ChakraCore is an embedded JavaScript engine designed to be integrated as a library within a host application. Its primary purpose is to provide a programmable scripting layer and a lightweight runtime environment for executing JavaScript code and managing state via a programmatic interface. The project focuses on bridging high-level scripting with low-level system calls through a C API. This allows developers to implement custom scripting engines and embed JavaScript execution directly into applications to enable task automation and functional extensions. The engine utilizes a bytecode-based

ChakraCore is an embeddable JavaScript engine and high-performance scripting runtime. It provides a just-in-time compiler that converts JavaScript source code into optimized machine code during runtime to increase execution speed and throughput. The engine utilizes a multi-tiered compilation pipeline and tiered machine code generation to balance startup time with execution speed. Memory is managed via a concurrent garbage collector that reclaims unreachable objects on background threads to minimize application pauses. The project provides capabilities for embedded JavaScript execution and au

KurrentDB is an event-native database designed for event sourcing and event-driven architectures. It stores application state as an immutable, ordered sequence of events rather than updating rows in place, preserving full history for audit, replay, and distributed consistency. The database combines event storage with real-time streaming and a built-in JavaScript projection engine that transforms and aggregates event streams into materialized views. The system provides official gRPC client libraries for Python, Node.js, Java, .NET, Go, and Rust, enabling multi-language application development

KurrentDB is an event-native database designed for event sourcing and event-driven architectures. It stores events as immutable, ordered records in streams, preserving a complete audit trail and enabling temporal queries. The database uses gRPC for all client-server and inter-node communication, providing efficient binary serialization and bidirectional streaming, and supports atomic multi-stream writes that ensure consistency across multiple streams in a single transaction. The database distinguishes itself with a built-in JavaScript projection engine that transforms, filters, and aggregates

This project is a polyglot runtime bridge and interop framework designed to execute .NET and Node.js code within a single operating system process. It functions as a cross-runtime execution engine and in-process scripting host, enabling bidirectional communication and data exchange between the Common Language Runtime and JavaScript environments to eliminate cross-process communication overhead. The framework distinguishes itself by providing a system for bidirectional asynchronous callbacks and automatic data marshalling of binary buffers and serializable values between different managed obje

Jint is a JavaScript interpreter for the .NET ecosystem that executes code without requiring a browser or Node.js environment. It is an ECMAScript compliant engine that provides a sandboxed scripting runtime with configurable limits on memory and time to run untrusted code. The engine features a native object bridge that exposes .NET classes and methods to JavaScript scripts for bidirectional data exchange. To reduce overhead during repeated executions, it utilizes a precompiled script cache to store parsed JavaScript in memory. The project covers asynchronous script execution and promise ha
