## Create secure and private web apps using only static JavaScript, HTML, and CSS.

## What is Userbase?

Userbase is the easiest way to add user accounts and data persistence to your static site. All Userbase features are accessible through a very simple [JavaScript SDK](https://userbase.com/docs/sdk/), directly from the browser. No backend necessary.

### Built-in user accounts

Userbase takes care of your user accounts. The Userbase SDK lets you sign up, login, and logout users directly from your static site.

### Zero-management database

Instead of sending database queries to a server, Userbase sends the user's data to the browser. Queries happen client-side, and there is nothing on the backend to manage or worry about.

### End-to-end encryption

Userbase encrypts all database operations in the browser with user-controlled keys. This helps you prevent personal data misuse, and lets you offer a high level of data privacy.

### Open source

Userbase is [100% open source](https://github.com/encrypted-dev/userbase), MIT licensed. You can host it yourself always under your control, or we can run it for you for a full serverless experience.

## When would I use it?

If you're building a web app, you will likely need a database and a backend. Userbase can replace both...

-   If you want to build a web app without writing any backend code.
-   If you want secure authentication out of the box.
-   If you want to store user data securely.
-   If you want to radically simplify your GDPR compliance.
-   And if you want to keep things really simple.
