## What it is
Userbase is an open-source backend-as-a-service that adds user accounts and end-to-end encrypted data persistence to static web apps via a simple JavaScript SDK, with no backend code required. It can be used as a hosted serverless service or self-hosted on AWS.

## Use cases
- add user sign-up and login to a static site without a backend
- store user data in a browser-accessible encrypted database
- build a web app with only JavaScript, HTML, and CSS
- simplify GDPR compliance with end-to-end encryption
- share encrypted data securely between users
- accept Stripe payments in a static web app
- self-host a private backend for user data

## When to choose
- you want authentication and persistence for a static site with zero backend code
- privacy and end-to-end encryption of user data are priorities
- you want to self-host the entire stack under your control

## When to avoid
- you need complex server-side queries, joins, or relational data
- you require heavy backend logic, integrations, or custom APIs
- you need large-scale storage beyond simple document-style data
