Whetuu – a zero-config cross-shell prompt written in Zig

From the sources

Your prompt runs before every command, so whetū renders in about 2 ms. One compiled binary, no config file, nothing to theme, nothing to tune — the same curated prompt for everyone. Git branch, state and status. Toolchain versions for 39 languages. A syntax-highlighted history picker on the up arrow. Written in Zig, every disk probe running at once, so a render costs what its slowest one costs. No network, no telemetry, no account. macOS and Linux, on fish, bash and zsh.

An opinionated, zero-config status line and history picker for fish, bash and zsh, written in Zig. One compiled binary renders one curated status line, the same for everyone. There is no config file, nothing to theme and nothing to tune, and it renders in about two milliseconds. It also puts your history on the up arrow. One binary does both, so the picker knows where you are. It opens on what you ran in this directory, and Ctrl+G switches to all of it. Failed commands are never stored, so you do not scroll past your own typos. Your own shell history stays exactly where it is. Download the binary. Grab the tarball for your platform, check it against the published SHA256SUMS , and put it on…from yamafaktory.github.io

  Zigg.be – A link shortener that creates short speakable links2013 · zigg.be · ▲75

  I created this a year or so ago but recently made updates and I thought people might like to know that it exists. I made this to easily send links or text to someone else verbally, like over the phone or over voice chat (which is what I made it for). The goal is to be able to tell the link to someone else without being ambiguous or needing to spell it out, so I grabbed the words off a Grade 5 level dictionary. I understand that the domain itself doesn’t qualify but I’m trying to get a better domain.

  Zli – A Batteries-Included CLI Framework for Zig2025 · github.com · ▲95

  I built zli, a batteries-included CLI framework for Zig with a focus on DX and composability. Key features: - Typed flags with default values and help output - Rich formatting, and layout support - Command trees with isolated execution logic - It’s designed to feel good to use, not just to work. - Built for real-world CLI apps, not toy examples. Would love feedback, feature ideas, or thoughts from other Zig devs. repo here: https://github.com/xcaeser/zli

  Talanoa▲340

  Hi 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…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
