  10. darklua

    A command line tool that transforms Lua code

  11. alef

    Generate fully-typed, lint-clean language bindings for Rust libraries across 16 languages

    Project mention: One Rust core, native SDKs in 16 languages: how we stopped hand-writing bindings | dev.to | 2026-07-06

    The tool is alef. It extracts the Rust API surface and emits language-native bindings, package scaffolding, type stubs, docs, and e2e tests from one alef.toml:

  12. code-muse-rs

    generate apps using prompt engineering and the OpenAI API

  13. libmake

    A code generator to reduce repetitive tasks and build high-quality Rust libraries. 🦀

  14. almide

    A statically-typed programming language optimized for LLM code generation. Compiles to Rust and WebAssembly.

    Project mention: AI wrote my compiler. A mathematical proof checks its work on every build. | dev.to | 2026-07-24

  15. RustyLR

    A Bison-inspired parser generator and compiler frontend framework for Rust, with IELR(1), LALR(1), GLR, and LSP support.

  16. patchloom

    Structured file edits for AI agents (JSON/YAML/TOML, markdown, AST, dry-run, MCP). Not a generic filesystem MCP.

    Project mention: Patchloom – structured file edits for AI agents (CLI and MCP) | news.ycombinator.com | 2026-08-08

  17. rask

    A modular, low-level code generation toolkit for Rust. (by chrischtel)

    Project mention: Building an x86-64 instruction encoder in Rust | news.ycombinator.com | 2025-10-07

    I’ve been working on Rask, a small x86-64 instruction encoder written in Rust.

    It’s designed for people who want to understand how compilers emit machine code — without the complexity of LLVM or Cranelift.

    It currently supports mov/add/sub/ret with correct REX and ModR/M encoding, and includes tests verifying the byte output.

    Repo: https://github.com/chrischtel/rask

    Feedback welcome, especially from anyone who’s worked on compiler backends or JITs.

  18. buildlang

    A systems language with typed capability effects, sum types, C FFI, native binaries through its production C path, and HLSL/GLSL output. Linear types and non-C backends remain experimental. Ships as buildc.

    Project mention: Five short papers on making AI-assisted work re-checkable | dev.to | 2026-07-06

    BuildLang — a compiler that puts ambient capabilities in the function type and seals re-derivable receipts verified by re-execution. 10.5281/zenodo.21231253 · source

  19. carrier

    Turn business specs into production-ready APIs with built-in auth, DB, and compliance. (by nikoma)

    Project mention: We rebuilt our auth back end in under an hour using a DSL/compiler approach | news.ycombinator.com | 2026-05-06

  20. rucc

    An optimizing C compiler written in Rust. Verified rewrite rules, acyclic e-graphs, no external assembler. The target ladder is SQLite, then PostgreSQL, then the Linux kernel. (by tamnd)

    Project mention: Show HN: Rucc – C compiler in Rust, now compile and run SQLite | news.ycombinator.com | 2026-09-07

  21. phonton-cli

    Open-source Phonton CLI: a local-first agentic development terminal with context packs, source handles, and verification gates.

    Project mention: Building Phonton: a local-first AI coding CLI that verifies diffs before review | dev.to | 2026-05-02
