API and Backend Builders
Backend platforms for a mobile or web app that need real logic, not just a spreadsheet standing in for a database. Auth, custom endpoints, and server-side workflows get built visually, then called from any front end over a standard API.

Frequently asked questions
What is the difference between a headless CMS and a backend-as-a-service?
A headless CMS focuses on managing content and auto-generating APIs from custom content types. A backend-as-a-service provides a broader suite of tools including authentication, real-time databases, and cloud functions for app logic.
Can I use these platforms if I already have an existing Postgres database?
Yes. Several options allow you to transform existing Postgres databases into production-ready REST or GraphQL APIs. Some even offer spreadsheet-like interfaces to manage that data.
Do I need to know how to code to build complex server-side logic?
Not necessarily. Some platforms let you build logic through visual workflows or no-code interfaces without writing server code. Other options are designed for developers and rely on TypeScript or custom functions.
How do these platforms handle real-time data updates?
Many of these options include built-in real-time features that sync data to your frontend automatically. This is useful for apps that need instant updates without constant manual refreshing.
