Nothing in the game is behind a paywall, an advert or a subscription. The one-time purchases exist so a life can outlive your browser's storage — cloud saves, more lives on the shelf at once, and a way to hand a life to somebody else to play on. If you never pay, you never hit a wall.
Common questions
Is there a free alternative to BitLife?
OpenLifeSim is a free BitLife alternative that runs in a browser tab: no download, no app store, no account and no adverts. The whole game is free, and the optional one-time purchases only add cloud saves and extra save slots.
Can I play a life simulator in my browser without downloading anything?
Yes. OpenLifeSim runs entirely in a web browser on desktop, tablet and phone, with nothing to install and no sign-up. It also installs to a home screen as a PWA from the browser's own menu, which still downloads nothing from a store.
Is OpenLifeSim on iOS or Android?
There is no app-store listing, and there does not need to be. It is a web page, so it opens on iOS and Android in Safari or Chrome exactly as it does on a desktop, and it can be added to the home screen from there.
How long does one life take?
A life runs one year per turn from birth to death, which is usually a sitting or two. The game saves in the browser, so you can leave a life half-lived and come back to it.
