Mini WebDriver BiDi binding for Ruby

Micro k8s on Ruby - a simple tool to deploy containers to mimic a (very) minimalistic k8 cluster with a nice REST API

A Ruby library for Telegram MTProto protocol with TCP abridged transport support

Lightweight async Ruby connector for NATS

publishing, subscribing, testing, and benchmarking utilities for Nchan.

NetMap is a powerful network scanner featuring parallel host discovery, OS detection, service fingerprinting, and a custom Ruby scripting engine.

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.

Nous crawls same-host web pages, extracts readable content, and serializes clean Markdown as text or JSON.

A production-grade Ruby client for Nostr Wallet Connect (NIP-47). Handles the Nostr protocol, NIP-04 and NIP-44 v2 encryption, secp256k1 key derivation, Schnorr signing, and — most importantly — a reliable long-running WebSocket connection to the relay with heartbeat pings, forced recycle, exponential backoff, and SIGTERM handling. Developers call `pay_invoice`, `make_invoice`, `lookup_invoice`, etc. and `subscribe_to_notifications { |n| ... }` — the transport reliability is hidden.

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.

The osprey web-server. Super light weight, a little bit fluttery.

Core functionality for Pakyow

This gem provides a dedicated async HTTP processor that uses Ruby's Fiber scheduler for non-blocking I/O. Application threads hand off HTTP requests to the processor and return immediately. The processor handles hundreds of concurrent HTTP connections using fibers, then notifies the application when responses arrive via a pluggable callback mechanism. This design keeps application threads free to do other work while HTTP requests are in flight.
