Mach – A compiled systems language looking for contributions
Hi HN, I'm the creator of Mach (https://github.com/octalide/mach or https://machlang.org). Two days ago, we finally achieved full self hosting. I wanted to make a post here to show off the language since this is a big milestone for us. ## TL;DR about the language for those curious: - There are no external dependencies anywhere in the pipeline. This includes LLVM, libc bindings, or anything of the sort (save for the historical bootstrap compiler, which requires any C compiler and has been phased out completely). - Mach is extremely opinionated and very…
Mach – A compiled systems language looking for contributions launched on June 8, 2026 with 32 votes, #727 of 22,647 launches that month and more than 95% of that year's launches.
In plain words
Mach is a compiled systems language that has achieved self-hosting with no external dependencies in its pipeline, including LLVM or libc bindings. Designed for developers who prioritize transparency, it emphasizes explicit code with no hidden behaviors, implicit conversions, or automatic features. The language aims for simplicity and clarity while targeting performance comparable to C, and is currently seeking contributors to further its development.

A systems programming language with no hidden behavior. - briar-systems/mach
Mach is a self hosted, statically-typed, compiled systems language designed to be simple, fast, verbose, and intuitive. Mach was created for projects like compilers, runtimes, operating systems, tooling, and embedded systems -- anywhere performance is a requirement and hidden behavior is a liability. The language is deliberately small and explicit: what you read is what executes, every cost is visible in the code that incurs it. The compiler, code generators, and linker are written in native Mach, with no LLVM or external assembler or linker. Ordinary Linux programs using the standard library need no libc. The standard library uses platform libraries where required, including libSystem on…from github.com

ScrapScript – A tiny functional language for sharable software2023 · scrapscript.org · ▲503Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at [email protected] if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :)

Axe - A Systems Programming Language with Builtin Parallelism and No GCNov 2025 · axelang.org · ▲16I'm writing a compiler for a systems language focused on concurrency and parallelism. It’s a re-engineering of a prior work, with an explicit emphasis on memory management and type safety, plus first-class parallel primitives at the language level. The language is now capable of compiling a substantial portion of its own source code to tokens using a single-pass C back-end. The self-hosted compiler includes a handwritten lexer and a parser, with an arena-based allocator to support fast compilation and eliminate GC complexity. The primary goals for the project are: First-class parallel and…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
