FishNET is a script engine for the .NET Framework. FishNET allows you to execute a source file written in C#, VB.NET or JScript.NET without having to build/compile it. FishNET can be compared almost directly to the cscript and wscript functionality of w

Closure Compiler is a production-grade JavaScript optimizer and checker that parses JS, analyzes it, removes dead code, rewrites and minifies what remains, and emits faster, smaller bundles. Beyond minification, it performs advanced optimizations such as inlining, property collapsing, type-guided rewrites, and cross-module motion, often yielding substantial load-time wins. It includes a strong static checker that validates syntax, variable references, and type annotations (Closure types or JSDoc), catching bugs early and enabling aggressive transformations safely. The ecosystem provides a Java implementation, npm/JS builds, and documentation for integrating in modern toolchains. Closure Compiler has been used extensively at scale within Google and by the broader community, proving its robustness on very large codebases. Companion repositories track npm packaging and a JS-only variant for environments where running Java is undesirable.

Hogan.js is a 2.5k JS templating engine developed at Twitter. Use it as a part of your asset packager to compile templates ahead of time or include it in your browser to handle dynamic templates. If you're developing with Node.js, just use NPM to add the Hogan package. Hogan.js was developed against the mustache test suite, so everything that holds true for templates is also the case for hogan.js. That means you get variables, sections, lambdas, partials, filters, and everything else you've come to expect from mustache templating, only much, much faster. Use hogan.compile() to precompile your templates into vanilla JS. It's best to serve your templates precompiled whenever you can (rather than the raw templates), as parsing is the most time consuming operation. Once compiled, call the render() method with a context and optional partials object. If supplying partials, you can compile them ahead of time, or pass string templates.

Ino-L is a TUI programming language for Windows that compiles into MS-DOS batch files. Ino-L stands for Innova Language, because Innova is French for innovation. The purpose of the language is to allow programmers the same functionality and abilities of batch files, but with simpler syntax and limited GUI, along with other things MS-DOS does not natively support. Your MS-DOS code can also be incorporated into the Ino-L source code, along with JavaScript and VisualBasic.

JS/CC is a parser generator for JavaScript/ECMAScript, which is entirely written in ECMAScript itself. It produces LALR(1) parsers with integrated lexical analyzers. JS/CC can run as a website or be invoked from a console, and runs on several platforms.

JSGold is a GOLD Parser Engine in C++ for generating context-free grammar parsers in javascript.

This is an Eclipse plugin based on JSMin Javascript minifier. It adds an Ant task called jsminify that copies Javascript files and minifies them while copying, thus leaving the sources intact.

This is a JavaScript to Scheme translator written entirely in Scheme. Currently tested only with Guile

JavaScriptFlash: Compiling JavaScript to SWF JavaScriptFlash is a web-based platform to support the JavaScript web programmers to develop Flash applications in JavaScript. It compiles the JavaScript code following certain rules into a Flash SWF file

Narrative JavaScript is a small extension to the JavaScript language that enables blocking capabilities for asynchronous operations. This makes writing asynchronous code sequences easier and increases code readability.

Pyjamas is a python to Javascript compiler, Widget set, Framework and Toolkit for Application development that runs on Web browsers. The developer need not know anything about AJAX: all the AJAX tricks, for all major browsers, are entirely taken care of.

Rev = Really Easy Validation - write your form validation code once in this simple and powerful language that generates code for JavaScript, Perl, PHP, and Java. With Rev you get server side and client side data validation with no duplicated code.

RockScript is the world's smallest Java-based JavaScript interpreter, runs smoothly in any J2ME phones. The binary size of core engine including native objects/methods is less than 25K (obfuscated & JAR'ed). It can be integrated into any J2ME apps.

Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD. ES modules let you freely and seamlessly combine the most useful individual functions from your favorite libraries. This will eventually be possible natively everywhere, but Rollup lets you do it today. Rollup can be used either through a command line interface with an optional configuration file, or else through its JavaScript API. Rollup allows you to write your code using the new module system, and will then compile it back down to existing supported formats such as CommonJS modules, AMD modules, and IIFE-style scripts. This means that you get to write future-proof code.

Picture Gallery viewable with HTML web browsers. All dynamics is implemented at client-side in JavaScript. This approach is useful when the server side is able to provide only static contents, or if the gallery is stored on CDROM or other media.

Schism is an experimental compiler that translates Scheme programs into WebAssembly, allowing Scheme code to execute in both browser environments and server platforms like Node.js. Developed initially by Google researchers, the project was designed to explore the intersection of functional programming and WebAssembly’s low-level efficiency. Schism supports a subset of the R6RS Scheme standard and is self-hosting, meaning that the compiler itself is written in and compiled by Schism. Its architecture demonstrates advanced compiler design techniques such as staged compilation and snapshot-based bootstrapping. The project focuses on leveraging WebAssembly’s experimental capabilities, including reference types and tail calls, to test the limits of language portability and runtime performance. Though no longer actively maintained, Schism remains a valuable example of how high-level languages can be mapped to WebAssembly and offers insights into language implementation.

Silis OS is a online based operating system which will allow users to access their files and programs from any where in the world.

Smee allows ECMAScript to be used as an extension language for Smalltalk applications.

Smith is an open source, cross-platform ColdFusion® engine, written entirely in Java. Running on top of Java Runtime Environment and Java Servlet Container, it can be deployed virtually on any operating system and work with any web server.

SuperClass is a JavaScript pre-processor/interpreter object, designed to facilitate class-based OOP in JavaScript. NOTE: Project is closed. Replaced by: http://sourceforge.net/projects/jsclass

The SuperWikia Alpha 1.0 application is an IDE specifically developed for 3D and graphic content. Its built upon the Unity foundation and incorporates various libraries from Komodo IDE, wxDevC++, CodeBlocks, QT Creator and other applications. Its Realtime purpose is an IDE (codesmith developer access), its Runtime (U/I) function is as a space building simulator, operating in conjunction with the SuperWikia 'Navigator' user interface to simulate space economics and fleet operations. It allows users (known as 'data fleet navigators' or DFN's) to compete in tourneys over vast regions known as 'expanses' and to create envoys that manage onsite and offsite stations. Using additional SuperWikia components, users may enhance their experience with plugins and 'dataplates' that help build the Runtime environment. Codesmiths (SuperWikia Alpha developers) can also build on top of the codebase using 'transcribes', acronym/algebraic encodes that differentiate codesmith works.
