RxSwift is a reactive programming library for Swift that provides a framework for managing push-based data flows and composing asynchronous, event-based programs. It utilizes observable sequences and functional operators to transform and filter asynchronous sequences through a declarative approach. The library is distinguished by its ability to link asynchronous data streams directly to user interface elements, automating view updates via reactive data binding. It includes specialized tools for tracking UI control properties and events on the main thread, as well as the ability to encapsulate

DreamBerd is a general purpose programming language designed for building applications with integrated support for reactive state, time-aware memory management, and embedded user interface markup. It functions as a programming environment that tracks dynamic values and coordinates asynchronous tasks through sequential execution constraints. The language is distinguished by its ability to track variable history, providing dedicated keywords to retrieve previous, current, and future values of variables during execution. It further differentiates itself through a memory model that controls varia

Capybara is a browser automation library and web application acceptance test framework used to simulate user behavior and verify functional requirements. It serves as a cross-browser testing tool and headless browser orchestrator, allowing for the execution of test suites across multiple browser engines. The project provides a driver-agnostic interaction layer that abstracts different browser engines, enabling users to switch between headless and full browser drivers. It supports multi-user session simulation by maintaining independent browser states and cookies to test interactions between i

CasperJS is a scripting utility and testing framework for automating web scenarios via headless browsers. It enables the execution of navigation steps and form inputs to automate complex user scenarios, extract web data, and validate the state of remote pages. The project provides specific tooling for PhantomJS and SlimerJS, allowing users to write programmable sequences for web navigation and data extraction. It includes capabilities for capturing visual snapshots of full pages or specific elements to perform user interface regression testing. The framework covers broad automation areas inc

EarlGrey is an iOS UI automation test framework that enables writing and running automated tests simulating real user interactions. It provides a synchronized test execution engine that automatically waits for animations, network requests, and run-loop states to complete before performing test actions or assertions, producing stable and repeatable results across test runs. The framework distinguishes itself through out-of-process interaction handling, managing system alerts and app switching during tests, and a pixel-level visibility checker that verifies UI elements are actually visible and

RxPY is a functional reactive programming library and a ReactiveX observable library for Python. It serves as an asynchronous stream processor and event-driven coordination framework used to build data pipelines that react to changes in state or streams of events over time. The library provides a toolkit for composing asynchronous and event-based programs using observable sequences and operators. It distinguishes itself through the use of configurable schedulers to manage concurrency, timing, and subscription lifecycles. The project covers a wide range of stream processing capabilities, incl

cppcoro is a C++ coroutine library and concurrency toolkit providing primitives for asynchronous tasks, lazy generators, and non-blocking execution. It functions as an asynchronous I/O framework for managing network sockets and file operations through an event loop. The library features a work-stealing thread pool for distributing tasks across multiple cores and a set of async generators for producing lazy sequences of values both synchronously and asynchronously. It includes a concurrency toolkit with async mutexes, latches, and shared tasks to coordinate multi-threaded execution. Its capab

Reactor is a reactive streams library and framework for building asynchronous data pipelines. It provides a system for coordinating execution contexts via an asynchronous event-loop manager, alongside a set of reactive abstractions for implementing high-performance TCP, UDP, QUIC, and HTTP services. The project includes a specialized testing tool for verifying the timing and order of asynchronous data flows and a bill of materials to synchronize compatible versions of core reactive libraries and networking add-ons. Its capability surface covers non-blocking network services, demand-based bac

Taiko is a browser automation framework and web end-to-end testing library used to perform programmatic user actions and verify application behavior. It functions as a headless browser testing tool capable of simulating real interactions and asserting page states in Chromium and Firefox. The project includes a browser interaction recorder that captures live actions and exports them as executable JavaScript automation scripts. It also serves as a web accessibility auditor, analyzing pages to detect accessibility violations and ensure compliance with inclusive design standards. The framework c
