Appwrite is a self-hosted Firebase alternative that provides a full backend platform for web and mobile applications, covering authentication, databases, file storage, serverless functions, and real-time messaging in one open source stack.
The Problem
Firebase offers convenience at the cost of vendor lock-in and data control. Firestore's proprietary query model makes migration difficult, and Google's pricing charges for reads, writes, and storage in ways that are hard to predict as an application scales. Teams in markets with strict data residency requirements cannot use Firebase at all, and there is no on-premise option.
How Appwrite Solves It
Appwrite runs on Docker and installs on any server in under 15 minutes with a single command. It exposes a consistent REST and Realtime API across all its services, so a mobile app and a web app share the same backend without separate SDKs for each service. Each module (auth, database, storage, functions) is independently configurable, and the admin console handles user management, collection schema, and function deployments without touching the command line.

Key Features
- Auth supporting email/password, magic links, OAuth providers, and anonymous sessions
- Document database with collection-level permissions and relationship support
- File storage with encryption, compression, and image transformation
- Serverless functions running in isolated containers with no cold start penalty
- Real-time subscriptions to any Appwrite event via WebSocket
- Messaging API for push notifications, email, and SMS through one endpoint
Self-Hosting
Appwrite installs with a single Docker command on any Linux server. The official quick-start script sets up auth, database, storage, and functions in under 15 minutes. A 2 GB RAM server handles development and small production workloads; scale by adding compute as needed.

Who It's For
Appwrite is best for developers building mobile or web applications who want Firebase's developer experience with full data ownership and no per-read pricing. It suits teams in regulated industries or regions where cloud-hosted backends are not an option.
Compared to Firebase
Unlike Firebase, Appwrite runs entirely on your own server with no per-operation pricing. Your data stays in your infrastructure, and the SDK covers the same auth, database, storage, and functions surface without a proprietary data format.
