Unlike a regular database, all Userbase queries run in the browser. The server-side is just a dumb data store, and there's nothing on the backend to manage or worry about.
Userbase takes care of your user accounts. It comes with built-in APIs for user signups, logins, and access control.
Userbase won't show you what your users store in your web app. It spares you from the liability of handling user data by encrypting everything in the browser, using keys that always stay with the user.
If you're building a web app, you will likely need a database and a backend. Userbase can replace both of those things...
Userbase will be available around mid-December 2019. Enter your email to receive important updates in your inbox.
Userbase is 100% open-source, MIT licensed. You can modify and extend the backend to your liking, and run it yourself in your AWS account, always under your control.
Or for just $39/month you can go fully serverless, backendless, databaseless, and AWSless!
