Shifu – A pure POSIX shell framework to create powerful CLIs
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…

Crust – A CLI framework for TypeScript and BunMar 2026 · github.com · ▲95We'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…
Pu.sh – a full coding-agent harness in 400 lines of shellApr 2026 · pu.dev · ▲92I originally was just messing with pi-autoresearch. Gave it a sample task to build the most portable coding agent. First cut was 6 KB of shell. Great for one-shots, unusable interactively. I was shocked it actually worked. Started building up -- adding features — but with a self-imposed rule: no new dependencies, and sub 500 LOC. This thing had to be truly portable. Just sh, curl, awk. System primitives only. Which means I did some genuinely disgusting things in awk, including JSON parsing and the OpenAI Responses tool loop with reasoning items carried across turns. It's now ~400 lines. In…
Just.sh – compiler that turns Justfiles into portable shell scripts2023 · github.com · ▲64Justfiles are like Makefiles, except Just is a command runner, whereas Make is a build system. As I understand it, Just was built to be a less arcane version of Make for collecting commands common to a code repository. When I first learned about Just, I realized that parsing arguments and running commands is exactly what shell scripts do, and there probably isn't much Just does that sh doesn't. This project proves that hypothesis by compiling Justfiles to portable (POSIX-compatible) shell scripts. just.sh is particularly useful for running Justfiles in esoteric environments where Just may…
Clamshell- an experimental Python based shell2023 · github.com · ▲51About a month ago I started a suprisingly-not-that tricky project to build an experimental python repl that I could use instead of bash as a daily shell in windows, mac or linux. It"s more hack-for-exploration than a production ready shell, but here it is! Hope somebody finds it anywhere near as interesting to check out as I found making it. Disclaimer: I know about xonsh and love it (if you haven't heard of it, google it). This project is more pure python and less python and bash interacting - see the readme for more details.
Shmux – run all your scripts from one file2022 · github.com · ▲26Hello all, This is a small, few hours Holiday project I made out of frustration on what I would have liked makefiles to be but are not. It's rough, but it might be useful for somebody. Any type of feedback is welcome!

Talanoa▲340Hi 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…
