Open-source alternatives to Hydra

A full-featured NATS messaging client for Common Lisp.

Swift coroutines for iOS, macOS and Linux.

Bolts-ObjC is an Objective-C mobile development library providing tools for coordinating asynchronous operations and routing deep links within native applications. It functions as a framework for managing background tasks and resolving navigation metadata to direct users to specific content. The library includes a deep link routing engine and an app link navigator that resolve handler compatibility to launch native experiences or trigger web browser fallbacks. It also features a mobile analytics link logger to track user movement through deep links for integration with external analytics plat

Bolts-Swift is a concurrency control framework designed to manage asynchronous workflows in native mobile applications. It provides a collection of primitives that allow developers to orchestrate background operations through a promise-based model, replacing deeply nested callback structures with chainable task sequences. The library distinguishes itself by offering granular control over task lifecycles and execution environments. It enables developers to define custom executors for specific threading contexts and provides mechanisms to manually signal the completion, error, or cancellation o

Sento - Actor framework featuring actors and agents for easy access to state and asynchronous operations.

PromiseKit is a future-based concurrency framework and promise library for Swift and Objective-C. It functions as an asynchronous workflow coordinator, representing the eventual result of an operation to simplify concurrency logic and replace nested callback structures. The framework enables the coordination of both sequential and parallel asynchronous tasks. It provides a structured pipeline for chaining operations, allowing the results of one task to be passed into the next and facilitating the execution of multiple operations simultaneously. The library includes a state-machine based reso
