Esolang Park, a visual debugger for esolangs
Hey HN! Esolang Park is an online visual debugger interface for esoteric programming languages, that I've been working on for the past few months. For every supported language, Esolang Park provides the powerful Monaco code editor, syntax checking, debugging functionality and a visualisation of the runtime state. The core is language-agnostic - a "language provider" only needs to implement the esolang's parser, interpreter and visualisation UI (and some other little stuff). Apart from trying to boost DX for esolangs, the idea is for this to grow into a platform where people can discover and…

In plain words
Esolang Park is an online visual debugger for esoteric programming languages. It offers a code editor, syntax checking, debugging tools, and runtime state visualization for supported esolangs including Befunge-93, Brainf*ck, Chef, Deadfish, and Shakespeare. The platform uses a language-agnostic architecture where new languages can be added by implementing their parser, interpreter, and visualization components. It is designed for programmers and hobbyists interested in exploring esoteric languages directly in their browser.

Program Explorer, a container playground2025 · programexplorer.org · ▲73Inspired by Compiler Explorer and other playground/fiddle websites like jsfiddle, db-fiddle, Go playground, and Rust playground, I thought it would be cool to have a playground for nearly any program so I've been working on Program Explorer: a playground for running programs from containers. I am inspired by these playgrounds because they are great educational tools for quickly experimenting and as communication tools by sharing shortlinks that reproduce bugs for instance. I would love for every open source project that publishes a container to get their own playground for free. I'm…
Letting LLMs Run a Debugger2025 · github.com · ▲147Hey HN, I just built an experimental VSCode extension called LLM Debugger. It’s a proof-of-concept that lets a large language model take charge of debugging. Instead of only looking at the static code, the LLM also gets to see the live runtime state—actual variable values, function calls, branch decisions, and more. The idea is to give it enough context to help diagnose issues faster and even generate synthetic data from running programs. Here’s what it does: * Active Debugging: It integrates with Node.js debug sessions to gather runtime info (like variable states and stack traces). *…

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…
