Open source
You don't need to install anything, create an account, or understand how any of this works. Seratus runs in your browser, right now. This page is for people who want to go further: use it without internet, or keep their own copy of the code.
If you have internet, that's all you need. Open Seratus in any browser on any device. Chrome, Safari, Firefox, Edge: all work. Your data saves to your browser automatically. Nothing leaves your device.
Bookmark it so you can come back easily. On your phone, you can add it to your home screen so it feels like an app.
If you'd like Seratus to work even when you're offline, you can download the files to your computer. No GitHub account needed. No terminal. Takes about two minutes.
Go to the Seratus page on GitHub (a website where the code lives publicly): github.com/jesdonut/lifeOS2.0
Look for a green button that says Code. Click it. A small menu opens. Click Download ZIP. A file will download to your computer, usually into your Downloads folder.
The file you downloaded is a ZIP. A ZIP is a compressed folder, like a box with everything inside. You need to open the box before you can use what's in it.
On a Mac: Find the ZIP in your Downloads folder and double-click it. A new folder appears right next to it. That's the unpacked version. Open that folder.
On Windows: Find the ZIP in your Downloads folder. Right-click it and choose Extract All. Click Extract. A new folder appears. Open that folder.
Inside the folder, find the file called index.html. It will have a browser icon on it (a compass, a flame, or similar depending on your default browser). Double-click it.
Seratus opens in your browser, exactly as it does online. Your data saves to that browser. It works completely offline from this point. The files stay on your computer and nothing is sent anywhere.
One thing to know: if you open Seratus from the downloaded files and also use it online, they don't share data. Each browser and each location keeps its own separate data. Pick one and stick with it, or export from one and import into the other.
If you want your own independent copy of the code on GitHub that you can modify and deploy yourself, you can fork the repository: Fork on GitHub →
What does forking mean? Forking creates a full copy of the entire project inside your own GitHub account. Your copy is independent. You can change anything, deploy it to your own URL for free using Vercel, and keep it running exactly how you want.
If you've never done this before, GitHub's guide on forking is a good starting point.
If something isn't working, open an issue on GitHub and describe what you tried.
