Node-RED
Low-code programming for event-driven applications
Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click. Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette. Flows can be then deployed to the runtime in a single-click. JavaScript functions can be created within the editor using a rich text editor. A built-in library allows you to save useful functions, templates or flows for re-use. The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run at the edge of the network on low-cost hardware such as the Raspberry Pi as well as in the cloud. -

Wasp
A programming language that understands what a web app is
Wasp (Web Application Specification Language) is a declarative DSL (domain-specific language) for developing, building and deploying modern full-stack web apps with less code. Concepts such as app, page, user, login, frontend, production, etc. are baked into the language, bringing a new level of expressiveness and allowing you to get more work done with fewer lines of code. While describing high-level features with Wasp, you still write the rest of your logic in your favorite technologies (currently React, NodeJS, Prisma). Wasp is in alpha and is therefore likely to change a lot, have bugs and miss important features. Due to its expressiveness, you can create and deploy a production-ready web app from scratch with very few lines of concise, consistent, declarative code. When you need more control than Wasp offers, you can write code in existing technologies such as js/html/css/... and combine it with Wasp code! -

Mint
A refreshing programming language for the front-end web
Mint has all the tools you need to write error-free, easily readable, and maintainable applications in record time. In Mint you can style elements directly with CSS using style blocks. Inside a style block, you can nest as many sub selectors and media queries as you like. Interpolate any Mint expressions in any value using the interpolation syntax. You can even use if and case expressions inside any block to apply styles conditionally. In Mint a store contains and manages some data. Stores are globally accessible and can be connected to components. When the data in a store changes the connected components are re-rendered. In Mint routing is a language feature instead of a library. Routes can be defined in a routes block, with support for typed path parameters. The runtime handles clicks on anchor tags and navigates in a smart way so you don't have to. You can inline any JavaScript code easily by using bacticks. -

TypeScript
Application-scale JavaScript
TypeScript is an open source programming language that is a typed superset of JavaScript. It adds optional static typing to JavaScript, which can support tools for large-scale JavaScript applications for any browser, host and OS. TypeScript compiles to clean, simple JavaScript, and uses existing JavaScript code and libraries. It also offers support for the latest and evolving JavaScript features, such as async functions and decorators. -

V Programming Language
Simple, fast, safe, compiled language for developing software
Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V avoids doing unnecessary allocations in the first place by using value types, and string buffers, promoting a simple abstraction-free code style. Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object. -

PLT (Programming Languages Theory)
Programming Language Theory
Curated roadmap to Programming Language Theory, collecting seminal papers, books, and resources into a navigable structure for self-study. It spans foundational topics like lambda calculus, type systems, interpreters, compilers, and formal semantics, while also pointing to contemporary areas such as effect systems, dependent types, and verification. Each section clusters materials by theme so learners can build understanding step by step instead of grazing at random. The list emphasizes primary sources and high-quality lectures, encouraging readers to engage with rigorous treatments rather than superficial summaries. Itโs designed to serve both as a starting guide for newcomers and as a reference index for experienced practitioners, filling in gaps. By treating PL theory as an accessible, progressive curriculum, the repository lowers the barrier to serious study without diluting the subject. -

Ino-L
Simple programming language for Windows.
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. -

Enterprise
The Enterpriseโข programming language
Enterprise is a satirical open-source project that humorously critiques corporate software development practices by presenting intentionally overengineered and unnecessarily complex code structures. Rather than aiming to solve a practical technical problem, it serves as a parody of enterprise-grade software, showcasing exaggerated patterns such as excessive abstraction, redundant layers, and convoluted architectures. The repository is often used as a teaching tool to highlight anti-patterns in software engineering, helping developers recognize and avoid overly complicated designs in real-world projects. Despite its humorous nature, the project is technically functional and demonstrates how complexity can accumulate when design principles are misapplied. It resonates particularly with developers who have experience in large organizations, where similar patterns sometimes emerge unintentionally. -

stylus
Expressive, robust, feature-rich CSS language built for nodejs
Stylus is a revolutionary new language, providing an efficient, dynamic, and expressive way to generate CSS. Supporting both an indented syntax and regular CSS style. Installing Stylus is very easy once you have Node.js. So get the binaries for your platform and make sure that they also include npm, Nodeโs package manager. Stylus features powerful in-language function definitions. Function definitions appear identical to mixins; however, functions may return a value. Optional arguments may default to a given expression. With Stylus we may even default arguments to earlier arguments! Stylus is an innovative stylesheet language that compiles down to CSS. Inspired by SASS, Stylus is built with node.js and capable of running in the browser. Stylus is โpythonicโ (i.e. indentation-based). Whitespace is significant, so we substitute { and } with an indent, and an outdent. Stylus, just like CSS, allows you to define properties for several selectors at once through comma separation. -
