Userbase: 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 user data persistence to your static site. All Userbase features are accessible through a very simple JavaScript 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, 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 of those things...

• 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.

How do I start?

The easiest way to start using Userbase is to create a free Admin account and follow the Quickstart guide. If you have any questions, or if there's anything we can do to help you with your web app, please get in touch. Thank you!

Browser Compatibility

We have tested support for the following browsers:

• Chrome >= 78
• Safari >= 11
• Firefox >= 71
• Chrome Android >= 80
• Safari iOS >= 13

To support Internet Explorer, you will need to use a Promise polyfill such as this one.
