Back4app

Back4app is a hosted backend service that gives an app its database, user accounts and APIs without managing servers. It is built around the Parse platform and runs its databases on MongoDB Atlas or DigitalOcean.

You create data classes, and the service generates endpoints that you can call from a web or app front end. Built-in authentication covers email and social sign-in, with access control lists and role-based permissions. Custom server logic can be written as cloud functions in JavaScript, and web apps can be deployed from a GitHub repository with automatic builds. An agent feature on the site can start an app from a short description.

• MongoDB databases with a spreadsheet-style editor
• User sign-up, login and roles
• Auto-generated GraphQL and REST endpoints
• Cloud functions in JavaScript
• Web deployment from GitHub

Developers and small teams building apps who want a backend ready quickly. It also suits people who prefer a managed service to running their own database.

Databases are hosted on MongoDB Atlas or DigitalOcean. You can sign up with Google, GitHub or email, and the docs and support pages cover setup. The schema can change over time, which helps early on, but it is still worth planning the data model before you scale.
