Appwrite Backend Platform

Appwrite is an open-source backend-as-a-service platform that provides databases, authentication, file storage, serverless functions, real-time messaging, and task scheduling for web, mobile, and Flutter applications through a self-hostable or cloud-managed API. The database component stores data in collections with typed attributes including strings, integers, booleans, floats, emails, URLs, dates, and relationship references, with automatic indexing, query permissions at the document level, and a RESTful API that supports filtering, ordering, pagination, and full-text search on any attribute. The authentication system handles email and password login, magic URL authentication, phone number OTP verification, anonymous sessions, and OAuth social login through over thirty providers including Google, GitHub, Apple, Discord, and Microsoft, with configurable password recovery flows and email verification. The storage service accepts file uploads up to the configured size limit, generates image previews and thumbnails through on-the-fly transformation, and delivers files through a global CDN with configurable access permissions. Cloud Functions execute JavaScript, TypeScript, Python, Ruby, PHP, Dart, Swift, and Kotlin code in isolated containers, triggered by HTTP requests, cron schedules, or platform events like document creation or user registration, with environment variables and secrets managed through the dashboard. Real-time subscriptions push events through WebSocket connections when data changes, enabling collaborative applications and live interfaces. The platform ships as a Docker Compose stack that can be deployed on any infrastructure in minutes, or through the managed cloud with automatic scaling and backups. SDKs are available for Web, Flutter, iOS, Android, React Native, Apple, Node.js, Python, Ruby, PHP, Go, Dart, and Kotlin.
