After having cycled through various CLI-based todo apps, I started to realise that I actually don’t need a tool at all for managing my todos. Most of the time, my use cases are quite simple, like viewing my todo items, checking them off, or adding a new one. Rather than having to memorise CLI commands for these interactions (which I’m not super good at), I figured that it’s easier for me to use my text editor directly, and have an editor plugin help me with the visual structure and some convenience functionality. So, kind-of similar to Emacs Org Mode, but without having to use Emacs. I…

We've been building Crust (https://crustjs.com/), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…

I built a Rust-based CLI/terminal UI for inspecting Parquet files—data, metadata, and row-group-level structure—right from the terminal. If someone sent me a Parquet file, I used to open DuckDB or Polars just to see what was inside. Now I can do it with one command. Repo: https://github.com/kaushiksrini/parqeye

Hi HN! I wanted to share Yakari, a tool I built to make command-line interfaces more approachable through interactive TUIs. If you've ever forgotten CLI flags or needed to look up command syntax, this might help. Yakari turns complex commands into interactive menus. Users can navigate through options with simple key presses instead of memorizing complex command structures. If you've used Emacs and Magit (or any other Transient) before, the interface will feel familiar. Features: - Transform CLIs into guided menus - Create custom menus for any CLI - Support for flags, named parameters,…

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…

Last month, I started learning a Python TUI framework called Textual. After working on a 4x4 board game, I made an interactive app to test your CLI text processing skills with 40 beginner to intermediate level exercises. The app is fairly basic in terms of features — only single input file, so no stdin data, multiple files, etc. Most of the exercises in this app is based on my Computing from the Command Line ebook (https://learnbyexample.github.io/cli-computing/preface.html). I hope to improve the TUI app to support all the 200+ exercises sometime next year.

Hi HN, I’m one of the maintainers of Bridge Anonymization. We built this because the existing solutions for translating sensitive user content are insufficient for many of our privacy-concious clients (Governments, Banks, Healthcare, etc.). We couldn't send PII to third-party APIs, but standard redaction destroyed the translation quality. If you scrub "John" to "[PERSON]", the translation engine loses gender context (often defaulting to masculine), which breaks grammatical agreement in languages like French or German. So we built a reversible, local-first pipeline for Node.js/Bun. Here…

The startup I work for has an internal, bash-based, cli that basically amounts to shared aliases with a common entrypoint. As the number of aliases has grown, I've had a desire to group functionality together in subcommands, add more help strings, and have better tab completion. I know I could convert it to, e.g., a python script, but I was curious what was possible if we continued to use bash. I couldn't find anything that solved those problems without lots of extra machinery. I understand why, shell scripts are generally not long, and focused on a dedicated task; adding cli features to…

Hello HN, We are the team behind Tabstack (https://tabstack.ai) - part of Mozilla. We just open sourced Pilo (pronounce PIE-low), the core engine that powers our automation platform. You can check it out on Github at https://github.com/mozilla/pilo. Pilo is an agentic web automation library. Instead of writing rigid scripts with CSS selectors, you give it a natural language goal (e.g., "Find the best pizza in Seattle and extract the ratings") and it autonomously navigates the browser to achieve it. We built this because we were struggling to make reliable agents…

I've created cppmatch, a lightweight, header-only C++ library that brings Rust-inspired pattern matching and error handling to C++. It tries to imitate the functionality of the questionmark (?) operator in C++ by using a macro that uses the gcc extension https://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html This allows to create exceptionless code with non-intrusive error-as-value that unlike Exceptions, makes it clear which kinds of error a function can generate and forces you to handle (or ignore) them. The ? operator translates to *expect* To handle the errors I…
