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, 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.
