Takibi is a research systems language and a Linux-ABI-compatible monolithic kernel designed to shift kernel runtime failures to compile-time errors using refinement types and affine ownership.

Oxc is a collection of high-performance JavaScript and TypeScript tools written in Rust, designed for parsing, transformation, and linting.

Nuitka is a Python compiler that translates Python code into C, producing standalone executables or extension modules. Compatible with Python 2.6-2.7 and 3.4-3.14, it works across Linux, macOS, and Windows. Supports multiple compilation modes including standalone distribution.

Marked is a fast, lightweight Markdown parser and compiler that works in browsers, on Node.js servers, and via CLI. It supports all standard Markdown features, custom extensions, and is easily adaptable for different use cases.

Webpack is a module bundler that bundles JavaScript files for use in the browser and can transform, bundle, or package almost any resource or asset. It supports ES modules, CommonJS, AMD, loaders, plugins, code splitting, and production optimizations.

vos is an open programmatic video engine that treats video as a deterministic function of time, allowing for resolution-independent rendering and data-driven editing.

Next.js is Vercel's open-source React framework for building full-stack web applications. It extends the latest React features and integrates Rust-based JavaScript tooling for fast builds, and is used by some of the world's largest companies.

Gatsby is a free, MIT-licensed open-source framework built on React for creating fast websites and apps. It loads data from Markdown, headless CMS, REST or GraphQL sources through source plugins behind a uniform GraphQL interface, and supports per-page SSG, DSG and SSR rendering with built-in code splitting, image optimization and prefetching.

Zap is a general-purpose programming language with a standalone native runtime, offering clear syntax, optional typing, and built-in web capabilities without external dependencies.

Xag is a compiled programming language featuring Rust-style memory ownership, high performance focus, and detailed error messages. It compiles to native code via LLVM or runs through interpreters. Early work-in-progress with strong decimal arithmetic verification against hardware and independent references.

A powerful, markup-based typesetting system designed as a modern, easier-to-learn alternative to LaTeX with fast incremental compilation.

The main source code repository for the Rust programming language, including its compiler, standard library, and documentation.

Synth is an ahead-of-time WebAssembly-to-native compiler targeting ARM Cortex-M/R, RISC-V RV32IMAC and AArch64, with Rocq mechanized correctness proofs and SMT translation validation. Pre-release, embedded-focused, Apache-2.0.

esbuild is an extremely fast JavaScript bundler for the web, built in Go. It natively supports JavaScript, CSS, TypeScript and JSX, bundles ESM and CommonJS, and offers tree shaking, minification, source maps, a local server, watch mode and plugins via CLI, JS and Go APIs.

Kotoba is a security-first, declarative language and computing stack for AI agents that enforces capability-safe execution, post-quantum cryptography by default, content-addressed artifacts, and explicit authority boundaries to confine untrusted code.

PB-Compiler is a from-scratch C# compiler for the PowerBASIC family (including QuickBASIC and Turbo Basic). It generates authentic 16-bit DOS MZ executables with byte-identical fidelity to original compilers. Features include an SSA-based optimization pipeline, support for modern language extensions in pb36, and cross-platform execution on 64-bit hosts.

LAMINARIA is a research-stage unified toolchain that models Rust and Nim builds as one explainable action graph, spanning dependency resolution, compiler pipelines, backend routes, caching and resource-aware execution.
