Engine client

Prosody offers Ruby bindings to the Prosody Kafka client, providing features for message production and consumption, including configurable retry mechanisms, failure handling strategies, and integrated OpenTelemetry support for distributed tracing.

Pyroscope FFI Integration for Ruby

Experimental alpha Ruby bindings (native extension) for the quietquic Rust crate.

It's a string searching gem that locates elements of a finite set of strings (the "dictionary") within an input text.

ranma wraps a suite of Rust crates: tao (windowing and event loop), wry (WebView), Vello+wgpu (GPU 2D graphics), muda (native menus), tray-icon (system tray), arboard (clipboard), global-hotkey, and dark-light (theme detection).

A Ruby gem that provides fast CSV processing capabilities using Rust extensions for performance-critical operations

Ruby bindings to MRML, a reimplementation of the MJML markup language in Rust.

Ruby bindings for the redact-ner crate, providing Named Entity Recognition for PII detection using quantized ONNX models through the ONNX Runtime.

Processor of REMIND_ME comments in the code, reminding us to revisit parts of code

Ruby bindings (via Rust/magnus) for liblz4, using lz4-sys FFI. Provides block-format and frame-format LZ4 compress/decompress with optional dictionary support. Designed to be safe to call from multiple Ractors, unlike existing Ruby LZ4 gems.

Embed and verify C2PA content provenance and authenticity credentials in images, video, and audio files. Ruby bindings for the official Rust c2pa-rs library.

Finite state transducer backed ordered sets and maps via the Rust fst crate by BurntSushi

A Ruby gem that compiles a native Rust extension with magnus and rb-sys to expose Turbovec APIs.

This gem brings in a rust library (RQRR) to detect QR codes in images.

A V8 engine for Ruby built on rusty_v8 and Magnus: eval, host functions, ES modules, snapshots, realms, bytecode cache, faithful value marshalling, and an ExecJS adapter.

Ruby bindings (via Rust/magnus) for the Zstandard compressor with persistent ZSTD_CCtx / ZSTD_DCtx contexts that are reused across calls. Provides Zstd frame compress/decompress at module level and a stateful Dictionary class for dict-bound compression. Designed to be safe to call from multiple Ractors and competitive with rlz4 on small messages, where per-call context allocation in zstd-ruby dominates the cost.

An unofficial Ruby wrapper for Tiktoken, a BPE tokenizer written by and used by OpenAI. It can be used to count the number of tokens in text before sending it to OpenAI APIs. This is a fork of tiktoken_ruby by IAPark, which has been cross-compiled for multiple platforms. This way compilation with Rust extensions doesn't need to happen wherever you are deploying it.

Simple, safe way to store and distribute tensors

Embeddable, dependency-free SCSS/Sass compiler aiming at byte-for-byte dart-sass parity, shipped as a Rust native extension (magnus + rb-sys).
