PrivateGPT sits between an OpenAI-compatible local inference server and the applications built on top of it. Its API covers messages, file ingestion, citation-backed retrieval, custom tools, database and CSV access, and MCP connectors, following the Claude API as a reference. The included web interface is mainly a demonstrator and debugger; developers are expected to build their own user experience around the API.

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.

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.
