MicroPython
Python implementation for microcontrollers and constrained systems
MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments. The MicroPython pyboard is a compact electronic circuit board that runs MicroPython on the bare metal, giving you a low-level Python operating system that can be used to control all kinds of electronic projects. MicroPython is packed full of advanced features such as an interactive prompt, arbitrary precision integers, closures, list comprehension, generators, exception handling and more. Yet it is compact enough to fit and run within just 256k of code space and 16k of RAM. MicroPython aims to be as compatible with normal Python as possible to allow you to transfer code with ease from the desktop to a microcontroller or embedded system. -

Vercel Zero
The programming language for agents
Zero is an experimental programming language from Vercel Labs designed with AI agents as first-class users. The project explores what a language, tooling system, and standard library might look like if agents need to read, debug, repair, and ship code reliably. It focuses on a small and regular language surface, structured diagnostics, predictable tooling, and machine-readable outputs. Zero is still pre-1 and intentionally unstable, so its syntax and APIs are meant for exploration rather than production use. The project includes commands for checking, running, building, graph inspection, size reporting, diagnostics, and repair-oriented workflows. Its main goal is to create a systems-oriented language environment that agents can understand and act on without relying only on human-readable compiler messages. -

Ring Programming Language
Simple and flexible programming language for applications development
Simple and flexible programming language for applications development. Ring is a practical general-purpose multi-paradigm language. The supported programming paradigms are Imperative, Procedural, Object-Oriented, Functional, Metaprogramming, Declarative programming using nested structures, and Natural programming. The language is portable (MS-DOS, Windows, Linux, macOS, Android, WebAssembly, etc.) and can be used to create Console, GUI, Web, Games, and Mobile applications. -

Seed7
Interpreter and compiler for the Seed7 programming language.
Interpreter, compiler, libraries, documentation and examples for the Seed7 programming language. Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C/C++ and Java. In Seed7 new statements and operators can be declared easily. Functions with type results and type parameters are more elegant than a template or generics concept. Object orientation is used where it brings advantages and not in places where other solutions are more obvious. Seed7 spares no effort to support portable programming. Several driver libraries assure that the access to operating system resources such as files, directories, network, clock, keyboard, console and graphics are done in a portable way. Although Seed7 contains several concepts from other programming languages, it is generally not considered a direct descendant of any other programming language. -

Inform
The core software distribution for the Inform 7 programming language
Inform is the core distribution of a powerful programming language and design system created for writing interactive fiction, where authors describe stories as text adventure games that players explore through typed commands. The language is distinctive for its natural-language-inspired syntax that reads almost like English, allowing storytellers to define rooms, objects, characters, and narrative logic in an intuitive way that emphasizes expressive clarity and literary structure. When you write in Inform, the source code is compiled into playable story files that run on interactive fiction virtual machines such as Z-machine or Glulx, enabling classic text-based gameplay with modern tooling. Inform handles the underlying complexities of text parsing, world modeling, state management, and player input, so authors can focus on narrative design rather than low-level engine details. -

zerolang
The programming language for agents
zerolang, also called Zero, is an experimental agent-first programming language from Vercel Labs. It explores what programming might look like when AI agents are treated as primary users from the start. The language aims to be small, regular, and easy for agents to learn from examples, diagnostics, and documentation. Its tooling is designed to expose structured facts for checking, running, formatting, debugging, repair, graph inspection, and size reporting. The project is pre-1 and intentionally unstable, so it is intended for isolated experimentation rather than production systems. zerolang is most useful as a research platform for developers interested in AI-native programming languages, agent-readable tooling, and repair-oriented development workflows. -

Ficl is a lightweight, embeddable scripting language designed to be incorporated into other programs, and especially embedded systems that may have memory and OS constraints. Applications include scripting, hardware bring-up, rapid prototyping, and system extensions. Unlike Lua or Python, Ficl acts as a component of your system - you feed it stuff to do, it does the stuff, and comes back to you for more. You can export compiled code to Ficl, execute Ficl code from your compiled code, or interact. Your choice.

Churmant
a Lua-like syntax programming language
Churmant (cure-ment), is a compiler for C language, it's used for producing Lua-like code, but also run in a blazingly fast speed, when compared to others. It also is very easy to maintain and read the header file, if you want to contribute. The reason why Churmant is its own language, is because its syntax are not like C entirely, like normal keyword cannot be stack inside each other, for example. -

BMDFM
Binary Modular DataFlow Machine (BMDFM)
Binary Modular DataFlow Machine (BMDFM) is a software package that enables running an application in parallel on shared memory symmetric multiprocessing (SMP) computers using the multiple processors to speed up the execution of single applications. BMDFM automatically identifies and exploits parallelism due to the static and mainly dynamic scheduling of the dataflow instruction sequences derived from the formerly sequential program. The BMDFM dynamic scheduling subsystem performs a symmetric multiprocessing (SMP) emulation of a tagged-token dataflow machine to provide the transparent dataflow semantics for the applications. No directives for parallel execution are needed. More info: http://www.bmdfm.com -
