Products that do what PuffinBASIC – A cross-platform modern BASIC interpreter written in Java does
GitHub: https://github.com/mayuropensource/PuffinBASIC BASIC (Beginners' All-purpose Symbolic Instruction Code) is a general-purpose high-level language from the 1960s. PuffinBASIC is an implementation of the BASIC language specification. PuffinBASIC conforms most closely to GWBASIC. The purpose of this implementation is to learn how to write interpreters and resurrect an old programming language to work in modern ecosystem. The interpreter is evolving fast and in near future, I wish to apply modern interpreter building techniques to it. How it works? 1. PuffinBASIC's…

Hi everyone, When the pandemic started, I put QuickBASIC in front of my kids and could see them enjoy toying with writing some simple programs. Since then, I've been working on a side project to build a similar experience using modern technologies, with the goal of having a tool to teach the foundations of programming to (my own) kids. This is what EndBASIC is: is a retro-looking, BASIC interpreter with DOS-like features -- built for the web. The environment is designed to be minimalist in an attempt to reproduce the computing experience of the 1980s where the computers were simpler to…

Hi HN! Silk is a project I began working on approximately six months ago without any prior experience or knowledge of compiler design, and it's been a frustrating but fun learning experience. It is very much a work in progress, but I would love to hear feedback of any kind!

I built LunarBasic because I wanted a modern recreation of BlitzBasic from back in the day. I wanted it to have good step debugging features, and I wanted it to compile down to a native binary with no external dependencies. I do know there's an open source BlitzBasic out there but I wanted something simpler and more concise. It does have a "pro" feature set, but for the foreseeable future, anyone joining up will have the pro version in perpetuity (eg I'm not trying to sell anything here). It's early (v0.8.0). Would love feedback on the language design and compiler output, especially from…

Hi! I am doing a learning project, attempting to build an imperative language (and interpreter). The end product will be useless for others, I just want to learn and better understand how to build imperative languages. :) If someone else shares this interest and want to give some good hints on good resources I would be grateful. Currently I am looking at an awesome text by Bob Nystrom. All suggestions and tips on resources are most welcome. I am very much a beginner in this, but I find this topic very fascinating. Mail me or post links here! Cheers! You can try a beta version Online at…

* https://sparser.io * https://github.com/Unibeautify/sparser This is my attempt at creating a universal language parser. It attempts to solve a couple of problems: * Support multiple languages * Recursively extend support to languages embedded within other languages * Output a uniform format for all supported languages This is a personal project so any feedback would be helpful. Something interesting I found after I built it is that this parser is not as fast to write output as many other JavaScript parsers, but its output is much faster to read from due to the…

https://github.com/PlumeCat/tack Hi HN! Tack is a scripting language I've been working on sporadically for the past year or so, and intensely for the past few weeks. It originated out of a desire for something that was like Lua, but with a more familiar syntax, and without some of the other surprises in Lua such as the 1-indexed tables. It's also been a great learning project, and a very satisfying challenge! While the current version is early beta at best, I hope to continue working on it and maybe see some adoption. Despite the relative lack of optimization, I'm very…

Hi HN, we’re Dylan and Matthew, building sublingual (https://github.com/sublingual-ai/sublingual), an open-source LLM observability tool you can use with zero code changes. As developers focused on iterating and building features as fast as possible, we felt observability would’ve been a helpful tool to have, but we found existing solutions had too much overhead to set up. So we gave ourselves the challenge of building an observability tool that you can integrate without changing a single line of code in your project. How it works Run your python application as usual with…

Hey HN, I'm Mo. I've been building Paseo, an open source environment for running Claude Code, Codex, and OpenCode across desktop, mobile, web, and CLI. It started last September as a push-to-talk voice interface for Claude Code. I wanted to talk to an agent while going on walks. Then I wanted to see what it was doing. Then text it when I couldn't talk. Then review diffs, run multiple agents, and manage work across machines. After a lot of iteration, it turned into a broader environment. The basic model is: - A daemon runs on your machine (MacBook, desktop, VPS, etc.). - Clients connect to it…

Antilisp is a Lisp designed for code generation in non-lisp languages. The interpreter is written in RPython, and the language is designed for easy adoption by non-lispers. The project is still young, but the language can be played with if you don't mind missing some important features like modules and pattern matching. I have not published the source code yet, because I am not completely sure how to base a sustainable business on this project and I don't want to risk having to rugpull after raising expectations.

Hey HN, I’ve spent the last 2 years watching my cousin in Morocco struggle to learn Python. Not because he lacked the brains, but because every tutorial assumed fluency in English. Every new term meant 10 tabs of Google Translate. Turns out, he’s not alone. 75% of the world’s population doesn’t speak English, yet 95% of coding resources are English. So we built FIKR: coding courses taught natively in French, Dutch and German (with more languages coming). Yeah, you can find a random YouTube video explaining Python in French or Arabic. But stitching those into a learning path? It doesn't get…

I built a CLI tool that turns codebases and PRs into diagrams so you can quickly understand how things fit together. Originally made it because I couldn't follow my own AI-generated repos. Just shipped a big update: - Switched from D2 to Mermaid for rendering - Tree-sitter AST parsing + agentic flow instead of raw LLM calls. ~50x faster. - Works on any GitHub repo or PR, not just local - Dropped the web frontend, it's just a CLI now - Published as a pip package Still a ton to improve and I'm building fast. Feedback, issues, PRs all welcome.

After 6 years of coding almost every day, I'm finally ready to show HN. There's a lot going on here, looking forward to your guy's feedback.

I had been looking to try <500M parameter language models but you wouldn't find an API to try them anywhere, so I built this cloudflare hosted static website that hosts weights and built an inference runtime for these models that uses WebGPU and runs inference from your browser. These are only so useful in a multi-turn conversation but it's still interesting to see what you can pack in a <250mb model. I tried using ONNX versions earlier, but there were too many quirks of using them with language models and the TPS wasn't too impressive. Inspired by svenflow/webgpu-gemma, I put my codex…

Hey HN, I'm Mo. I'm building Paseo, a multi-platform interface for running Claude Code, Codex and OpenCode. The daemon runs on any machine (your Macbook, a VPS, whatever) and clients (web, mobile, desktop, CLI) connect over WebSocket (there's a built-in E2EE relay for convenience, but you can opt-out). I started working on Paseo last September as a push-to-talk voice interface for Claude Code. I wanted to bounce ideas hands-free while going on walks, after a while I wanted to see what the agent was doing, then I wanted to text it when I couldn't talk, then I wanted to see diffs and run…

After six months of work, I am here again presenting Fluent – a tiny lang which is optimized for differentiable & reactive programming. Since I am not Conal Elliot, don't expect a beautiful theoretical unification of FRP and AD from first principles. Rather, a horrific monster that holds together mostly because a lot of duct-tape. The link points to the semi-interactive tour of the language, which will get the job done much better than I could in here. Hope you hate/like it!
