Microterm is a fully compliant Linux virtual machine that runs in any browser tab. It is designed for real development and operations workflows, not demo-only terminal output. You can use it on desktop, tablets, and phones, including iOS home-screen PWA installs. Under the hood, Microterm combines Restty (libghostty + WebGPU) web terminal rendering and a TinyEMU-backed Alpine Linux guest on RISC-V64. The VM image is chunk-loaded in the browser and booted locally. I successfully used it to run Codex directly without leaving an in-app preview inside X app or Telegram :) Can be used to SSH to…

Bash4LLM is a single-file Bash wrapper for interacting with LLMs from the terminal. I created it because I wanted something simple that worked without installing Python, Node, or any other runtime. It uses only Bash, curl, and jq. You can send prompts, start a small chat, process files line by line, stream output, and save session metadata in JSON format. I tried to make it safe and predictable: no use of the system /tmp, no use of eval. Groq is supported by default, and other providers can be added with dedicated Bash scripts in the extras/providers/ folder. Example: echo…

FerroTerm is a Terminal Emulator (xterm/vt100) / Library witten in Rust and compiled to WebAssembly. It is approx 4x faster than xterm.js which is used by VSCode etc. and prodvides wide spec coverage. https://datanoisetv.github.io/ferroterm/ Would love some feedback and hear what people want to build with it.

Slupe lets you use web-based LLMs to modify local files without leaving the browser. npx slupe --clipboard It's a CLI tool that watches for LLM commands and executes them on your computer. Key features: - Custom syntax (NESL) designed for LLM reliability - fewer search/replace failures than existing approaches - Clipboard mode: copy from browser → Slupe executes → paste results back to clipboard - Generates instructions for LLMs based on your allowed actions - Sandboxed filesystem operations with configurable permissions + automatic git backups Motivation: I wanted to use web based Opus…

Hello, Motivated by this discussion https://goo.gl/te4BFv, I have created a simple (free and open-source) command line note organizer. The tool, called npmnotes, take a folder with notes (written in markdown/texdown) and creates a webpage that lets you search and browse through the notes. You can then publish this webpage or use it locally. The result (built with npmnotes) looks something like this https://npmnotes.org. Currently, this is just a (working) prototype and I plan to add more features soon (based on the feedback I get). What do you think of it?

Hi HN! I built a CLI tool called ShellTalk for macOS, Linux, and web (WebAssembly) that maps English text to the corresponding Bash commands. ShellTalk is written in Swift and available under the Apache 2.0 license on GitHub. I was inspired a few weeks ago after reading the Meta-Harness paper and seeing a tool called Hunch that did something similar using the Apple Foundation model. I often forget flag names and orders, but I wanted something that worked consistently. The 3B AFM worked surprisingly well with Hunch, but it felt slow and sometimes slight changes in what I wrote would result in…

I built a small demo showing a robotics runtime executing entirely inside the browser via WebAssembly. The example workload is a simple flight controller hooked up to a small world simulator. The runtime comes from copper-rs, an open-source robotics runtime written in Rust for deterministic workloads. While robotics stacks are often tightly coupled to specific OS distributions and environments, here, the same code runs on microcontrollers (for example this flight controller also compiles for STM32H7 and flies real drones) as well as on desktop OS targets like Linux, macOS, and Windows. The…

Hi HN, I just wanted to share what I have been working on for the past few months: A firmware analyzer for embedded Linux systems that helps uncovering security issues running entirely in the browser. This is a very early Alpha. It is going to be rough around the edges. But I think it provides quite a lot of value already. So please go ahead and drop a firmware (only .tar rootfs archives for now) and try to break it :)

I use this as my regular xterm replacement... Why? Because I can. It's pure-Ruby down to the font-renderer, and the X11-bindings. (I also run a Ruby WM, a Ruby editor, file manager, and more, so this is just par for the course of my descent into madness) It supports double-width and double-height text, unicode (but double-width characters may currently be rescaled down), layering fonts, special rendering of box-drawing characters (to ensure they seamlessly scale and connect, and has reasonably complete vt-100/vt-102 emulation. The whole thing is available as a Rubygem and comes with an…

Claude Code's --dangerously-skip-permissions flag lets agents run without interruption, but it needs a sandboxed environment to be safe. dangerously is an open source tool that spins up an isolated container and runs Claude Code inside it — file system changes are restricted to your project directory. The new version detects your docker-compose.yml and spins up your full service stack alongside Claude Code, so the agent can test against real dependencies — databases, queues, whatever your app needs. npm install -g dangerously

I wrote a tutorial on how to create Bash scripts, where the command line interface runs entirely in the browser using v86 (https://github.com/copy/v86), and the code editor uses Monaco.

I built an open-source malware detection daemon that monitors all running processes in real-time using ML + heuristics. No kernel modules or eBPF required. Key points: - Polls /proc for new processes (works on any Linux kernel 2.6+) - Random Forest model trained on EMBER 2018 dataset (2.3M samples) - Heuristic rules for crypto miners, ransomware, rootkits - ~20MB RAM, <1% CPU, sub-millisecond scan latency - Pure C, zero runtime dependencies - Model embedded directly in binary (50KB) Why I built this: Existing solutions either require modern kernels (eBPF) or are heavy/proprietary.…
