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.

OpenWA turns WhatsApp sessions into a self-hosted REST API with a web dashboard for managing accounts, webhooks, API keys, contacts, messages, and infrastructure. 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.

Fusio is a self-hosted, open-source API management platform and gateway written in PHP. It can expose databases, microservices, and custom PHP or JavaScript actions as controlled API products, with a developer portal, SDK generation, usage monitoring, subscription plans, and quotas. Native MCP support can present selected backend actions as tools for AI agents. Docker Compose is the documented quick start, with manual installation also available.

RocketMQ-Rust is a Rust reimplementation of Apache RocketMQ that includes NameServer, Broker, Controller, Proxy, storage, and producer, consumer, and administration components. It can support Rust-native messaging deployments or interoperate with existing Apache RocketMQ Java clients and servers through protocol compatibility. Building the workspace requires Rust 1.85.0 or later.
