appwrite

@appwriteTypeScript

Backend services and hosting for web, mobile, and AI apps

Project overview

Appwrite brings common application backends into one platform so web, mobile, and AI teams can avoid assembling a fragmented stack. It covers identity and data management, file storage, server-side functions, realtime communication, and web hosting. Teams can use the managed cloud or self-host in Docker, Kubernetes, and other container environments, then connect through SDKs or REST, WebSocket, and GraphQL APIs.

Self-host a multi-session WhatsApp API with web management.

Project overview

Its pluggable design supports SQLite or PostgreSQL, optional Redis caching, and local or S3-compatible media storage, with Docker provided for deployment. An optional MCP endpoint exposes a curated subset of tools to AI agents while keeping the full REST surface available.
