Appwrite

Appwrite is an open-source, self-hosted, and cloud-managed Backend-as-a-Service (BaaS) platform designed to streamline application development. It abstracts the complexity of building, securing, and maintaining a custom backend by exposing a unified set of REST, GraphQL, and Realtime APIs. By managing core infrastructure tasks, Appwrite enables developers to focus entirely on building frontend experiences across web, mobile, and desktop ecosystems.

Core Infrastructure Services
Appwrite consolidates the essential building blocks of modern applications into a single, integrated platform:

Authentication & User Management: Securely registers and authenticates users with a wide range of onboarding flows. It supports traditional email/password and anonymous logins, passwordless magic URLs, phone/SMS authentication, and a broad array of OAuth providers (such as Google, GitHub, and Apple).

Scalable Databases: Offers a flexible, schema-based data store that handles collections and documents.
