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. -

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. -

Ravi Programming Language
Ravi is a dialect of Lua, featuring limited optional static typing
Ravi Programming Language is a derivative of Lua 5.3 with limited optional static typing and MIR-based JIT compiler. Ravi is a derivative/dialect of Lua with limited optional static typing and JIT/AOT compilers. The name Ravi comes from the Sanskrit word for the Sun. Lua is perfect as a small embeddable dynamic language so why a derivative? Ravi extends Lua with static typing for greater performance under JIT compilation. However, static typing is optional and therefore Lua 5.3 programs are also valid Ravi programs. There are other attempts to add static typing to Lua (e.g. Typed Lua but these efforts are mostly about adding static type checks in the language while leaving the VM unmodified. So the static typing is to aid programming in the large - the code is eventually translated to standard Lua and executed in the unmodified Lua VM. -

RaptorJIT
A dynamic language for system programming (LuaJIT fork)
RaptorJIT is a Lua implementation suitable for high-performance low-level system programming. If you want to use a simple dynamic language to write a network stack; a hypervisor; a unikernel; a database; etc, then you have come to the right place. -
13
mruby
Lightweight Ruby
mruby is a lightweight implementation of the Ruby programming language designed for embedding and integration into applications, particularly in resource-constrained environments such as embedded systems or game engines. It maintains compatibility with modern Ruby syntax while offering a significantly reduced footprint compared to the standard Ruby interpreter. The system includes its own virtual machine, bytecode compiler, and interactive shell, enabling developers to write, compile, and execute Ruby code efficiently. One of its core strengths is its embeddability, allowing developers to integrate scripting capabilities directly into applications written in C or C++. mruby also includes a package system called mrbgems, which enables modular extension of functionality through additional libraries. It supports compiling Ruby scripts into bytecode or even C source code, providing flexibility for deployment in different environments. -

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. -

The Acton programming language
The Acton Programming Language
Write programs that seamlessly run as a distributed system over an entire data center or region. All without a single line of RPC code. Acton automatically persists the state of your application (orthogonal persistence) to a built-in distributed backend. No need to use a database or message broker ever again. 0 lines of persistence code. Built-in redundancy; Acton's transactional, high-performance distributed RTS can seamlessly resume application state after hardware failures. Never stop for an upgrade; Live upgrade your running application through compiler-supported code and data migration. Acton programs, and the actor model, work well from simple script-style applications on a single machine up to large distributed systems across a Data Center. Run at your scale. -

Zen C
Write like a high-level language, run like C
Zen C is a minimal yet expressive implementation of the C programming language that aims to balance simplicity with practical capability, making it ideal for educational use, language experimentation, and small-scale systems programming. It provides a clean syntax and semantics that closely mirror classic C while enforcing stricter rules to eliminate common pitfalls like undefined behaviors or hidden conversions that often cause bugs. Zen-C includes a lightweight compiler front-end and runtime that can target multiple platforms, enabling users to compile and run code on both desktop and embedded environments without heavy tooling. Because it prioritizes clarity and predictability, the language makes it easier for learners to understand core systems concepts while still accessing low-level memory control and performance. -

Gravity language
Gravity Programming Language
Gravity is a powerful, dynamically typed, lightweight, embeddable programming language written in C without any external dependencies (except for stdlib). It is a class-based concurrent scripting language with modern Swift-like syntax. Gravity supports procedural programming, object-oriented programming, functional programming, and data-driven programming. Thanks to special built-in methods, it can also be used as a prototype-based programming language. Gravity has been developed from scratch for the Creo project in order to offer an easy way to write portable code for the iOS and Android platforms. It is written in portable C code that can be compiled on any platform using a C99 compiler. The VM code is about 4K lines long, the multipass compiler code is about 7K lines and the shared code is about 3K lines long. The compiler and virtual machine combined add less than 200KB to the executable on a 64-bit system. -

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.
