Languages

A browser-based QBasic 1.1 editor and interpreter that runs classic QBasic programs with DOSBox-accurate behavior, including text-mode graphics commands such as PRINT, COLOR and LOCATE, with sample programs and keyboard shortcuts to run and save.

• Editors
• Languages

A Brainfuck-inspired esoteric programming language adding absolute memory navigation, multiplier arithmetic, non-destructive inspection and inline conditionals, with its own interpreter.

• Languages

An in-browser playground that compiles and runs the C3 programming language entirely in WebAssembly, with no backend server, alongside its standard library and documentation.

• Languages

A human-reviewed directory of projects built with the Bend 2 programming language, covering apps, games, developer tools, libraries, and research experiments, each linked to its source.

• Languages
• Curated lists

A release post for the Chuks backend programming language describing forty-five fixes found in its v0.2.0 release candidate, almost all discovered by real programs rather than its test suite.

• Languages

An interactive debugger for the Mornington Crescent esoteric programming language that visualizes program execution as a route through the London Underground map.

• Debugging
• Languages

An esoteric programming language with exact dyadic-rational arithmetic and a self-hosting compiler that must reproduce its own binary image byte-for-byte before a release.

• Languages

A Python source preprocessor where every if, elif, while and match statement is decided by an LLM reading the surrounding code and variables, instead of by Python's own rules.

• Languages

A statically-typed, compiled programming language with a from-scratch native backend, designed to be written by AI coding agents and easy for a reviewer, human or model, to check rather than terse to type.

• Languages

An experimental Haskell compiler, written incrementally by AI models, tracked as a percentage of the Stackage package set it can successfully build.

• Languages

A C# REPL library that can be embedded in any .NET application, with syntax highlighting, code completion and runtime type introspection.

• Languages
• Libraries

A systems programming language in which the architecture — boundaries, protocols and proof obligations — is executable, and any implementation of it can be replaced.

• Languages

An Elixir mix task that generates Elixir code from Protocol Buffers definitions by calling protoc directly, running in the local project's context instead of as a global protoc-gen-elixir plugin.

• Languages

A Rust proc-macro SDK, released as the typebridge CLI, that generates matching TypeScript, Python Pydantic, Go, Swift, Kotlin, GraphQL, JSON Schema, Ruby, PHP and Dart types from annotated Rust structs and enums.

• Languages
• Libraries

A Dart code generator that regenerates class members such as copyWith, equality, hashCode and typed JSON inside the same file on every save, using team-owned Mustache templates instead of build_runner part files.

• CLI tools
• Languages

A domain-specific language and toolchain that replaces Graphviz DOT as the authoring format for AI pipeline workflows, giving prompts, shell scripts, model configuration and branching first-class syntax.

• Agent frameworks
• Languages

An independent, statically typed Lisp derived from Clojure, with one checker and canonicalizer that targets Clojure, JavaScript and Nix as hosted profiles, plus an experimental native compilation path.

• Languages

A Scala 3 toolchain that compiles straight to a native executable through Scala Native, with a self-hosted compiler, linker and build tool that require no JVM at all.

• Languages

A programming language and runtime for building AI agents that manages model calls, tool execution, permissions and history, so the same agent code can run against local or hosted models.

• Agent frameworks
• Languages

The Super Tiny Compiler, a well-known minimal educational compiler example, reimplemented in Ada, taking a small Lisp-like expression and compiling it to a line of C-style function-call code.

• Languages
• Tutorials

A statically-typed language, compiling to native binaries via Rust and to WebAssembly with byte-identical output, designed around one metric: how often code still compiles and passes its tests after a series of AI-driven edits.

• Languages

AILANG is a purely functional, effect-typed programming language designed as a deterministic execution substrate for AI-generated code, with reflectable and verifiable semantics for every construct.

• Languages

A work-in-progress, multi-paradigm compiled programming language designed to be simple for a large language model to write and easy for a person to read, aiming for performance within about 15% of C.

• Languages

An unreleased, alpha-stage low-level systems programming language built around explicit memory and execution control, typed failures and deterministic cleanup, with a self-hosted stage-0 compiler that emits native code and WebAssembly through LLVM.
