A HTTP client and server library.

A Redis client library.

An implementation of the Rack protocol/specification.

OpenCypher Adapter ala ActiveRecord

Transparent Ruby IPC over an asynchronous message bus.

A high-performance NATS client built on the async framework, providing fiber-based concurrency for better resource efficiency. Built on top of nats-pure with full API compatibility. WARNING: This project was developed entirely by the Windsurf AI code agent and should be considered experimental.

A lowish-level SSH server library for Ruby

Async-based Ruby library for interacting with the open source telephony platform FreeSWITCH.

Ruby LSP server that provides code completion using LLM FIM (Fill-In-the-Middle). Supports Ollama and other OpenAI API compatible backends.

An asynchronous server that creates events for your event-driven application to use

Lightweight async Ruby connector for NATS

Pure Ruby implementation of nanomsg's Scalability Protocols (SP) on top of async + io-stream. Per-socket HWM, opportunistic batching, wire-compatible with libnng over inproc/ipc/tcp.

Pure Ruby implementation of ZeroMQ with all socket types (REQ/REP, PUB/SUB, PUSH/PULL, DEALER/ROUTER, and draft types) and TCP/IPC/inproc transports. Built on protocol-zmtp (ZMTP 3.1 wire protocol) and Async fibers. No native libraries required.

Pure Ruby implementation of the MQTT 3.1.1 and 5.0 packet codec: encode, decode, VBI, properties, reason codes. Protocol::MQTT::Connection wraps an IO::Stream to read and write packets. No I/O beyond IO::Stream.

Provides abstractions to handle the multipart format.

Easy RSMP site and supervisor communication.

Pure Ruby implementation of MQTT — client and broker in one gem — built on async, io-stream, and protocol-mqtt. Fiber-first, pluggable transports (tcp, tls, ws, ipc), pluggable persistence (in-memory, PStore).

Adds ws:// and wss:// transports to zzq, built on async-websocket. Registers both schemes on require; no zzq core changes required.
